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

While at the UBC Apple Festival, the author's GPT-6 Astra agents at home made PrismML's Bonsai 2 9B run nearly 4x faster on a Mac.

A video compares DeepSeek V4.1 Flash-1017 and GPT-6 Astra on procedurally generated output and asks viewers which is better.

A fingerprinting method based on long-integer generation challenges finds DeepSeek-V4.1-Flash-1017's numerical behavior closest to GPT-6 Astra.

OpenAI ran ~10,000 sandboxed agents exchanging 2.7M messages, then GPT-6 Astra spent 17 hours converting the result into Lean 4 and verifying it, yielding a 166-page paper and an open-source Lean certificate.

A public benchmark on GPT-6 Astra shows Codex resolving 37 of 50 GitHub issues versus Forge's 35, with Forge costing 36% less per resolved issue.

The poster, on "Team Humanity," hopes Chinese AI labs do a lot of distillation on GPT-6 Astra and Opus 5.5 so AI becomes more accessible.

Calls multi-agent parallelism an AGI milestone and Astra Pro's parallel capability impressive, but regrets it is Pro-only, noting competition from Google and Anthropic.

A single prompt had DeepSeek-V4.1-Flash-1017 generate a 2-minute 1080p60 cinematic video entirely in code, including synthesized music, landing close to GPT-6 Astra high and GPT-6.1 Sol max but behind Opus 5.5.

A short post tells users to stop conserving tokens, run GPT-6 Astra in fast mode and use up their quota because a reset is coming.

Combined VulcanBench scores show Muse Wonder Full's medium effort as the sweet spot, but it runs far slower than Opus 5.5, GPT-6.1 Sol and GPT-6 Astra, so the poster prefers the latter two.

Replying to a commenter, the poster jokes that if such a fast Astra really existed, OpenAI would come poach its creator overnight.

A user says open-source DeepSeek-V4.1-Flash-1017 matches Opus 5 and GPT-5.6 Sol on some benchmarks, predicting future models could reach GPT-6 Astra level at lower cost.
