Describe the Bug
Summary
Cursor-hosted DeepSeek V4.1 Flash (deepseek-v41-flash-1017, model picker only, BYOK: false) has failed on every request since this morning. The UI shows:
We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.
Agent Host logs showconnectCode: ResourceExhausted,willRetry: false, andusedTokens: 0(rejected before inference starts).
The same failure happens on Cursor Desktop and Cursor Web (same account, same model). Other models (e.g. Grok, Composer) work in the same sessions.
This does not look like a local cache, MCP, or network issue on my machine.
Environment
- Client: Cursor 3.27.14, macOS arm64 (Apple M4)
- Model:
deepseek-v41-flash-1017(included/hosted route, not my DeepSeek API key) - BYOK: false (composer log:

Yesterday (2026-10-29) the same model worked on the same conversation (e.g. successful turns around 22:37–23:07 JST). Failures with ResourceExhausted also appeared intermittently last night, but this morning the route has been 100% failing since ~09:23 JST. |

| There was no Cursor app update between the last success (09:21) and the first failure (09:23). |
Log details (Agent Host)
Typical failure line:
connectCode: ResourceExhaustedwillRetry: falseusedTokens: 0modelId: deepseek-v41-flash-1017transportMode: websocket(sometimeshttp1_sse)
Example diagnostics block:
[AGENT_ERROR_DIAGNOSTICS] requestId=2c1ae74e-a931-4669-b4f3-af4218946753 ... connectCode: ResourceExhausted
Dashboard Other Models usage is ~2% (not monthly pool exhaustion).
Cursor Web
I reproduced the same Provider Error when using deepseek-v41-flash-1017 on Cursor Web (not only Desktop). That rules out local Mac cache, local Agent host-only quirks, and “fix by clearing ~/.cursor” for this issue.
What I already tried (no improvement)
- MCP disabled
- Network → Run Diagnostics (pass)
- Disable HTTP/2 / HTTP compatibility
- New chats, re-select model
- Other models work on Desktop and Web
Ask
Please check the hosted routing / capacity for deepseek-v41-flash-1017 for this account. Per your docs, this model is served via inference partners, not DeepSeek’s own API — so DeepSeek’s public status may not reflect this outage.
Priority Request IDs for lookup:
45ba2ec8-1fac-4cde-9e81-578d10950ba7, 2c1ae74e-a931-4669-b4f3-af4218946753, 615054c7-6527-4f49-bf24-be219a785fc6 (last success)
Thanks.
Steps to Reproduce
- Sign in to Cursor (Desktop or Web) with a plan that includes hosted models.
- Open a new chat (Agent or Ask).
- Select model: DeepSeek V4.1 Flash (
deepseek-v41-flash-1017) from the model picker. Do not use BYOK / custom DeepSeek API key. - Send any short message (e.g. “hello”).
- Within ~1–2 seconds, the chat fails with: “We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.”
- Copy Request ID from the chat “…” menu — logs show connectCode ResourceExhausted, usedTokens 0, willRetry false.
- Repeat on Cursor Web with the same account and model — same error (not Desktop-only).
- Switch to another hosted model (e.g. Composer or Grok) in the same session — request succeeds.
