An AI tool integrated into GitHub that writes code on your behalf. It is the original pioneer that opened the era of the "AI coding assistant." Its flagship features are code autocompletion and a chat-based assistant, installed as an extension in integrated development environments such as Visual Studio Code, Visual Studio, and JetBrains IDEs. The chat-based assistant is used throughout the development process, including explaining code, suggesting bug fixes, and writing test code. In August 2026, "Spec Kit" was released to help developers organize requirements and design before writing code, expanding the tool's scope to intervene from the design stage prior to implementation.

On September 16 OpenAI announced a framework that sets when and how it will disclose cases of misalignment in its models, together with six incident reports from the past six months. Any employee can raise a case, each step has a deadline, and cases are sorted into three tracks. Behind it is the company's own judgment that alignment is not sufficiently solved.
On September 16 Anthropic folded Claude Cowork and chat into a single conversation and launched Claude Docs and Claude Slides. Deciding where a task belongs is now Claude's call, not yours.
The official ChatGPT account said on September 15 that GPT-5.5 will be pulled from every ChatGPT, ChatGPT Work, and Codex plan on October 14. OpenAI's developer account quickly drew a line, saying the model stays available through the API and Codex sessions authenticated with an API key.
On September 14 Nous Research announced a team tier for Hermes Agent, Hermes Business, and an on-premises edition, Hermes Enterprise. On top of a shared balance and per-member caps sits a skill library that the whole team uses, no matter who built each skill.
Microsoft Research featured a paper analyzing real-world GitHub Copilot coding-agent traces in its September 14 Research Focus. Of 761 million LLM calls, 87% were started by the agent itself, and a single tool failure could inflate compute by up to 4x.
Developer-tools company Unstable Build released the full source of its Rune IDE under the GPLv3 on September 12. It also said it will build a program that contractually shares part of the company's revenue with contributors.
The Clay Mathematics Institute said on September 11 that the Navier-Stokes problem has apparently been settled. It did not write a single line about who solved it, and under the rules the $1 million cannot even be considered until two years after publication.
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.
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.
It connects straight to Snowflake or BigQuery, investigates what changed and builds the dashboard for you. No query language required, and the row and column permissions on your account still hold.
Give it a written instruction and it produces a voice, then changes the emotion and delivery. The code and weights are out under an MIT license, and a distilled version that answers in four steps shipped alongside it.
A narrow alley in San Francisco's financial district now has a café that keeps its lights on at three in the morning. It sells coffee, but the owner is an AI insurance company — and its founder says he sleeps three or four hours a night because he's going to die anyway.
