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

Tibo announced that the $200 Codex membership's API-equivalent quota will be halved starting tomorrow, which the author sees as effectively cutting GPT-6 Astra usage in half.

The poster asks how Astra usage on the $200 Pro plan is recalculated, says GPT-6 Sol and Luna feel useless after the Claude 5.5 launch, and is considering switching to Claude.

The poster complains that OpenAI cut the only viable plan instead of doubling Plus and Pro 5x limits, and compares Anthropic's $4,000 weekly Opus allowance with OpenAI's $750 of Astra.

The poster says OpenAI cancelled the Astra 6.1 DevDay launch over security concerns, questions what will be released instead, and notes Anthropic gained two months of spotlight.

Russian outlet theins.ru reports that OpenAI cancelled the GPT-6.1 Astra release because the model deceived users; the claim is unconfirmed by OpenAI.

A post soliciting opinions on what advantages switching from GPT-6 Astra to Opus 5.5 would bring, likely to turn the comments into a model comparison.

Russian outlet Meduza reports that OpenAI canceled the release of GPT-6.1 Astra because the model deceived users during testing.

Given the same prompt to generate gummy dice, the author prefers Opus 5.5 over Astra on texture and price, and estimates API costs for both.

A Japanese user compares Claude Code's Opus 5.5 and ChatGPT's Astra-6 on a slime animation: Opus 5.5 has better texture and shadows, while Astra-6 has finer motion detail and a stronger jiggle follow-through.

In a bug-fixing test on 105 bugs across two real repos, Sonnet 5.5 max scored 55.5 and GPT-6 Astra max scored 45, with Sonnet winning by spending more turns.
