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

A developer shares a WinUI interface demo generated in one shot by GPT-6 Astra, highlighting that it added a draggable scrubber for rewinding.

The author shares a full recording of Astra controlling MolmoAct2 YAMs to complete a task in real time, seeing potential but judging it far from practical for real-world robotics deployment.

The author was still skeptical of AI video editing when Astra launched, but says Opus 5.5 is a different beast and that teaching Claude Code their style could 10x their output.

A short prediction post claims Sonnet 5.5 will outperform GPT-6 Astra, offering no evidence beyond 'you'll see'.

The author posts a video showing GPT-6 Astra handling NX CAM tasks, captioned 'ruh roh', hinting at a surprising result.

A video quotes Altman saying that with Astra you no longer need to write prompts, and that he runs a few hundred agents every night, managing a digital workforce from his phone.

A Japanese user compared the two models on game development: Opus 5.5 better captured the reference characters' traits and adjusted smoothly to follow-up instructions, while Astra was weaker at adjustments, making Opus the stronger choice overall.

The post says Opus 5.5 performs at the level of Claude Fable 5.1, beats GPT-6 Astra on most benchmarks, and costs 40% less to run than Opus 5.

3D artist Stefan used AI to build a game character in a day and a half, with root-based movement, energy drain, a leaf shield and VFX, and shared a step-by-step workflow of confirming each piece before moving on.

The author shares a video of a web design generated by GPT-6 Astra, calling its web design ability "dangerously good," and includes the prompt.

On Artificial Analysis's new 70-task Terminal-Bench-Science 0.1 benchmark of real research tasks, GPT-6 Astra beats Claude in research scenarios, with Qwen3.8-Max the best Chinese model.

The poster wonders whether OpenAI will reveal more of what its internal model bel, reportedly significantly more capable than the released GPT-6 Astra, has done during DevDay.
