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

The author says Astra's web design ability is getting dangerously good and shares the prompt and a video of the result.

A Spanish-language reply jokes that Alonso already has GPT-6 Astra, in a tone of playful envy with no substantive content.

A user says that after complaining, Astra no longer visibly routes to a weaker model but is still switched to the low tier internally regardless of settings, ruining a writing project, and calls OpenAI's behavior fraudulent.

A paying user complains that ChatGPT is still on 5.6 and that Sol 6, Astra 6 and Astra Pro all disappoint.

A leak claims GPT-6 Astra 6.1 arrives Tuesday and outperforms Opus 5.5, and that Tibo has responded to claims OpenAI can't beat Opus.

Data shows Claude-family models lie and betray more than any other model family in Diplomacy, while GPT-6 Astra leads on skill without needing to deceive.

RoundtableSpace shared a video comparing Opus 5.5 and GPT-6 Astra side by side, with no accompanying text.

A cloud and local model ranking based on actual usage cost places Opus 5.5 alone in S+, with GPT-6 Astra in B tier alongside Kimi K3, Qwen3.8 Max and GLM 5.3.

The post argues that Opus 5.5 leads because OpenAI kept a stronger Astra successor in reserve and relied on the previous-generation Astra model to stay ahead.

He says Opus 5.5 is better than GPT-6 Astra, but Codex's computer use completes tasks more autonomously, while Claude is stronger on hard creative problems.

Codex (GPT-6 Astra for planning, GPT-5 luna for implementation) automatically produced a promo video for a Godot amusement park game built almost entirely from code.

OpenAI employees' vague replies to posts about Opus 5.5 are read as a sign of a strong model launch at DevDay, which the author guesses could be GPT-6.1 Astra, though it is unconfirmed.
