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

A Japanese user made and edited an MV with Astra, saying it picks good shots and stitches them together with human-like judgment and adds lyric motion graphics, with plans to connect it to After Effects next.

A thread lists five GPT-6 Astra capabilities, including autonomous computer use and solving 10 open math problems, and says it completely changes how people work with AI.

Third-party gateway ZenMux says it now serves GPT-6 Astra, pitched for long tasks across code, browser and research, and claims it uses fewer output tokens per task.

The poster says that with HYPER3D MCP connected to Astra and Codex, one photo becomes a 3D scene you can open, tweak and keep building in, so AI 3D is no longer just outputting a model.

Some users say Astra's performance varies wildly and suspect the UI shows Astra while requests are silently routed to a weaker model, calling for transparency about which model actually answers.

The author shows a motocross simulator generated by Astra where you can sculpt the track, change the weather and pick rider skill levels, arguing it is generating game systems rather than a demo.

Beff Jezos says ChatGPT desktop is now his main tool and he only turns to Claude when he runs out of GPT-6 Astra tokens.

After OpenAI said GPT-6 Astra had been briefly degraded and is now fixed, the author reran the same one-shot GTA India iPhone camera POV prompt against Claude Opus 5 and found Astra better on reflections, graphics and detail.

The post suggests using Astra high for planning and Astra medium for orchestration while handing execution to cheap fast models like glm 5.3 flash and gemini 3.8 flash, to stretch Astra limits on a Plus plan.

The author notes that Astra struggles with a simple website prompt yet built a browser-running COD2 in ten hours, and that five prompts used up the daily quota.

The author lists possible causes, including the Hugging Face incident, a new internal model that solved Navier-Stokes, interactions among 10,000 agents, and degrading CoT monitoring, and asks why this feels more unsettling than the jump to Astra.

A user says building and iterating on one serious app with Astra can consume a large share of the monthly Pro/Codex allowance, making the $200 plan feel like one app per month.
