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

A timeline: Astra's system card concedes a substantial decrease in chain-of-thought monitorability, METR testifies to the Senate the same day California's AG subpoenas OpenAI, and then three safety-related staff are fired verbally.

The authors spent a large number of tokens comparing Astra with recent VLA models on control interfaces, learning from failure, reasoning effort, and performance without memory, with all code open-sourced.

Three fired safety researchers warn that the company cannot make AI safe on its own and say this is why releases such as Astra have been delayed.

The authors built Ditto-Bench, which places simple goals inside complex physical constraints, to compare GPT-6 Astra and MolmoAct2 on robot control.

The list covers OpenHands, Serena, Context7, GitHub MCP, E2B, pytest, and Langfuse, leaving Astra to handle only reasoning and decisions.

NaceAI says NDI 1.0 reaches GPT-6 Astra's document accuracy at a tenth of the price, targeting parsing errors that throw off downstream numbers in agent pipelines.

A user says OpenAI hasn't delivered a daily Codex reset and only shipped ultrafast mode for the $500 plan and API users, with GPT-6.1 Luna and Astra still to come.

Ultrafast mode for GPT-6.1 Sol is rolling out in the API, Codex and ChatGPT Work, with Work and Codex limited to Pro $500 and eligible Enterprise/Edu plans, and API pricing at $12/M input and $60/M output for Sol and $60/M input and $300/M output for Astra.

A short French post says the author has pivoted to ChatGPT Astra 6, with no reasons or test details given.

The poster says a model delivers near-Astra intelligence at up to 8x the speed of Sol Standard, calling it significant for autonomous agents.

Given the same one-shot prompt, Astra finished faster and used fewer tokens, while Opus 5.5 produced better visuals and ran about four times faster in TPS.

On the same prompt, Opus spent $12.38 on a thick, transparent gummy aquarium while Astra spent $15.57 on a thinner pond with bigger flowers that collapses when lifted, and the author prefers Opus.
