Confirmed from OpenAI’s customer story dated Sept. 14, 2026. Live openai.com returned 403 this pass. This is a customer/engineering write-up, not a new frontier model launch. Anthropic’s newsroom, fetched live, still led with its Sept. 10 threat report and the Sept. 1 Claude Fable 5.1 / Mythos 5.1 announcement. Live x.ai/news returned 403; a Sept. 9 archive listed nothing newer than Sept. 4. Live Meta AI blog returned 400. Google DeepMind’s public index still listed September WeatherNext and Gemini 3.8 Flash items.
- ConfirmedOpenAI published a customer story dated Sept. 14. The post says Perplexity uses GPT-6 Astra to write communications, change software, and monitor production systems, and that staff check in less often than with earlier models. Johnny Ho, Perplexity’s cofounder and chief strategy officer, is quoted saying the model can craft communications, edit real-world systems, and monitor production software in ways earlier generations could not. The piece describes asking Astra to build small testing programs that stand in for other services so workflows can be checked end to end.
- UnverifiedIndependent measurement of how often Perplexity staff intervene, and of production reliability under Astra, is not available beyond the OpenAI post and quoted remarks. Live openai.com returned 403.

OpenAI put up a customer story dated Sept. 14.
The post says Perplexity uses GPT-6 Astra to write communications, change software, and monitor production systems. It says staff check in less often than they did with earlier models.
Johnny Ho, Perplexity’s cofounder and chief strategy officer, is quoted: “We can have the model craft communications, edit real-world systems, and monitor our production software in a way that previous generations were not able to.”
The piece describes asking Astra to build small testing programs that stand in for other services — for example a language-model interface or a connector — so a workflow can be checked from start to finish.
Ho is also quoted: “We’re actually able to trust it with full end-to-end systems and check in on it much less frequently than previous generations of models.”
This is a customer write-up. It is not a new frontier model launch.
