@user691, thanks for the details, that’s a helpful signal. Version 3.6.12 is on the Nightly track, so the fix is already there. For Stable, I’m waiting for confirmation from others in the thread so we can make sure it works for all setups.
For everyone else, as soon as you can update or try Nightly, please reply and confirm whether requests for gpt-5.5 reach the backend with a normal BYOK setup, without the gpt-55-xhigh hack. That will let us close the thread.
A couple quick notes from your post:
- Slow gpt-5.5 vs Composer 2.5 is about model or proxy latency, not this bug. If you want us to look into it, please open a separate thread with a couple Request IDs from slow requests. Chat > top right menu > Copy Request ID.
- Composer 2.5 not working with this BYOK setup is also separate, with a different root cause. Best to open a separate thread with the exact error, your version, and steps to reproduce, so it doesn’t get mixed up with the GPT-5.5 fix here.
