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:
- Summarizing conversations does not inherit model settings
- Auto Summarization problem with custom OpenAI proxy
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.
