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

The robot explores a room to remember where items are stored and fetches medicine on request, achieved by removing the intermediate action layer so GPT calls five existing skills directly.

A robotics-room roundup argues GPT-6 Astra's strong instruction following lifts everything beneath it, System 1 may be optional, diffusion has no future, and humanoid control is 80% solved.

An analysis says OpenAI's new Ultrafast tier runs on Nvidia GPUs rather than Cerebras, weakening the case that fast inference requires wafer-scale chips, and asks which hardware will power Astra.

A developer shares a short parent-and-child scene on Specs glasses, with visuals and interaction generated using OpenAI Astra and Lens Studio.

A Japanese user used GPT-6 Astra to fill in missing documentation and improve demodulation logic, successfully receiving terrestrial digital and BS broadcasts on a cheap SDR board.

Someone measured GPT-6 Astra Ultrafast at 300 tok/s and guesses it is not running on Cerebras, but possibly on low-batch GB300 or other chips.

A user had Astra configure Bluetooth and Wi-Fi on NixOS and even rewrite drivers to get the touchscreen working on an old Surface Pro 4.

A Japanese developer had Astra design a control board for the STEVAL-VL53L9 with an ESP32-P4 CPU on eight layers, and it worked on the first try, while a comparison model failed twice.

A Japanese account claims Tuesday's DevDay may bring the Astra series, an AEON product, an Ultra-Fast mode and OpenAI's first hardware, all unconfirmed.

A post says Astra handles task and scene understanding plus motion planning in robot demos, while KPI converts those high-level intentions into real-time force and contact control, and asks whether foundation models will absorb today's specialized Physical AI stack.

The author ran zero-shot robot control with Astra, Opus 5.5, Grok 4.7 and MolmoAct2 on the same task, without sped-up or cherry-picked demos, and concludes low-level control remains the bottleneck.

A joking request to get GPT-6 Astra 6.1 Ultra Ultrafast running on Cerebras hardware as soon as possible.
