AISummary
GPT-6 Astra Ultrafast, running on NVIDIA Blackwell GPUs, is now available in the OpenAI API and to eligible ChatGPT Work and Codex users.
The source says Ultrafast offers up to 8x faster token generation than Astra Standard mode, which can shorten coding agents' response times between tool calls.
OpenAI also says it uses its own models to keep optimizing inference software on NVIDIA GPUs after deployment.
AIWhy it matters
The source ties a specific speed claim to coding agents' edit-test-debug loops, showing where faster token generation changes developer workflows.
