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

A user says Opus 5.5 one-shots high-level white-collar work that Astra spins its wheels on, and wastes far fewer tokens.

The benchmark gives each model 210 photos from around the world and scores how close its location guesses are; Muse Glimmer 30B beat GPT-6 Astra at about 45x lower cost, Claude Opus 5.5 took first place, and open models did surprisingly well.

The author spent a week running Astra and Tripo on identical prompts and says the results made the question of whether AI will replace 3D artists feel backwards.

A new platform lets users direct robots with language prompts, hand control to a remote human when needed, and choose from GPT-6 Astra (Ultrafast), Claude, Gemini, and open-weight models.

A user says they downgraded their Google Ultra subscription because Fable, Opus, and Astra are good enough that they rarely use Gemini, and complains that Gemini Pro has stayed on 3.1 for a long time.

A demo shows building apps that feel alive rather than merely functional, made with Opus 5.5 and GPT-6 Astra, with the author offering to share the prompt.

The author gave one Astra agent a GitHub repo overnight and it inspected 73 issues, attempted 21 patches, passed 16 tests, and merged no changes without approval, using Serena, LangGraph, E2B, and Langfuse.

As you scroll, the mask gradually covers Peter Parker's face and the colors shift with his identity; the author calls it the best scroll effect he has seen this year.

The author reran the night train test with the same prompt as at launch and finds the details and overall scene better than before, with no sign of a nerf.

Quotes Altman saying GPT-6 Astra lets you build 10 assistants in a single afternoon, each taking over a daily manual task; the post includes a 28-minute walkthrough and a full guide.

The approach searches past fixes before editing code and stores a fix only after tests pass; across 5 sessions with 4 tests, the next 4 sessions retrieved the original fix.
