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

A video post showing a DevDay hype reel made with GPT-6 Astra Pro, presented as a showcase of the model's video generation.

The GPT-6 Astra Challenge run by Product Hunt and OpenAI Devs has wrapped up, with 5 teams splitting $10k in API credits.

The post quotes Altman saying he runs thousands of GPT-6 Astra agents every night and monitors them from his phone, and teases a live demo an hour later.

Because GPT-6 Astra burns through tokens heavily, the author cut AGENTS.md from 261 lines to 10 and added a nightly flow that automatically audits the configuration.

The author jokes that Meta's muse agent lifted CPU stocks and OpenAI's GPT-6 Astra pulled memory stocks up, arguing that half a year after the agent paradigm took hold, infrastructure stocks are benefiting first.

The author uses SmartUV, TextureGen and the new rigging to fix misplaced textures and add finger animation, then has Astra imitate a dance from a video, with a finished clip attached.

The MacStories author says GPT-6 Astra first built a testing harness for local AI, then used Computer Use and remote connections to orchestrate two Macs and one PC through about 140 local model runs in three days.

On the latest Intelligence Index, Astra leads at 53 ahead of Opus 5.2 and Fable 5.1 at 51 and 50, with Sol, Qwen3 Max, GLM-5.3, Grok 4.8 and others clustered in the 40s.

The author outlines steps for giving ChatGPT Astra article prompts, website access, a Google Business Profile and competitor data, claiming it can replace a $10,000-a-month SEO agency.

The author uses GPT-6 Astra with Fable 5.1 for 3D modeling, with MeshyAI and the Godot engine mentioned in some parts.

The author argues OpenAI's moon, earth, sun and star naming already implies a hierarchy: Sol will likely be faster, cheaper and sufficient for most uses, but less capable than Astra.

The author argues agents fail because developers treat the conversation as a database, and proposes compressing history, limiting tool calls and keeping only the goal, decisions and next action.
