Gemni 3 Flash stops to respond

Support Bug Reports

From last evening, my Gemni 3 flash stops to respond that it always throw Provider Error after ‘Planning next moves’, I’ve confirmed it is not a context issue since I also create new chat to test. It is quite annoying since Gemni 3 Flash is my main model for months, and it really bothers me.

I’ve tried other models, Gemni 3 Pro and sonnet 4.5 are both working without error, only Gemni 3 Flash is responding with the provider error.

See below for my screenshots and error request id for a gemni 3 flash request

Request ID: 23f55162-9287-49b7-a3c3-5c5e6e6fbe92

Hey, thanks for the report. I see the request ID and screenshots - helpful.

A couple quick checks:

  1. Network diagnostics: Cursor Settings > Network > Run Diagnostics - share the results
  2. Which mode: try the same request in regular chat (Ask mode) - does the error repeat?
  3. Custom API keys: Settings > Models - do you have any custom API keys enabled (OpenAI Base URL or Gemini API key)?
  4. MCP servers: if you’re using MCP servers - try disabling them temporarily

Other models work - so it’s not a general network issue.

Let me know the results, especially network diagnostics and regular chat. If it continues - I’ll pass it to the team with your request ID.

I think I find the issue, with needle mcp( Needle MCP Server — Local AI for Needle | Needle Engine Documentation ) on, gemni 3 pro flash doesn’t work in agent mode.
In chat mode it works and by turning needle mcp off, it works in agent mode.

Although not 100% assure this mcp is the cause, why other model works with it and why the error thrown is provider error
