Describe the Bug
I’m trying to use openrouter with my business plan cursor. Here’s what I tried:
- In cursor settings, I enabled OpenAI Key, Override OpenAI Base URL
- I added a model anthropic/claude-sonnet-4
- Verify succeeded
So I moved on to actually using it. With setting the anthropic/claude-sonnet-4, I sent a request and keep receiving the following error. It complains about claude-sonnet-4-20250514 model, but it’s not what I set nor added in cursor setting’s models:
Request ID: 237d0b9d-2c8d-4c60-93c3-79713c202da9
{“error”:“ERROR_OPENAI”,“details”:{“title”:“Unable to reach the model provider”,“detail”:“We encountered an issue when using your API key: Provider was unable to process your request\n\nAPI Error:\n\n\nRequest failed with status code 400: {\"error\":{\"message\":\"claude-sonnet-4-20250514 is not a valid model ID\",\"code\":400},\"user_id\":\"org_2xieMh0oafnhrsCDR0hXQVboNIQ\"}\n”,“additionalInfo”:{}},“isExpected”:true}
