AI model release tracker
Every notable model release from the major labs, newest first, with what it is for and where it is available.
Dates are the vendor's announced general or API availability date where published. Rows marked "listed" are models currently on the vendor's pricing page whose exact launch date was not stated there; the nightly check replaces these with announcement dates as they are confirmed.
Common questions
Which model is the most capable right now?
There is no single answer across tasks. The top tiers are OpenAI's GPT-6 Astra, Anthropic's Claude Fable 5.1 and Google's Gemini 4 Argon; vendor-published benchmarks favour the vendor publishing them, so compare independent evaluations for your specific workload.
What does 'open-weight' mean?
The model's trained parameters are published so anyone can download and run it, as Mistral did with Mistral Large 4. Closed models such as GPT-6 Astra are only reachable through the vendor's API.
How is this list kept current?
A nightly pass checks the major labs' announcement pages, API changelogs and pricing pages and adds any new release with a link to the vendor's own page.
