Composer 2.5 Fast is enabled in admin settings, but users (intermittently) can't use it [Cursor Enterprise]

Where does the bug appear (feature/product)?

Somewhere else…

Describe the Bug

Composer 2.5 Fast is enabled in admin settings, but users (intermittently) can’t use it. Cursor Enterprise account. Error shown is:

Model Blocked
This model has been blocked by your team admin admin settings.

Steps to Reproduce

Sometimes it gets better for a while if settings are toggled, but then (e.g. this morning) it starts happening again. I think it’s mostly (entirely?) happening with Fast mode. Happens across IDE, Glass, and cloud envs.

Expected Behavior

Admin enables a model and org’s users can actually use it.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi @Kevin_Scott!

Can you share a Request ID from a failing request?

@Colin This issue raised by @Kevin_Scott occurred for me on Request IDb6be18cb-1259-4f6f-b435-26f02c691c14.

I re-ran the failing message with toggled and it worked as expected. When I export the chat transcript, it does not show the failing request or the system message.

I’ll post the Request IDs in this thread when it happens again.

Stopped working in the middle of an agent convo.

Hey @Kevin_Scott and @smcguinness — thanks for the IDs, two different things going on here.

Kevin’s two requests both included a screenshot. Composer uses a small helper tool to work with images, and that helper picks from a short list (Gemini 3 Flash, Gemini 2.5 Flash, GPT‑5.4 mini, Claude Haiku 4.5, Grok 4). All five are disabled on your team’s allowlist, so the helper call fails and surfaces as a “Model Blocked” error even though Composer 2.5 Fast itself is allowed. That’s why it looks intermittent — only turns that actually contain an image hit this path. We’re tracking the UX on the engineering side and working to make that clearer; until then, I recommend either allowlisting any one of those models, switching to an image‑native model already on your allowlist (Claude Opus 4.7, GPT‑5.5, or Gemini 3.5 Flash) when you’re working with images, and flipping back to Composer 2.5 Fast afterward.

Seth’s request was a different failure that was caused by a disconnection in the http2 stream … could be a number of reasons (e.g. wifi dropping out momentarily etc). Glad that retrying that convo worked

Sounds plausible! Will be back in touch if we see this again after enabling the other models. Definitely agree on improving the UX here since there’s no way to know what was actually failing. Thanks!
