API calls and assistants using o3-mini are failing

Assistant and open ai api calls using O3-mini are failing continuously for the last 1 hr. When running a query in assistant am seeing this error

Run failed

Sorry, something went wrong.

Anyone else facing this issue? Please let me know if there are any work arounds.

Same here, actually it is failing for the last 1 day

Whatever was changed, it caused us 10 hours of unnoticed downtime. The fix was switching to a different model.

I am having the same issue.
We tried switching to a different model, but when analyzing files, it’s causing hallucinations.
Any updates?

This is impacting us to. Hopefully @OpenAI_Support will post an update here soon

Also having this issue. o3 is the only model that works for our specific task.

We are experiencing the same issue. We use the o3-mini for a critical task, and during a client demo yesterday it malfunctioned, causing significant disruption. Please address this as soon as possible.

o3-mini via Assistants for the last day:

Same here in Threads, with all the o3mini variants.
