Because I put non english model name: Minh Thành Nguyễn - zábavná čeština

When I put Teacher it starts to work.

Come on guys, it's not Y2K anymore with ASCII. UTF-8 is normal thing.

Dataset passed, problem was model title.

Also you have CORS issue there. At first the request did not come through. I had to install Chrome Extension to bypass CORS and after that I got some API response.

Hey @cyberluke, I tried to repro this on my end and noticed that the reason Minh Thành Nguyễn - zábavná čeština failed is because its length is >40 characters long, which is the limit for a tuned model name. If I cut down the length by removing a few characters, the tuning job succeeds.

I've filed an issue with the team to return more verbose error messages for this.

Hi @cyberluke

Thanks for reporting the issue, the root cause is what @vishal-dharm mentioned above, the tune model name exceeds the 40 characters limit, we will work on improving the messaging to help users quickly understand the problem!
