OpenAI today updated its most popular ChatGPT model, debuting GPT-5.3 Instant. GPT-5.3 Instant is supposed to provide more accurate answers and better contextualized results when searching the web. The update also cuts down on unnecessary dead ends, caveats, and overly declarative phrasing, plus it has fewer hallucinations.
According to OpenAI, it tweaked the Instant model to address complaints about tone, relevance, and conversational flow, which are issues that don't show up in benchmarks. GPT-5.2 Instant had a "cringe" tone that could be overbearing or make unsubstantiated assumptions about user intent or emotions. The new model will have a more natural conversational style and will cut back on dramatic phrases like "Stop. Take a breath."
Users found that GPT-5.2 Instant would refuse questions it should have been able to answer, or respond in ways that felt overly cautious around sensitive topics. GPT-5.3 Instant cuts down on refusals and tones down overly defensive or moralizing preambles when answering a question. The model will no longer "over-caveat" after assuming bad intent from the user.
GPT-5.3 Instant also provides higher-quality answers based on information from the web. OpenAI says that it is able to better balance what it finds online with its own knowledge, so it is less likely to overindex on web results.
GPT-5.3 Instant is available to all ChatGPT users now. Updates to Thinking and Pro will come in the future.

The new Studio Display XDR is designed for all kinds of professional work, and it is uniquely suited for use in the medical field.
The Studio Display XDR supports DICOM medical imaging presets and a Medical Imaging Calibrator so it can be used for diagnostic radiology. Radiologists will be able to view images right on the Studio Display XDR without the need to use a single-purpose medical imaging display.
There is a display mode switching option for transitioning from a standard viewing mode to a radiology viewing mode. Pricing on the Studio Display XDR starts at $3,299, and it is more affordable than many specialized medical imaging monitors.
Apple says the Medical Imaging Calibrator that it created for the Studio Display XDR is pending FDA clearance and it should soon be available in the United States.
According to Apple, its aim with the new functionality is to continue to improve technology available to the healthcare community to boost patient care.
The Studio Display XDR also features a mini-LED backlight with 2,304 local dimming zones, 2000 nits of peak HDR brightness, a 1,000,000:1 contrast ratio, a 120Hz refresh rate, and advanced color accuracy.
Pre-orders for the Studio Display XDR will begin on Wednesday, March 4 at 9:15 a.m. Eastern Time, with a launch to follow on March 11.

If you still have a Mac with an Intel chip inside, you're not going to want to pick up one of the new Studio Display or Studio Display XDR models.
According to Apple's list of compatible Macs, neither model will work with an Intel-based Mac. Apple says that the Studio Display is compatible with a long list of Macs dating back to 2020, but they all have M-series chips inside.

The new Studio Display XDR features a mini-LED display with up to a 120Hz refresh rate, but you'll need a newer Mac to get support for the full 120Hz.
According to Apple, Macs that have an M1, M1 Pro, M1 Max, M1 Ultra, M2, or M3 will only support the Studio Display XDR at 60Hz. All other features remain available.
For the full 120Hz refresh rate, you'll need to have a Mac with one of the following chips:

As part of its environmental efforts, Apple says its new Studio Display and Studio Display XDR boxes feature a collapsible design.
Apple says the boxes can be broken down into smaller pieces that fit in most recycling bins:
Studio Display has been engineered to reduce its environmental impact. The stand is made with 100 percent recycled aluminum. The standard glass display contains 80 percent recycled glass — an Apple first. And the 100 percent fiber-based box has been extensively redesigned for collapsibility, allowing it to be broken down into smaller pieces that will fit in most household recycling bins.Apple also says both of the new Studio Display models contain 80% recycled glass, which is described as an "Apple first." This feat applies to models with standard glass, not the upgraded anti-reflective, nano-texture glass.

Apple today provided the third beta of an upcoming macOS Tahoe 26.4 update to developers for testing purposes, with the update coming a week after Apple seeded the second beta.
Developers can download the macOS Tahoe 26.4 update by opening up the System Settings app, selecting the General category, and then choosing Software Update. Beta Updates will need to be enabled, and a free developer account is required.
macOS Tahoe 26.4 adds a new Charge Limit feature so Mac users can select a maximum charge level that ranges from 80 to 100 percent. Apple also brought back the Compact tab layout in Safari for those who missed the option in earlier versions of macOS Tahoe.
Apple silicon Macs who are running apps that still rely on Rosetta will see warnings about the upcoming end of support for Rosetta. After macOS Tahoe 27, Apple will phase out Rosetta support, and all apps will need to be updated before that time.
macOS Tahoe 26.4 will be released to the public in the spring after several weeks of beta testing.
