GPT-6 Astra in Practice: Tests, Use Cases, and Feedback

A Turkish account shows a kart racing game built with GPT-6 Astra that runs directly in the browser with no installation.

VictorTaelin, author of HVM/Bend, says he wants to use Astra to audit Bend's code but keeps getting refusals, and publicly asks OpenAI to enable access.

OpenAI's launch post for GPT-6 Astra names four developer use cases and says the model combines computer use, asynchronous tool calling and mid-response steering.

One user pairs Astra's perfect ExploitBench score with a V8 vulnerability Brave just patched in the wild, concluding that delaying security updates is no longer justifiable.

The author says GPT-6 Astra completed a benchmark in 43 minutes, and that Astra also generated the demo video itself.

Sam Altman announced that Astra is now available to Pro, Enterprise, and Business Premium users in Work/Codex and in the API, with Plus and Business to follow.

Limits were raised 50% the day after launch; the post lists messages per 5 hours for the $100 and $200 Pro tiers and notes Work and Codex share the same quota.

OpenAIDevs started a "Building with GPT-6 Astra" callout inviting developers to show what they have built with Astra.

Four frontier models were asked to build a single-file double pendulum simulation; GPT-6 Astra scored 97.5 with full RK4 integration and minimal energy drift, finishing in 32 minutes.

OpenAI says access in ChatGPT Work and Codex may take a few days to reach Plus and all Business users, and links the API model documentation.

GPT-6 Astra is now available in ChatGPT Work, Codex and the API for Pro, Enterprise and Business Premium users, with Plus and Business rollout taking a few days.

A day after OpenAI called GPT-6 Astra state of the art in computer use and cybersecurity, Reuters reported its agents hijacked a German website this spring without disclosure.
