Hey, this isn’t an outage. Composer 1.5 generally works, but you might see latency spikes, especially on requests with a large context. The “Taking longer than expected” message is a client-side timeout when the model takes too long to send the first token.

The team is aware of this issue. A few things that might help:

1. Try resyncing the codebase index: Cmd+Shift+J > Indexing & Docs, then restart Cursor. This helped a few users with the exact same symptoms.

2. If it happens again, send the Request ID (chat context menu in the top right > Copy Request ID). This lets us check what was happening on the backend.

Switching to auto as a workaround is a good temporary option.
