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

A Spanish-language post shares a full prompt that has GPT-6 Astra scan emails, documents, spreadsheets and meetings to list repetitive tasks AI could take over, plus the MCP setup for each.

The setup has Sol write code while Astra reviews only at three points — before planning, when the same error repeats, and before calling work done — with a Codex config prompt to paste.

A long-time user says GPT-6 Astra in Dots is more relaxed, jokes more and builds its own identity, with a very different feel from the Work/Codex version.

The developer argues OpenAI's new dots interface doesn't improve the model: instruction following and taste remain poor because the problem is the Astra/Sol base models.

A poll asking which model people use daily in Hermes Agent, with options including GPT-6 Astra/Sol, Opus 5.5, Grok 4.7 and DeepSeek V4.1 Flash.

A post counts over 50 AI model releases in September, including GPT-6 Astra, GPT-6.1 Sol and Opus 5.5, and asks which one people liked most.

A shared prompt for checking whether Codex has been degraded: pick GPT-6 Astra or Sol, disable web search and tools, and ask for the latest Python version as of March 2026.

Claude Opus 5.5 tops BridgeBench's front-end design ranking, Anthropic holds the top four spots, and GPT-6 Astra and Sol both miss the top 10.

Tibo said OpenAI gave Astra to its strongest engineers, who rewrote the inference stack to produce GPT-6.1 Sol, nearly as intelligent as Astra at a fifth of the price.

The author says a proof originally produced by GPT-5.6-Sol was too complex to understand, and asking Astra to simplify it succeeded, with the proof also substantially revised.

With nearly identical prompts, the author rates Claude Opus 5.5's video output at 80 points and ChatGPT Astra 6 at no more than 8, and shares a comparison video.

A math preprint claims to prove a conjecture by Børve, Horiatakis, Kalck and others on the magnitude of module categories over algebras and its link to rank, with GPT-6 Astra listed among the collaborating models.
