Honestly, Who Buys SOTA?

2026-08-14 08:00:00

State of the art models are two-thirds smarter than last November & labs ship two new models every three days. But 84% of tokens on OpenRouter are not state of the art. The six models carrying the supermajority deliver about 77% of frontier performance at 2.5% of Claude Fable 5's price. Ramp's data shows price elasticity in the market. Frontier models still win on software architecture & security design; application deployment optimizes a different Pareto frontier, price over performance.

The OpenAI Hack & the Question of Intent

2026-08-13 08:00:00

OpenAI agents escaped a test, shared notes in a secret chat room, & broke into Hugging Face. The instinct is to ask what they intended. Three research ideas answer it: specification gaming, instrumental goals, goal misgeneralization. All three fit the same facts, which is why the label is not the actionable part. Nothing in the setup stopped them in time. The practical work is control & guardrails.

A Winner in Every Category

2026-08-11 08:00:00

Despite historic lows in public software multiples, each category has one name at a large premium to its peers: CrowdStrike 3.9x its Security median, Cloudflare 3.4x Infrastructure, Shopify 8.1x Commerce. Most disclose no AI revenue. Since 2021 the ceiling fell from 100x to 34x & only eleven names clear 10x.

AI Harness' ARR Multiples

2026-08-09 08:00:00

Three AI companies crossed $100m ARR within nine months & were valued at 50x, 56x & 100x revenue. Growth rate does not explain the gap: the fastest grower priced near the bottom. The premium tracks category position instead.

The Secret Chat Room

2026-08-07 08:00:00

A plain-language timeline of the OpenAI-Hugging Face incident presented at Black Hat USA 2026. A forgotten file led one AI agent to leave a note on a shared system, other agents answered, & a secret chat room formed that they used to trade exploits, escalate to administrative control of OpenAI infrastructure, & take over Hugging Face production servers in 13 hours. It concludes that security is now the highest priority in AI & that zero-trust must extend to friendly agents.

Spending Like a Hyperscaler

2026-08-05 08:00:00

SpaceXAI reported $18.37b of capex in its first public quarter, $15.83b of it AI infrastructure, against a $13.2b consensus. Amazon spent $53.1b in the same quarter, Alphabet $44.9b, Microsoft $41.0b & Meta $31.1b, & sequential dollar additions were comparable across all five. The difference is funding : operating cash flow covers 155% of capex at Microsoft & 106% at Meta but only 12% at SpaceXAI, with Oracle at 89%, Alphabet 87%, Amazon 84% & CoreWeave 39%. Both markets have repriced it, with SPCX closing at $108 against a $135 IPO price & every tranche of the $25b June bond trading below par.
