GPT-5.2
GPT-5.2 stopped being testable on Aug 19, 2026. OpenAI’s backend now refuses this model on subscription accounts, so our lab cannot run it anymore.

This pin is retired
- We did not remove it. The vendor did. When we ask for this model, the app now refuses the request.
- Its page stays up so old links keep working, but no new rounds will ever land here.
- Older rounds are not deleted. They sit in Logs with the test-kit version they ran under.

Still running in the same app
These pins take the same prompts in the same app, every round.

How to read this
Boards only show rows from the current test kit, v6. This pin has no rows in that kit and never will, so it no longer appears on any board. Its older rounds stay in Logs, labeled with the kit they ran under.
