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

A video jokes about Adobe's CEO watching someone rebuild Photoshop with GPT-6 Astra and publish it entirely for free, with no legal recourse since nothing illegal was technically done.

The post contrasts OpenAI's celestial names (Luna, Terra, Sol, Astra for moon, earth, sun and stars) and Anthropic's poetic names with Google's Gemini 4 Argon.

The author shows a web design generated by GPT-6 Astra, includes the prompt used, and says it has improved noticeably in this area.

A video puts Claude Sonnet 5.5, Claude Opus 5.5 and GPT-6 Astra side by side in a head-to-head comparison.

The tinygrad author complains that GPT-6 Astra adds three unit tests for a two-line change and recommends Kimi-K3 as more tasteful.

After the release of Gemini 4 Argon, a poll asks which model users would choose if they could only use one, with options including GPT-6 Astra and Claude Opus 5.5.

Astra analyzed a 1,300-symbol ciphertext from 1809, reconstructed the key and solved it with simulated annealing; a cryptographer has confirmed the historical cipher as solved.

Astra read the scanned ciphertext, reconstructed the missing key and used simulated annealing to recover a military briefing; Cryptiana marked the cipher as solved, though five symbols remain uncertain.

A Japanese user says dots is powered by Astra but is smarter and faster to respond than Astra in Codex, and suspects it runs on a Fast tier or a dedicated cloud PC.

A user reads DeepMind's post on preserving transparent architectures and speculates that Gemini 4 could be a looped architecture like GPT-6 Astra.

A visual account of one overnight agent workflow: five GPT-6 Astra agents each on a cloud computer with 36 apps connected, and anything they send waits for the user's approval.

The poster asks which $20 plan people would choose now that Gemini 4 beats GPT-6 Astra: Gemini, Claude or Codex.
