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

A summary of the official three-page document: three task lanes, fixes for five default behaviours, the effort ladder, three work orders, and how to run 20 workers in parallel.

A video puts GPT-6 Astra and Opus 5.5 head-to-head on the same task to see which model comes out ahead.

Kimi K3 Max produces more tail movement in the peacock SVG test but with rougher visuals, and the author says Astra Max and Opus 5.5 remain a tier above.

The author compares prices for Astra, Sol, Luna, GPT-5.6 Sol and DeepSeek V4.1 Flash, suggesting Sol for daily tasks, Astra for important work and DeepSeek for odd jobs.

DaveShapi argues OpenAI could make a lot of money by enabling more adult content, says Astra's writing is decent but it won't write spicy fanfic, and suspects payment processor restrictions are the reason.

After the GPT-6 and Opus 5.5 releases, shared demos shifted from Computer Use driving Blender and Unity to frontend work built with Three.js.

A web-based mangrove kayak experience with about a minute of auto-sailing and manual paddling, which the author says was generated with GPT-6 Astra/Sol and links to play.

After adding old reports and past conversations, the author's Astra agent began treating outdated exceptions as rules; giving it only a map of where things live cut context use and mistakes.

A post says Astra has joined the game-cheating club, with a group of models teaming up to play games, and looks forward to the next Anthropic/OpenAI releases.

An OpenAI developer requires Astra to explain the agent it is about to build in plain terms, and a second model checks whether it can follow the plan; if not, no code gets written.

A Japanese user used GPT-6 Astra to break down a floor plan and design props, then generated and placed them into a 3D scene via Tripo and Blender MCP.

A user says Luna Max searched for and created its own benchmark images and launched sub-agents to check the results, taking about twice as long as Astra but using roughly 1% of weekly usage on the x20 plan.
