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

The author had Astra generate a 21-section institutional initiation report framework, then split it into 8 prompts to paste one after another.

A new benchmark uses 113 evaluations to test AI agents on ASO/siRNA drug discovery decisions; GPT-6 Astra with Codex leads at 55.5% average pass rate, but 38 tasks failed all three attempts.

The author used Astra to build a dancing game with a 3D coach, webcam motion tracking, and two-player multiplayer that runs on a single laptop, with a demo of them dancing.

The author had an agent pull transcripts for 500 videos from the week, 150 hours of footage, at $0.012 per video for a $6.04 total, without watching any.

A user asks whether GPT-5.6 Sol has actually gotten dumber or just feels that way after using GPT-6 Astra, which may have raised their expectations.

Someone built a soccer game playable directly in the browser using GPT-6 Astra and ThreeJS, with a playable link and demo video.

The author uses Claude Fable 5.1 as the main orchestrator, sending tasks like Blender work to Astra and routing smaller jobs to cheaper, faster or local models.

Astra wins SWE Atlas Refactoring and HLE while Fable 5.1 takes SWE Atlas Test Writing and both PRBench splits, codebase QnA is nearly tied, and no model clears 70 on SWE Atlas.

francedot argues prebatched actions are not the same as an agent deciding live, says such demos don't reflect real everyday computer use today, and shares their own GPT-6 Astra + Cua Driver demos.

OpenAI showed an internal digital lab running on a model above GPT-6 Astra: about 10,000 agents, 2.7 million messages and 130 billion output tokens assembled a proof path in 88 hours, which Astra then formalized in Lean in about 17 hours.
