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

In the video Sam Altman says he runs a few thousand GPT-6 Astra agents each night, monitored from his phone, and the post frames the shift as one person managing an entire AI workforce.

TokenGremlin says Astra is already in the frontier tier but too expensive, expects GPT-6.1 Astra to be stronger, and believes OpenAI is more focused on the rumored Fable 5.5, said to be stronger than Opus 5.5.

A demo shows Astra producing a 3,412-piece jet engine explosion and reassembly animation purely by writing code, with no video tool.

A blogger jokes that GPT-6 Astra fell out of favor a day after launch, and says hands-on testing shows Claude Opus 5.5 is more durable and slightly stronger than GPT-6.

A leaker reconciles two accounts: OpenAI knew Opus 5.5 would be strong but was caught off guard by how strong it turned out, which increased the urgency around 6.1 Astra.

A developer open-sourced Chat On Steroids, a coding agent built on ChatGPT that can read and edit files, run commands and tests, split tasks across multiple agents, and uses ChatGPT quota instead of Codex quota.

The author believes OpenAI was surprised by Opus 5.5, already has significantly stronger models internally, and may prioritize releasing GPT-6.1 Astra or even a "Bel" model, possibly at DevDay.

A rumor claims Astra Minor is OpenAI's competitor to Opus 5.5, that it is the new Sol, that Sol becomes the new Terra, and that the Terra line would go away.

A developer shows progress on a GPT-6 Astra character animation tool with hit/hurt boxes and ragdoll physics, aiming for a 1v1 Dark Souls-style demo in the browser using ThreeJS and WebGPU.

BridgeBench gave four models the same prompt to build a lava lamp, and GPT-6 Astra finished in 5m 4s for $0.63 versus Claude Opus 5.5 at 9m 35s for $1.27.

A long video tutorial on giving Codex your context, turning repeat work into scheduled skills, delegating jobs by voice from your phone, and editing reels and repurposing long videos.

The author put GPT-6 Astra and Claude Opus 5.5 into two Unitree G1 robots inside a MuJoCo ring fence to push each other out, and Astra won after 31 seconds.
