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

The same prompt had Astra and Opus 5.5 each build a playable browser version of Happy Wheels, with Astra closer to the original and Opus using more exaggerated effects, plus a ranking at the end of the video.

A user notes that after Opus 5.5's release it dominates all discussion, with Astra and Sol no longer mentioned, and feels OpenAI needs to deliver something big next.

The view argues that if Anthropic's mid-tier Sonnet matches the flagship, OpenAI's low-price-for-performance advantage shrinks, and it would need GPT-6.1 Astra to respond quickly.

Under the same camera and lighting, the two models each build Tokyo Tower in 3D, compared from exterior to observation deck interior, and the author finds Opus 5.5 better.

He argues it is not contradictory that good programmers report poor results with GPT-6 Astra, since the skill set good programming requires has changed between past and present.

The author ported a video-making skill built for Opus 5.5 to GPT-6 Astra and found Astra lagged in output quality, time and token use, questioning why anyone would keep using Codex.

A Turkish developer published the full code of Mola, a cafe management game made with GPT-6 Astra without coding knowledge, including a 3D scene, 450+ automated tests and an Android project.

A user says Astra Pro now gives nearly useless answers, ignores prompt instructions and finishes in 5-6 minutes tasks that once took 40+ minutes, suspecting OpenAI is cutting corners on compute.

A prediction post lists what OpenAI might ship at its Sept 29 Dev Day: Astra minor, an ultra-fast mode, an agent called "o", a new Pro Max plan and possibly its first hardware device.

An article speculates that Astra may use a Looped Transformer that runs the same layers multiple times, so 22 layers of weights run twice give the equivalent of 44 layers of compute, and discusses hidden reasoning.

The author says Muse produced a real animation in two minutes with natural Chinese speech and stable text, while Astra took three hours, used 6% of a 20x quota, and only made the image move.

A Japanese post rounds up Dev Day rumors: GPT-6.1/6.5 Astra, an AEON service competing with Grok, an Ultra-Fast mode, a merge of Chat and Work, and OpenAI's first hardware device.
