1. Try obtaining the HTTP error code to initially locate the issue

a. In your code, try to print the error code and error message (message). Using this information, most issues can be located.

HTTP/1.1 400 Bad Request
Date: Thu, 19 Dec 2024 08:39:19 GMT
Content-Type: application/json; charset=utf-8
Content-Length: 87
Connection: keep-alive

{"code":20012,"message":"Model does not exist. Please check it carefully.","data":null}

• Common error codes and their causes:
  • 400: Incorrect parameters. Refer to the error message (message) to correct invalid request parameters.
  • 401: API Key is not properly set.
  • 403: Insufficient permissions. The most common reason is that the model requires real-name authentication. For other cases, refer to the error message (message).
  • 429: Rate limits triggered. Refer to the error message (message) to determine whether the issue is related to RPM / RPD / TPM / TPD / IPM / IPD. You can consult Rate Limits to understand the specific rate-limiting policies.
  • 504 / 503:
    • Generally caused by high system load. You can try again later.
    • For chat and text-to-speech requests, you can try using streaming output ("stream": true). Refer to Streaming Output for more details.
  • 500: An unknown server error occurred. You can send an email to help@siliconflow.com for troubleshooting.

b. If the client does not output corresponding information, you can try running the curl command in the command line (taking an LLM model as an example):

curl --request POST \
   --url https://api.ap.siliconflow.com/v1/chat/completions \
   --header 'accept: application/json' \
   --header 'authorization: Bearer Replace_with_your_apikey' \
   --header 'content-type: application/json' \
   --data '
{
  "model": "Remember_to_replace_with_model",
  "messages": [
    {
      "role": "user",
      "content": "Hello"
    }
  ],
  "max_tokens": 128
}' -i

2. Try switching to another model to see if the issue persists

3. If you are using a proxy, consider disabling the proxy and trying again
