AI Agents: More Than Chatbots, Less Than Sci-Fi

2025-12-21 23:35:04

When you hear AI agents, what comes to mind?

Cyborg gif

For many people, it’s sophisticated bots running around on their own, something straight out of a sci-fi movie. And while there is a tiny bit of truth in that, the reality is far less dramatic and far more useful.

At their core, AI agents are simply software systems that can think, decide, and act on their own with little to no human intervention.

Think of them as smart assistants, not robots.

Imagine telling your assistant:

"I need a weekly report."

Instead of just giving suggestions, the agent:

  • figures out what should go into the report,
  • gathers the relevant information,
  • compiles it,
  • and even emails it to your team lead.

That’s an AI agent in action.

Where Do We Draw the Line Between AI Agents and Chatbots?

This is where most confusion happens.

Chatbots

Chatbots are reactive.

They respond to prompts and guide you through tasks.

A chatbot can:

  • help you draft a report,
  • suggest improvements,
  • help write an email.

But you still do the execution copying, pasting, sending, deciding the next step.

AI Agents

AI agents go a step further.

They don’t just assist,they execute.

An AI agent can:

  • plan the steps needed to complete a task,
  • take actions on your behalf,
  • use tools,
  • and decide what to do next based on results.

Chatbots talk. AI agents act.

What Powers AI Agents? (Their “Superpowers”)

AI agents work because of a few key capabilities working together:

1. Memory

AI agents can remember past interactions, data, or outcomes.

This allows them to learn from previous tasks and improve over time.

2. Reasoning

They can break down complex tasks into smaller, logical steps.

Instead of being told every single action, they figure out how to get things done.

3. Tools & Actions

AI agents can use external tools, such as:

  • databases,
  • APIs,
  • browsers,
  • files,
  • calendars,
  • email systems.

This is what allows them to actually do things, not just suggest them.

4. Autonomy

Once given a goal, an AI agent can work independently:

  • no fatigue,
  • no boredom,
  • no constant prompting.

This autonomy is what separates agents from traditional automation.

So… What’s the Big Deal About AI Agents?

Big deal gif

Here’s where it really clicks.

Illustration: Chatbot vs AI Agent in Real Life

Scenario: Scheduling a team meeting

With a chatbot:

  1. You ask for help scheduling.
  2. It suggests possible times.
  3. You check calendars.
  4. You send emails.
  5. You follow up manually.

With an AI agent:

  1. You say: "Schedule a team meeting for next week."
  2. The agent:
    • checks everyone’s availability,
    • picks an optimal time,
    • sends calendar invites,
    • sends reminders,
    • reschedules if conflicts appear.

You don’t manage the steps the agent does.

Why This Matters

AI agents can:

  • handle repetitive tasks (scheduling, reminders, follow-ups),
  • run automations (customer support, internal workflows),
  • monitor systems and trigger actions when something changes.

This frees humans to focus on:

  • creativity,
  • decision-making,
  • strategy,
  • and problem-solving.

Types of AI Agents

AI agents come in different forms depending on what they’re built to do:

  1. Task Agents

    Focus on a single job (e.g., sending reports, answering tickets).

  2. Workflow Agents

    Handle longer chains of steps and decisions.

  3. Multi-Agent Systems

    Multiple agents working together, each with a role, like a team.

  4. Embedded Agents

    Built directly into apps or systems to quietly assist in the background.

How AI Agents Actually Work (High-Level Flow)

You can think of an AI agent’s workflow like this:

Request
   │
Think
   │
Decide
   │
  Act
   │
Observe
   │
Improve

  1. A request is made.
  2. The agent reasons about the task.
  3. It selects the right tools.
  4. It performs actions.
  5. It observes the results.
  6. It adjusts if needed.

No sci-fi. Just structured decision-making.

Final Thought

AI agents aren’t here to replace humans or take over the world.

They’re here to handle the busy work: the repetitive, time-consuming tasks that slow teams down.

Think of them as reliable digital coworkers:

quiet, tireless, and surprisingly practical.

Is Gemini 3 Pro Good for Coding? A 2026 Reality-Check and Practical Guide

2025-12-21 23:33:17

Google’s Gemini 3 Pro arrived as a headline-grabbing multimodal model that Google positions as a major step forward in reasoning, agentic workflows, and coding assistance. In this long-form piece I note to answer one clear question: Is Gemini 3 Pro good for coding? Short answer: Yes — with important caveats. Below you’ll find evidence, use-cases, limitations, and concrete adoption advice so teams and individual developers can decide how to use Gemini 3 Pro effectively and safely.

Currently, CometAPI that aggregates over 500 AI models from leading providers) integrates Gemini 3 Pro and Gemini 3 Flash APIs, and the API discounts are very cost-effective. You can first test the coding capabilities of Gemini 3 Pro in the CometAPI interactive window.

What is Gemini 3 Pro and why does it matter for developers?

Gemini 3 Pro is the flagship release in Google’s Gemini 3 family — a multimodal (text, code, image, audio, video) model series built to improve depth of reasoning and agentic capabilities. Google launched Gemini 3 Pro in mid-November 2025 and positioned it explicitly as their “best vibe coding model yet,” making strong claims about reasoning, multimodal understanding, and integration into developer toolchains.

Why it matters: unlike earlier assistants that were optimized primarily for natural-language assistance or shorter code snippets, Gemini 3 Pro was designed from the ground up for deeper, longer-form reasoning and more autonomous agent-style coding — e.g., generating multi-file projects, running terminal-like operations via agents, and integrating with IDEs and CI systems. For teams that want an AI to do more than patch single functions — to scaffold applications, propose architecture changes, and handle multi-step development tasks — Gemini 3 Pro signals a new capability tier.

What are the headline specs that matter for coding?

Three specs stand out for coding workflows:

  • Context window: Gemini 3 Pro supports extremely large input contexts (public reporting and model trackers reference context capacities up to roughly 1,000,000 tokens in some variants), which matters for handling large codebases, long diffs, and multi-file projects.
  • Multimodality: It accepts code and other media types (images, audio, PDFs), enabling workflows like analyzing screenshots of error messages, reading docs, or processing design assets alongside code. which also helps when you want the model to act on screenshots, design mockups, or spreadsheets while producing code. That’s critical for frontend engineers translating wireframes to HTML/CSS/JS.
  • Reasoning improvements: Google emphasized new reasoning modes (Deep Think / dynamic thinking) intended to produce longer, more accurate chains of logic — a desirable property when planning complex algorithms or debugging multi-step failures.

These characteristics are promising on paper for coding tasks: large context reduces the need to compress or summarize repositories, multimodality helps when debugging from error screenshots or log attachments, and better reasoning helps with architecture and complex bug triage.

How does Gemini 3 Pro perform on real programming tasks?

Code generation: correctness, style and maintainability

Gemini 3 Pro consistently produces idiomatic code and — importantly — shows an improved ability to reason about architecture and multi-file projects. Several hands-on reports demonstrate that it can generate scaffolded applications (frontend + backend), translate designs into working prototypes, and refactor larger codebases with fewer context-limitation problems than earlier models. However, real-world correctness still depends on prompt quality and human review: the model can still introduce subtle logical errors or make unsafe assumptions about environment state.

Debugging, terminal tasks, and “agentic” coding

One of Gemini 3 Pro’s headline features is agentic or autonomous coding — the ability to reason about tasks, run through multi-step workflows, and interact with tools (via API or a sandboxed execution environment). Benchmarks such as Terminal-Bench show that the model is substantially better at tasks requiring command-line navigation, dependency management, and debugging sequences. For developers who use AI to triage bugs, create debugging scripts, or automate deployment tasks, Gemini 3 Pro’s agentic abilities are a major plus. But caution: those features require secure gating and careful sandboxing before giving the model access to production systems.

Latency, iteration speed, and small edits

While Gemini 3 Pro’s reasoning strength is excellent for larger tasks, latency can be higher than some competitors when making small iterative edits (fixes, micro-refactors). For workflows that need rapid, repeated edit cycles (e.g., pair programming with instant suggestions), models optimized for low-latency completions may still feel snappier.

Is Gemini 3 Pro safe and reliable enough for production coding?

Factual accuracy and hallucinations

A major caveat: independent evaluations focused on factual accuracy show that even top models struggle with absolute factual correctness in some contexts. Google’s own FACTS-style benchmarks show non-trivial error rates when models are asked to retrieve or assert factual information, and Gemini 3 Pro scored around 69% accuracy on a new FACTS benchmark designed by Google researchers — indicating meaningful room for improvement in absolute reliability. For code, that means the model can confidently produce plausible but incorrect code (or incorrect citations, commands, or dependency versions). Always plan for human review and automated testing.

Security, supply-chain and dependency risks

When a model generates dependency updates, bash commands, or infrastructure-as-code, it can introduce supply-chain risks (e.g., suggesting a vulnerable package version) or misconfigure access controls. Because of Gemini 3 Pro’s agentic reach, organizations must add policy controls, code-scanning, and restricted execution sandboxes before integrating the model into CI/CD or deploy pipelines.

Collaboration and code review workflows

Gemini 3 Pro can be used as a pre-commit reviewer or as part of code-review automation to flag potential bugs, propose refactors, or generate test cases. Early adopters reported it helped generate unit tests and end-to-end test skeletons quickly. Still, automated acceptance criteria should include human verification and failing builds for any model-suggested changes that affect security or architecture.

Comparison of coding: Opus 4.5 vs GPT 5.2 vs Gemini 3 Pro

By many measures, Gemini 3 Pro is a top-tier contender. Public comparisons and trackers show it outranking many prior models on reasoning and long-context tasks, and often matching or edging out competitors on coding benchmarks. That said, the model ecosystem in late-2025 is highly competitive: OpenAI released newer GPT models (e.g., GPT-5.2) with explicit improvements to coding and long-context tasks in direct response to competitor progress. The market is therefore fast-moving, and “best” is a moving target.

SWE-Bench Verified — Real-World Software Engineering Resolution

SWE-Bench is designed to evaluate real-world software engineering tasks: given a code repository + failing tests or an issue, can a model produce a correct patch that fixes the problem?

  • SWE-Bench Verified is the Python-only, human-verified subset (commonly used for apples-to-apples comparison).
  • SWE-Bench Pro is broader (multiple languages), more contamination-resistant and more industrially realistic. (These differences matter: Verified is narrower/easier; Pro is harder and more representative of multi-language enterprise codebases.)

Data table:

Model SWE-Bench Verified Score
Claude Opus 4.5 ~80.9% (highest among competitors)
GPT-5.2 (standard) ~80.0% (close competitor)
Gemini 3 Pro ~74.20–76.2% (slightly behind the others)

Terminal-Bench 2.0 — Multi-Step & Agentic Tasks

Benchmark: Evaluates a model’s ability to complete multi-step coding tasks, approximate real developer agent behavior (file edits, tests, shell commands).

Model & Variant Terminal-Bench 2.0 Score (%)
Claude Opus 4.5 ~63.1%
Gemini 3 Pro (Stanford Terminus 2) ~54.2%
GPT-5.2 (Stanford Terminus 2) ~54.0%

Notes:

  • On Terminal-Bench 2.0, Claude Opus 4.5 leads with a noticeable margin, indicating stronger multi-step tool use and command-line coding proficiency in the leaderboard snapshot.
  • Gemini 3 Pro and GPT-5.2 show similar competitive performance on this benchmark.

What about τ2-bench, toolathlon, and other agentic / tool-use evals?

τ2-bench (tau-2) and similar tool-use evals measure an agent’s ability to orchestrate tools (APIs, Python execution, external services) to complete higher-level tasks (telecom retail automations, multi-step workflows). Toolathlon, OSWorld, Vending-Bench, and other specialized arenas measure domain-specific automation, long-horizon agentic competence, or environment interaction.

Gemini 3 Pro: DeepMind reports very high τ2-bench / agentic tool-use numbers (e.g., τ2-bench ≈ 85.4% in their table) and strong long-horizon results on some vendor tests (Vending-Bench mean net worth numbers).

What is LiveCodeBench Pro (competitive coding)

LiveCodeBench Pro focuses on algorithmic / competitive programming problems (Codeforces-style), often reported as Elo ratings derived from pass@1 / pass@k comparisons and pairwise matches. This benchmark emphasizes algorithm design, reasoning about edge cases, and concise, correct implementations.

Gemini 3 Pro (DeepMind): DeepMind reports a LiveCodeBench Pro Elo ≈ 2,439 for Gemini 3 Pro (their published performance table). Gemini 3 Pro shows particularly strong competition/algorithmic performance in DeepMind’s published numbers (high Elo), which aligns with anecdotal and independent tests that Google’s model is strong on algorithmic problems and coding puzzles.

Final summary

The best, most-relevant benchmarks for judging coding capability today are SWE-Bench (Verified and Pro) for real repo fixes, Terminal-Bench 2.0 for agentic terminal workflows, and LiveCodeBench Pro for algorithmic / competition skill. Vendor disclosures place Claude Opus 4.5 and GPT-5.2 at the top of SWE-Bench Verified (~80% range) while Gemini 3 Pro shows especially strong algorithmic and agentic numbers in DeepMind’s published table (high LiveCodeBench Elo and solid Terminal-Bench performance).

All three vendors highlight agentic / tool-use competence as a primary advancement. Reported scores vary by task: Gemini is emphasized for tool chaining & long context / multimodal reasoning, Anthropic for robust code+agent workflows, and OpenAI for long-context and multi-tool reliability.

Gemini 3 Pro excels at:

  • Large, multi-file reasoning tasks (architecture design, cross-file refactors).
  • Multimodal debugging scenarios (logs + screenshots + code).
  • Terminal-style, multi-step operational tasks.

It may be less attractive when:

  • Ultra-low-latency, tiny prompt workloads are required (lighter, cheaper models may be preferable).
  • Specific third-party toolchains already have deep integrations with other providers (cost of migration matters).

How do you integrate Gemini 3 Pro into a developer workflow?

What tooling exists today?

Google has rolled out integrations and guidance that make Gemini 3 Pro useful inside real development environments:

  • Gemini CLI: a terminal-first interface that allows agentic workflows and enables the model to run tasks in a controlled environment.
  • Gemini Code Assist: plugins and extensions (for VS Code and other editors) that let the model operate on the open codebase and annotate files, with fallbacks to older models when Gemini 3 capacity is constrained.
  • API and Vertex AI: for production deployments and controlled usage in server-side systems.

These integrations are what make Gemini 3 Pro particularly useful: they allow end-to-end loops where the model can propose changes and then run tests or linters to confirm behavior.

How should teams use it — suggested workflows?

  1. Prototyping (low risk): Use Gemini 3 Pro to rapidly scaffold features and UIs. Let designers and engineers iterate on prototypes it generates.
  2. Developer productivity (medium risk): Use it for code generation in feature branches, writing tests, refactors, or documentation. Always require PR review.
  3. Automated agentic tasks (higher maturity): Integrate with test runners, CI pipelines, or the CLI so the model can propose, test, and validate changes in an isolated environment. Add guardrails and human approval before merge.

What prompts and inputs get the best results?

  • Give file context (show the repository tree or relevant files).
  • Provide design artifacts (screenshots, Figma exports) for UI work.
  • Supply tests or expected outputs so the model can validate its changes.
  • Ask for unit tests and testable examples — this forces the model to think in runnable artifacts rather than purely textual descriptions.

Practical tips: prompts, guardrails, and CI integration

How to prompt effectively

  • Start with a one-line goal, then provide exact file paths and tests.
  • Use “Act as” style prompts sparingly — better to provide context and constraints (e.g., “Follow our lint rules; keep functions under 80 lines; use dependency X version Y”).
  • Request explainable diffs: “Return a patch and explain why each change is necessary.”

Guardrails and CI

  • Add a premerge CI job that runs model-generated changes through linters, static analyzers, and full test suites.
  • Keep a human approval step for any change that touches critical modules.
  • Log model prompts and outputs for auditability and traceability.

How to structure prompts and interactions for reliability?

  • Provide explicit context snippets rather than whole repositories when possible, or use the model’s large context to include only focused, relevant files.
  • Ask the model to explain its reasoning and produce stepwise plans before making code changes; this helps auditors and reviewers.
  • Request unit tests alongside code changes so proposed edits are immediately verifiable.
  • Limit automation to non-destructive tasks at first (e.g., PR drafts, suggestions) and move gradually to higher-automation workflows as confidence grows.

Final verdict:

Gemini 3 Pro is very good for coding if you treat it as a powerful, multimodal assistant integrated into an engineering workflow that includes execution, tests, and human review. Its combination of reasoning, multimodal input, and agentic tool support elevates it beyond a mere autocomplete; it can act like a junior engineer that drafts, tests, and explains changes. But it is not a replacement for experienced developers — rather, a force multiplier that lets your team focus on design, architecture, and edge cases while it handles scaffolding, iteration, and routine fixes.

GPT Image 1.5: Feature, Comparison and Access

2025-12-21 23:31:05

OpenAI announced GPT Image 1.5, the company’s new flagship image-generation and editing model, and shipped a refreshed “ChatGPT Images” experience across ChatGPT and the API. OpenAI markets the release as a step toward production-grade image creation: stronger instruction following, more precise edits that preserve important details (faces, lighting, logos), output that’s up to 4× faster, and lower image input/output costs in the API.The good news is that CometAPI has integrated GPT-image 1.5 (gpt-image-1.5) and offers a lower price than OpenAI.

What is GPT Image 1.5?

GPT Image 1.5 is OpenAI’s latest generation image model, released as the engine behind a rebuilt ChatGPT Images experience and made available through the OpenAI API as gpt-image-1.5. OpenAI positions it not just as a novelty art tool but as a production-ready creative studio: it aims to make precise, repeatable edits and to support workflows like ecommerce catalogs, brand asset variant generation, creative asset pipelines, and fast prototyping. Explicitly highlights advances in preserving important image details—faces, logos, lighting—and in following step-by-step editing instructions.

Two operational details to remember: GPT Image 1.5 renders images up to four times faster than its predecessor and that image inputs/outputs are ~20% cheaper in the API compared with GPT Image 1.0 — both important for teams that iterate a lot. The new ChatGPT Images UI also adds a dedicated sidebar workspace, preset filters and trending prompts, and a one-time “likeness” upload for repeated personalizations.

How did GPT Image 1.5 evolve from previous OpenAI image models?

OpenAI’s image line has moved from DALL·E → multiple internal image experiments → GPT Image 1 (and smaller variants). Compared with earlier OpenAI image models (e.g., GPT-image-1 and earlier ChatGPT image stacks), 1.5 is explicitly optimized for:

  • Tighter instruction following — the model adheres more closely to textual directives.
  • Improved image-editing fidelity — it preserves composition, facial features, lighting, and logos across edits so repeated edits remain consistent.
  • Faster, cheaper inference — OpenAI claims up to 4× speed improvements over the previous image model and reduced token/image costs for inputs and outputs.

In short: instead of treating image generation as a one-off “art toy,” OpenAI is pushing image models toward predictable, repeatable tools for creative teams and enterprise workflows.

Main features of GPT Image 1.5

Editing and image-preservation capabilities

GPT Image 1.5 performing strongly across several image-generation and editing leaderboards published since launch.LMArena report GPT Image 1.5 ranking at or near the top of image text-to-image and image-editing leaderboards, sometimes narrowly ahead of competitors like Google’s Nano Banana Pro.

GPT Image 1.5: Feature, Comparison and Access

One of the headline features for GPT Image 1.5 is precise editing that preserves “what matters”: when you ask the model to change a particular object or attribute it aims to change only that element while keeping composition, lighting, and people’s appearance consistent across edits. For brands and ecommerce teams this translates to fewer manual touchups after automated edits.

How fast is it and what does "4× faster" mean?

OpenAI reports that image generation in ChatGPT Images is up to 4× faster than before, ~20% cheaper image I/O costs in the API compared to GPT Image 1. That’s a product-level claim: faster render time means you can iterate more images in the same session, start additional generations while others are still processing, and reduce friction in exploratory workflows. Faster inference not only reduces latency for end-users, it also lowers energy per request and operational cost for deployments. Note: “up to” means real-world gains will depend on prompt complexity, image size, and system load.

Instruction following and text rendering improved

Stronger instruction following versus GPT Image 1.0: the model is better at interpreting multi-step prompts and retaining user intent across chained edits. They also highlight improved text rendering (legible text embedded in images) and better small-face rendering, but it still flags multilingual/text rendering limits in some edge cases, but overall the model aims to close the longstanding gap where generated images would produce illegible or nonsensical signage.

GPT Image 1.5 vs Nano Banana Pro (Google) vs Qwen-Image (Alibaba)?

What is Google’s Nano Banana Pro?

Nano Banana Pro (branded in Google’s Gemini family as Gemini 3 Pro Image / Nano Banana Pro) is Google/DeepMind’s studio-grade image model. Google emphasizes excellent text rendering, multi-image composition (blend many images into one), and integration with broader Gemini capabilities (search grounding, locale-aware translations, and enterprise workflows in Vertex AI). Nano Banana Pro aims to be production-ready for designers who need high fidelity and predictable text layout inside images.

What is Qwen-Image?

Qwen-Image (from the Qwen/Tongyi family) is an image model released by Alibaba that has been evaluated across academic and public benchmarks. The Qwen team’s technical report documents strong cross-benchmark performance (GenEval, DPG, OneIG-Bench) and highlights particular strengths in prompt understanding, multilingual text rendering (notably Chinese), and robust editing. Qwen-Image is often discussed as one of the leading open-source / enterprise-friendly options outside the US hyperscalers.

Head-to-head: where each shines

  • GPT Image 1.5 (OpenAI) — Strengths: fast generation, strong instruction-following in multi-step workflows, well-integrated ChatGPT UX, and broad API accessibility. Early benchmarks place it at or very near the top in combined generation & editing metrics; OpenAI’s presentation focuses on the model as a “creative studio” for practical productivity.
  • Nano Banana Pro (Google) — Strengths: exceptional text rendering and enterprise integrations (Vertex AI, Google Workspace), strong localization and multi-image composition features, studio-grade controls for angle/lighting/aspect/2K output. Google emphasizes the model’s utility for marketing/localization pipelines and precise poster/mockup generation.
  • Qwen-Image (Alibaba) — Strengths: cross-benchmark performance across international datasets, open technical reporting, and strong multilingual text rendering. It represents a compelling choice for developers and enterprises focusing on Asian markets and teams seeking transparent benchmark results.

Practical differences developers will notice

  • APIs & integration patterns: OpenAI exposes GPT Image 1.5 through the Image API and the Responses API; Google exposes Nano Banana Pro via Gemini/Vertex; Alibaba publishes model docs and demo endpoints. Pricing and rate limits differ across providers and will affect production costs and throughput decisions.
  • Control vs. speed trade-offs: Some providers offer “fast/flash” modes vs “thinking/pro” modes — e.g., Nano Banana (fast) vs Nano Banana Pro (thinking). OpenAI’s messaging suggests GPT Image 1.5 reduces the practical need to trade quality for speed, but cost/performance tuning will still matter for bulk generation.

How to access and use GPT Image 1.5

There are two ways to access GPT Image 1.5:

ChatGPT (UI) — GPT Image 1.5 powers the new ChatGPT Images experience (Images tab). Use it to generate from text, upload images and make edits, or iterate interactively.

API — Use the Image API (/v1/images/generations and /v1/images/edits) to generate and edit images with gpt-image-1.5. Responses are base64-encoded images for GPT image models.

The good news is that CometAPI has integrated GPT-image 1.5 (gpt-image-1.5) and offers a lower price than OpenAI. You can use CometAPI to simultaneously use and compare Nano banana pro and Qwen image.

What are practical use cases and recommended workflows?

Use cases that benefit most

  • E-commerce & product cataloging: create many consistent product photos from a single specimen, change backgrounds, and keep lighting/facets consistent across images. GPT Image 1.5’s edit stability helps here.
  • Ad creative & rapid iteration: faster generation reduces cycle time for A/B creative variants.
  • Photo retouching and localization: swap props or outfits while keeping model identity consistent for regionally localized campaigns.
  • Design prototyping & concept art: the model supports both photoreal and highly stylized outputs, useful for early-stage concept exploration.

Who benefits most from GPT Image 1.5?

  • Content creators and social media teams who need fast, iterative editing and creative transformations.
  • Designers and product teams prototyping UI/UX assets, hero images, or advertising mockups that require rapid drafts.
  • E-commerce teams performing product mockups (clothing try-ons, background swaps, copy overlays).
  • Developers building conversational, image-driven experiences (e.g., chat-based photo editors, marketing automation).

Suggested workflow for creators

  1. Prototype in ChatGPT Images to refine instructions (use presets to discover styles).
  2. Pin a snapshot in API usage for production stability (gpt-image-1.5-YYYY-MM-DD).
  3. Run controlled A/B tests comparing model outputs and human post-processing costs.
  4. Integrate moderation checks and a human-in-the-loop for brand or safety-sensitive tasks.

Cost and performance considerations

Faster generation can reduce latency and (depending on pricing) cost-per-image, but enterprise usage should measure both throughput and token/compute pricing.

Safety, bias, and hallucination

GPT Image 1.5 reduces certain failure modes (bad edits, inconsistent faces) but does not eliminate hallucinated or biased outputs. Like other generative models, it can reproduce cultural biases or produce inaccurate depictions if prompts are poorly specified. Implement guardrails: content filters, human review, and test suites that reflect expected edge cases.

Conclusion — Should you try GPT Image 1.5?

If your project needs high-quality image generation or robust, iterative editing within conversational workflows (for example: marketing creatives, product mockups, virtual try-ons, or an image-enabled SaaS pro.

DEV Track Spotlight: The Builder's Job Is Not to Build: A Mindset for Better Outcomes (DEV347)

2025-12-21 23:30:03

Builders often define themselves by what they create and the tools they use. It's natural - after all, that's where we spend our time and direct our focus. But what if this attachment to building is actually getting in the way of our primary job: solving problems?

In DEV347, Ben Kehoe, Distinguished Engineer at Siemens and AWS Serverless Hero, delivered a thought-provoking session that challenges how we think about being builders. His central thesis: "A builder's true job is solving problems, which may or may not require building something."

Watch the Full Session:

The Problem with Traditional Builder Mindsets

Ben identified three common mindsets that can limit our effectiveness:

Identifying with your tools - Whether it's VI versus Emacs, SQL versus NoSQL, or any other technology choice, when tools become part of our identity, disagreement feels like a personal threat. This leads to flame wars and poor decision-making.

Identifying with your output - When we view our code as "our baby," not-invented-here syndrome takes hold. If someone suggests our creation isn't useful, it feels like an attack on ourselves.

Isolation from greater purpose - When we narrow our focus to just delivering to the next team without understanding the broader organizational context, we lose sight of why customers would care about our work.

These mindsets share a common problem: they focus on outputs (the things we build) rather than outcomes (the problems we solve).

Why Mindset Matters: Lessons from DevOps

Ben drew powerful analogies from software development practices to illustrate why examining our mindset is valuable:

Continuous Deployment - The value isn't just faster time to market. It's that continuous deployment forces you to be good at testing, rollback, and mean time to resolution. It creates accountability and requires humility - you're acknowledging you won't get it perfect, so you need robust safety mechanisms.

You Build It, You Run It - When the same team is responsible for both development and operations, they're held accountable for software quality. If it's hard to run, that's their problem to solve.

Blameless Postmortems - We don't assign blame not because there's nobody to blame, but because blaming people prevents us from understanding why things went wrong. We prioritize introspection over finger-pointing.

As Ben noted: "Humility and self-confidence are not mutually exclusive. Humility and ego are." Self-confidence means believing in your abilities while remaining open to being wrong and always improving.

The Outcome-Focused Mindset

Ben's core argument centers on a crucial distinction: outcomes are assets, implementations are liabilities.

"When we talk about a software feature, the feature is the asset, but the implementation is a liability. At best, in a perfect world, it does exactly what you expect it to do. The only thing your implementation can do is subtract value from the feature."

This reframes everything. Every line of code you write is a potential source of bugs, maintenance burden, and technical debt. The feature itself - the problem it solves - is what has value.

This perspective also helps us understand our place in the organization. When you focus on outputs, you only see the next step in the value chain. When you focus on outcomes, you can trace how your work connects to customer needs through multiple teams and layers.

Ben referenced the classic saying: "People don't buy drills, they buy holes." Understanding the outcome (the hole) rather than just the output (the drill) allows you to work with customers to find better solutions than what they initially requested.

Applying the Outcome-Focused Mindset

Technology Selection

View tools as means to an end - Don't identify with your technology choices. Understand yourself as adaptable. If your dev setup has to be exactly right or you can't work, that's brittle - and we don't want brittle systems.

Focus on total cost of ownership - The AWS bill is only part of the cost. A system that runs cheaply but requires constant operational attention may be more expensive than one with higher infrastructure costs but minimal maintenance. Consider costs across you, your team, your organization, and your company.

Optimize for runtime over development time - Code runs far more often than it's built. Optimize for ongoing maintenance and operations costs rather than development speed.

Understand technical debt strategically - Ben made a brilliant point: if you ask your finance team whether your company should have zero debt, they'll say no. Debt is leverage. The same applies to technical debt. "If you have none of it, you are not moving fast enough." Take on technical debt strategically when it provides value, but have a plan to pay both the interest (keeping it running) and the principal (fixing it properly).

The Productivity Paradox

Here's an uncomfortable truth: "The feeling of productivity is a poor proxy for actual productivity."

When you're in flow state writing code, that feeling is about your outputs - how effectively you're creating code. But whether that code is the right thing to create isn't something you feel in the moment.

Ben shared a story about AWS Step Functions in 2017. Back then, Step Functions was hard to use - writing JSON, wrestling with JSONPath, poor documentation. It felt unproductive and frustrating. But if you spent that afternoon struggling with it, you often ended up with something you never had to touch again. It just worked, scaled automatically, and ceased to occupy mental space.

Compare that to building the same workflow in a different way that felt more productive in the moment but required ongoing maintenance, updates, and occasional firefighting. The total cost of ownership was much higher, even though it felt better to build.

Technology Transformation

Throwing away code should be a joyous act - When a feature is no longer needed, or when a third-party service or AWS service now does what you built, celebrate. That implementation was always a liability. Now it's off your balance sheet and you can create something else valuable.

This requires not identifying with your output. That code you poured blood, sweat, and tears into isn't you. If it's no longer useful, let it go and do something else useful.

Organizational Transformation

When your organization changes - through reorgs, new strategies, or different ways of working - understanding your place through outcomes rather than outputs makes you resilient.

If you're not your tools, then changing what tools you use or what you're building doesn't threaten your identity. You can understand how you're serving the organization in new ways, potentially moving up the value chain or into different value chains entirely.

The AI Factor

Ben addressed the elephant in the room: how does AI change this mindset?

Accountability still lies with you - Currently, if AI gets it wrong, you're accountable. This means you need to know what good looks like to catch and fix problems.

Apply the same thinking to AI-generated code - If AI is generating boilerplate, ask why that boilerplate is necessary. Reducing boilerplate means less code that can be wrong, whether written by humans or AI.

The senior/junior engineer gap - Historically, new technologies allowed junior engineers to compete with senior engineers by eliminating things seniors had to worry about. AI works differently. It's more effective in the hands of senior engineers who can evaluate its output and fix problems. Junior engineers using AI may not develop the skills they need because AI is doing the work for them. This creates a training challenge we must address.

Quality versus cost curves are shifting - AI can create something that works at extraordinarily low cost (vibe coding). But for very high-quality software, AI lowers costs much less dramatically. This changes business decisions about acceptable quality levels. "High quality software is not the point." The appropriate level of quality is a business decision based on needs, not an absolute standard.

Key Takeaways

We are not artisans - Software isn't craft work requiring perfection. It's easy to make software (though not easy to make good software). We're not creating objects of beauty; we're solving business problems.

Focus on outcomes over outputs - Features are assets. Implementations are liabilities. The less you have to build to achieve an outcome, the better.

Don't identify with your tools or output - You are not your technology choices. You are not your code. These are means to an end.

Understand total cost of ownership - Consider all costs: development, operations, maintenance, opportunity cost. Balance them intelligently.

Be strategically comfortable with technical debt - Like financial debt, technical debt can be leverage. Use it wisely.

Embrace change and obsolescence - When your code becomes unnecessary, celebrate. When the organization shifts, adapt by focusing on the outcomes you provide.

Builders are problem solvers - The thing that makes us builders is that our mechanism for solving problems is to build. But building is the tool, not the job.

As Ben concluded: "When we ask who am I, and we acknowledge that we are not our tools, that we are not our output, we can answer that we are problem solvers. That is the thing that we do. We are asked to solve problems in interesting ways. The thing that makes us different from other people, where we get that label, is that the mechanism by which we solve problems is to build, and that is what makes us builders."
