Unable to automatically summarize; the summarization feature cannot specify a model

Hey, this is a known issue. Summarization currently doesn’t use credentials from a custom API, it goes through Cursor’s internal infrastructure. If your subscription isn’t active, the request just fails.

Similar reports are already up:

The team is aware. There’s no ETA yet, but reporting it helps with prioritization.

Current workaround is to start a new chat before the context fills up, around 60 to 70% usage.

Let me know if you have any questions.
