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

Researchers including Max Planck found agents often finish early and then idle; on-time rates were 63% for Astra, 39% for Sol and 4% for Fable 5.1, and AI tends to overestimate its own task time.

A developer shares updates on a Codex hardware build, steering GPT-6 Astra toward his preferences while Codex handles CAD and build documentation, and gives a size reference for the robot.

The author used GPT-6 Pro with Astra to read official program PDFs from all 47 prefectures and rank the free-choice composers chosen by 418 high school entries.

A comparison post pairs Claude Opus, Sonnet and Haiku 5.5 against GPT 6 Astra, 6.1 Sol and 6 Luna, claims Claude wins every matchup and dares others to argue back.

Elliot Glazer says he had Astra check an OpenAI paper on algebraicity of Weil classes after a tip, and one of its non-formalized results appears to be flawed.

The author shows a Three.js creek 3D experience generated with GPT-6 Astra and modeled in Blender, running directly in a browser.

A Japanese post lays out how Pro, Plus and Free tiers map to GPT-6 Sol, Astra and Luna in chat, and notes Plus users can still explicitly pick Astra in Codex.

The author gave Opus 5.5 and GPT-6 Astra the same prompt to each generate a small resort, comparing palm trees, water detail and API cost.

In the first StarSkirmish Hillclimb, GPT-6 Astra beat Claude Opus 5.5 to take first place, finishing the whole run in 43 hours.

The poster argues ordinary users don't want to pick models, credits Tibo's steady iteration, but says Claude and Grok Bot subscriptions are currently better value.

A user estimates that running Astra for about three hours per problem to solve decade-old math questions costs roughly $800 at API prices, which would fit inside a $500 monthly subscription.

The author used the unreal-home-wizard skill with Codex (GPT-6 Astra and Luna) and Blender to turn a single room image into a walkable Unity 3D scene, then added a sliding door and a connected second room.
