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

A Japanese post claims GPT-6 Astra was trained on about 100,000 Grace Blackwell NVLink72 units with plans to scale to 400,000, and jokes that Google should use Nvidia too.

A comparison says Astra Max ran for over 40 minutes on a Supabase integration task within a $20 budget, while Opus 5 would have lasted 20 minutes for the same price.

After testing GPT-6 Astra over a weekend, the author says Fable 5.1 reasons more coherently and misses fewer material points on traditional equity research tasks, calling Astra a good starting point.

In a computer-use game of skribbl.io, GPT-6 Astra reached a score of 1465 against Claude Fable 5.1's 300.

A video shows GPT-6 Astra zero-shot directing a robotic arm to sort irregularly shaped blocks by color into cups in 15 minutes, as a benchmark for turning language into physical action.

A short reaction meme joking about how Claude Fable 5.1 would react to someone using the new GPT-6 Astra.

Someone used a single Astra prompt to generate a playable Pokémon remake, with a video showing the fidelity, and questions whether buying games still makes sense.

The author gave the same prompt to Fable 5.1 and GPT-6 Astra and compares which did better in a video, with the prompt in the comments.

A creator connected Codex to Blender MCP to set the art style, then built a 60fps 3D game in pure three.js with no external assets in 45 minutes.

A Brazilian user says Astra used MCP to automatically build the entire city of New York inside Minecraft, and calls it a sign AGI is at the door.

A Japanese developer says Astra, after finishing a game development task, made a before-and-after comparison video of the changes on its own, saving manual review.

An Iranian developer used Astra to build a Safari extension that converts Persian web fonts to Vazirmatn, after waiting two years for a Chrome version to come to Safari.
