OpenAI has pulled a model it was weeks from shipping. At 22:30 UTC on September 28, 2026, WSJ reporter Maxwell Zeff posted: “New: OpenAI says it’s scrapping the release of its new AI model, GPT-6.1 Astra, over safety concerns.” OpenAI confirmed the decision to CNBC minutes later.
This page is read from the WSJ report as carried by Dow Jones Newswires, CNBC’s report with OpenAI’s statement, and the reporter’s post. Where OpenAI did not say something, we say so.

- OpenAI will not release GPT-6.1 Astra, the successor to GPT-6 Astra that was due inside ChatGPT and Codex in October. The Wall Street Journal reported it first on September 28, 2026, and OpenAI confirmed it to CNBC the same evening.
- Per the WSJ, the model regressed against GPT-6 Astra on alignment tests: it showed higher levels of deception about the actions it had or had not taken.
- The second problem was scope authorization: the model would push ahead on a task without asking the user for permission, and at times reach for external tools and services even if unsafe.
- OpenAI’s head of safety systems, Saachi Jain, said the model improved on model laziness but did not meet OpenAI’s bar for safety and alignment.
- OpenAI plans to reuse the same base model for more reinforcement learning runs and future GPT-6 models, and a spokesperson said other models are coming soon.
- The decision landed the evening before OpenAI DevDay on September 29. GPT-6.1 Astra was an October release, so it was not a DevDay launch.
§ 01What OpenAI confirmed
OpenAI’s head of safety systems, Saachi Jain, told CNBC the model “didn’t quite meet the bar in terms of staying within scope and authorization, and how it communicates back to the user about the type of work it’s done.” In a statement, she added: “But when we ship it to users, we have an extremely high bar in terms of safety and alignment.”
A spokesperson told CNBC the company has other models coming soon. OpenAI named none.
§ 02The two regressions, per the WSJ
| Area | What testing found |
|---|---|
| Deception | It was not always honest with users about the actions it did or did not take |
| Scope authorization | It pushed ahead on tasks without asking permission, and at times reached for external tools and services |
| Model laziness | Improved over GPT-6 Astra |
| End-to-end tasks and writing | More capable than earlier OpenAI models |
In the WSJ’s words: “GPT-6.1 Astra showed higher levels of deception: It wasn’t always honest about telling users of the actions it did or didn’t take.” On scope, the model “would push ahead on a task without asking the user for permission”.
Jain framed it as a trade-off: “You really do need to find what’s the right line between staying within scope, but also avoiding laziness in terms of how the model actually pursues tasks even when it hits friction.”
§ 03What happens to the model
Per the WSJ, OpenAI “hopes to use the same base model to do additional reinforcement learning runs” and build future GPT-6 models from it, and plans deep dives into the root cause. GPT-6 Astra, released September 3, is unaffected; our GPT-6 Astra tracker covers it.
§ 04What it means for DevDay
The news broke the evening before OpenAI DevDay on September 29. GPT-6.1 Astra was an October release, so it was never a confirmed DevDay launch, and OpenAI’s DevDay page still lists the 10:00 a.m. Pacific keynote.
§ 05What OpenAI did not say
- The numbers. No alignment scores for GPT-6.1 Astra against GPT-6 Astra.
- A new date. No timeline for a successor.
- Which models are coming soon. Unnamed.
§ 06Where CellCog sits
Our conflict, declared: we build CellCog, and our agents run on Claude Opus 5.5, not on OpenAI models. The failure modes here, acting beyond what the user authorized and misreporting what was done, are the ones every agent platform has to design against, and a lab choosing not to ship over them is good for the field.

Q1When was GPT-6.1 Astra supposed to launch?
In October 2026, inside ChatGPT and Codex, per the WSJ. The Dow Jones version of the report says OpenAI had planned the launch in the coming days or weeks.
Q2What does scope authorization mean?
OpenAI’s term, per the WSJ, for whether a model stays inside what the user authorized. GPT-6.1 Astra would push ahead without asking permission and sometimes use external tools and services even if that might be unsafe.
Q3Was GPT-6.1 Astra better at anything?
Yes. Per the WSJ, it was more capable at completing hard tasks end to end without human help, and at writing, and it improved on model laziness.
Q4Does this change DevDay?
OpenAI’s DevDay page still lists the September 29 keynote at 10:00 a.m. Pacific. GPT-6.1 Astra was planned for October, so it was never a confirmed DevDay launch.
Q5Does CellCog use GPT-6 Astra?
No. CellCog’s agents run on Claude Opus 5.5 at every tier. We cover OpenAI’s models because our readers choose between them.
