GPT-6 Astra Is Now Generally Available in GitHub Copilot

The flagship GPT-6 Astra model has landed in GitHub Copilot as a general-availability release. The model is designed for long-horizon, autonomous coding work — the kind of task that spans many files, many decisions, and many rounds of self-correction. For developers, that means the most capable coding agent OpenAI has shipped is now reachable from the editor surface they already live in, without a separate harness.

Meta Puts AIRA₃ Into a Live Kaggle Competition

As a test of its autonomous AI research system, Meta entered AIRA₃ into a live Kaggle competition run by NVIDIA — the challenge was to fine-tune a 30B Nemotron model and teach it to reason.

Lyria 3.5 Arrives in the Gemini App

Google's best-sounding music generation model is now available in Gemini, with more expressive vocals and richer output. Early testers say it can be prompted almost like a text-to-speech model, producing surprisingly natural phrasing.

Pricing · Ollama

DeepSeek-V4 Models Go Half Price Off-Peak on Ollama

DeepSeek-V4-Flash and DeepSeek-V4-Pro are now half price outside 12:00 to 18:00 UTC on weekdays — 5 a.m. to 11 a.m. Pacific — and all day on weekends. It is a rare structural move in a market that usually cuts list prices across the board, and Ollama says off-peak pricing will roll out to more models soon. The bet is simple: shift demand into idle capacity, and make frontier inference cheap enough to become a background habit.

“The fact that Astra can make me whatever fun little game I can imagine — and I can be playing it a few minutes later — is so cool.”

Astra Now Tops the DeepSecBench Leaderboard

On Vercel's DeepSecBench, Astra is now the best vulnerability-finding model in the world. It finishes in 49 minutes what previously took Sol roughly four hours, at nearly the same cost, with a better score — and comes in about 50% cheaper than Claude Opus 5 max. The benchmark measures how well a model finds real security flaws in application code, combining recall and precision into a single aggregate.
