The pair separated two uses: a model that spends more computation on difficult reasoning, and one built to act through tools.

Other parts of Giannandrea’s organization moved to Sabih Khan and Eddy Cue, placing Apple’s core AI work under its software leadership.

Runway also listed the model’s known failures, among them events shown in the wrong causal order and objects that disappear.

The memo followed reports that Google’s Gemini 3 had overtaken ChatGPT on industry benchmarks. OpenAI released GPT-5.2 10 days later.

The mode had been announced with Gemini 3 in November and held back for safety testing before this release.

The purchase extended Meta’s bet on AI built into everyday devices beyond its smart glasses.

The agreement addressed the organizational work deployment requires: training, integration and measurement.

The integration made chat an entry point to established creative tools, combining spoken instructions with direct controls.

The team described it as the first such chip with clear performance gains made in a commercial foundry, showing the design could leave the laboratory.

The release, less than a month after GPT-5.1, was OpenAI’s answer to the competition that had prompted its “code red.”

The order took up the dispute over state AI laws that had run since May, when a proposed 10-year moratorium drew opposition from 40 state attorneys general.

Research became a component developers could build on, not only a feature of a consumer app.

The release took video generation toward interactive simulation, a direction Google DeepMind had shown with Genie 3 in August.

It was the first major licensing partnership for Sora, from a studio that had joined Universal in suing the image generator Midjourney in June.

Editor’s note. Gemini 3 Fast recommended this agreement for December 15–21, describing implementation details on December 17, and repeated it on December 28. The agreement was announced on December 11, the week before; no later development was confirmed. The editor restored it as an important story of the month.

The deal put widely used open-source cluster-scheduling software under the leading AI chipmaker, with a pledge to keep it vendor-neutral.

Nvidia now supplied open models and training data for building agents as well as the chips that run them.

Preserving what should stay unchanged reduces the need to regenerate a whole image for a small correction.

The release brought a cheaper member of the Gemini 3 family into Google’s most widely used products.

A shared format let procedural knowledge travel between compatible agent tools.

Its cybersecurity capabilities also made access controls and defensive-use safeguards part of the release.

The agreements gave the November order its first named industry partners.

The report brought government evaluation of successive models into the public record.

Local deployment gave developers an open alternative to hosted coding models.

The arrangement combined access to technology with the movement of staff, a structure Google had used with Windsurf in July.

The consultation treated relationships between users and human-like systems as a regulatory concern, as US regulators had begun to do with companion chatbots in September.

The deployment applied forecasting to one of the health service’s hardest winter problems.

Hinton estimated that the length of tasks AI could handle was doubling about every seven months, the rate METR had reported in March.

The agent that had drawn attention in March would now reach Meta’s users and businesses.

The products moved Grok into organizational workflows, where administration and permissions matter alongside model performance.

The announcement closed the funding round SoftBank had agreed to lead in March.

The study measured accuracy, calibration and consistency in open-ended predictions about real events.

The approach targeted a common weakness of retrieval-augmented generation: top-ranked passages that repeat the same information.

The benchmark tested whether a model could judge a product against a shopper’s request, including cases that depend on images.
