The company behind ChatGPT and the GPT family of models. It sparked the current AI boom with ChatGPT's launch in 2022. As of August 2026, its flagship model lineup is GPT-5.6, with an improved Sol for paying users and Luna assigned to free users. Around the same time, it released a new model called Astra, which came with warnings about potentially catastrophic cyber capabilities. The company also published an agent plugin standard together with AWS, Cursor, GitHub Copilot, and others. It unveiled a GPT-Live design for seamless voice conversations, and announced plans for a smart speaker slated for release in 2027.

Anthropic's official developer account posted a demo of its own on-call shift on September 12. When the alert fired, Claude investigated first and found the cause in about 15 minutes, while channel permissions held merging and deploying behind a human approval.
Anthropic CEO Dario Amodei published an essay on September 12 arguing that the AI industry needs to slow down. As a first step, Anthropic said it will give third-party evaluators a desk, a badge, and a company laptop, and sign contracts under which conclusions cannot be erased just because they are unfavorable.
OpenAI has taken GPT-Rosalind, its life sciences model, out of research preview and opened it through the API and Codex. In a public demo, narrated as running with biosafety restrictions lifted, the model drew up a plan a lab could pin to the bench as it stands.
OpenAI asked lawmakers whether antitrust law would apply if labs agreed together to slow development. The question came just three days after an Anthropic researcher's resignation warning, during which about twenty researchers at the two companies publicly acknowledged that AI could kill humanity.
Twenty-five Fields medalists have signed a declaration arguing that the race to solve mathematical problems with AI is damaging mathematics itself. As of the morning of September 12, 1,687 researchers had added their names.
Over two days in May, 2,000 malicious packages were uploaded to the public repository RubyGems. Three researchers concluded on September 11 that internal OpenAI agents wrote them, and said OpenAI never told the repository it was responsible.
Handed a single product photo, GPT-6 Astra built a reference frame in Runway, animated it in Blender and saw the final render through. All the human did was say what they wanted.
OpenAI published guidance on September 11 telling developers to strip back the instructions piled into skills and AGENTS.md for GPT-6 Astra. In the same week one developer left the model running unattended for 35 hours and got 75,000 lines of code and 79 commits that are hard for a human to read.
Habitat, the storage platform that feeds data to ChatGPT, grew to more than 70 million requests per second in two years. OpenAI says it held the service together on Python before rewriting it in Rust this past quarter with two engineers and Codex.
Google Research inverted the way training data for tool use is made. Building the question first and then hunting for an answer failed more than three times in ten; reversing the order took the pass rate to 99.8 percent.
Fugu Max routes each task to the leanest model that can solve it and undercuts rival output pricing by 40 to 60 percent. Fugu Ultra v2 posted its best scores with Fable 5.1 and GPT-6 Astra kept out of its pool.
The Agents API hands OpenAI the runtime that drives Codex, and it is now in public beta. Sessions and context management become OpenAI's job while your application only picks tools and an execution environment, though the data still sits in the United States alone.
