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

The author prompted GPT-6 Astra to write a Palestrina-style motet in LilyPond and shared two resulting Renaissance motets on video.

Google's table has Gemini 4 Argon winning 14 of 19 tests and tying 53-53 on an independent index, while Astra answers correctly more often (63% vs 50%), for a net 42 vs 43.

A user warns not to prompt GPT-6 Astra into producing things you need in reality, calling the output vibe-coded and opaque.

The author asked GPT-6 Astra (Ultra) to rank four blockchains purely on technical merit and shared the resulting screenshot.

A study reports GPT-6 Astra answered 49 of 50 hard theoretical physics problems correctly and even found errors in experts' reference answers.

An AI engineer says ChatGPT Astra spent six hours cracking a 217-year-old encrypted Napoleon-era letter using administrative records, period French literary patterns and libraries.

A developer says GPT-6 Astra only slightly improved UI while greatly boosting computer use, and that GPT-6 Sol and 6.1 Sol code worse than GLM 5.3 and Kimi K3, also complaining about quota cuts.

The post argues OpenAI is sidelined after safety issues shelved 6.1 Astra, and suggests Anthropic release Fable 5.5 this week on Pro plans with lower pricing and better token efficiency to take share.

A Japanese user had GPT-6 Astra edit their juggling footage into an exaggerated, meme-style cut and shared the result.

A creator's workflow uses Seedance2.5 for video while GPT-6 Astra and GPT-image2.5 handle preprocessing and image generation, teasing an upcoming piece.

Reddy says token spend is moving from Anthropic to OpenAI: Luna leads small closed models, Sol 6.1 suits non-coders, and Astra is great for coding if affordable but less dense than Fable.

A joke that OpenAI supporters are pushing Anthropic to ship Fable 5.5 just so they can claim GPT-6.1 Astra beats it on release.
