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

A roundup of the day: Anthropic releases Claude Sonnet 5.5, OpenAI's DevDay teaser points to Codex features, and the WSJ says GPT-6.1 Astra was pulled over safety and alignment.

The author argues that Sol and Luna's halved prices offset the halved usage, so the real reduction falls on GPT-6 Astra, and asks why Astra isn't given its own smaller weekly limit like Anthropic does with Fable.

The author gave GPT-6 Astra a simple brief to generate JoJo-inspired boxing visuals, then animated them with Seedance 2.5 via Pollo MCP, with the prompt included.

A Japanese user's previously abandoned 3D model of an umbrella that opens and closes was generated successfully in one attempt with ChatGPT Astra in Autodesk Fusion.

The author had multiple research agents cross-check the same question, left conflicts unresolved, and kept only conclusions traceable to original evidence.

The author posts a video testing three models on the same prompt and says GPT-6 Astra's output is hard to make sense of.

A Korean user used GPT-6 Astra to put together a monthly checklist in Google Sheets, which others can copy for their own use.

The post notes OpenAI has already released GPT-6 Astra, Sol, Luna, GPT-Live-1 and GPT Images 2.5, and wonders what DevDay could still announce.

The author argues the "o" hints point to the always-on assistant dots rather than a model, that Astra 6.1 is ruled out, but that OpenAI won't hold its biggest DevDay with no new model at all.

The author says Opus is cheap and plentiful while Astra is scarce even on the Pro plan, and plans to downgrade unless OpenAI offers much larger limits.

A Russian-language post describes a prompt technique of telling GPT-6 Astra that Claude handled the same task better, which users say pushes it to produce usable results.

The author uses GPT-6 Astra on the $200 plan as the main model, alongside Grok, Moni, Elfa and other APIs, to push a nightly digest of AI, chip, robotics and onchain news to Telegram.
