1. Model Output Encoding Issues

Currently, some models are prone to encoding issues when parameters are not set. In such cases, you can try setting the parameters such as temperature, top_k, top_p, and frequency_penalty. Modify the payload as follows, adjusting as needed for different languages: 
    payload = {
        "model": "Qwen/Qwen2.5-Math-72B-Instruct",
        "messages": [
            {
                "role": "user",
                "content": "1+1=?",
            }
        ],
        "max_tokens": 200,  # 按需添加
        "temperature": 0.7, # 按需添加
        "top_k": 50,        # 按需添加
        "top_p": 0.7,       # 按需添加
        "frequency_penalty": 0 # 按需添加
    }

​
2.Explanation of max_tokens

The max_tokens is equal to the context length. Since some model inference services are still being updated, please do not set max_tokens to the maximum value (context length) when making a request. It is recommended to reserve around 10k as space for input content.

​
3.Explanation of context_length

The context_length varies for different LLM models. You can search for the specific model on the Models to view the model details.

4. What Are the Differences Between Pro and Non-Pro Models

  1. For some models, the platform provides both a free version and a paid version. The free version is named as is, while the paid version is prefixed with “Pro/” to distinguish it. The free version has fixed Rate Limits, whereas the paid version has variable Rate Limits. For specific rules, please refer to: Rate Limits.
  2. For the DeepSeek R1 and DeepSeek V3 models, the platform distinguishes and names them based on the payment method. The Pro version only supports payment with recharged balance, while the non-Pro version supports payment with both granted balance and recharged balance.

5. Are There Any Time and Quality Requirements for Custom Voice Samples in the Voice Models

  • For cosyvoice2, the custom voice sample must be less than 30 seconds.
To ensure the quality of the generated voice, it is recommended that users upload a voice sample that is 8 to 10 seconds long, with clear pronunciation and no background noise or interference.

​
6. Output Truncation Issues in Model Inference

Here are several aspects to troubleshoot the issue:
  • When encountering output truncation through API requests:
    • Max Tokens Setting: Set the max_token to an appropriate value. If the output exceeds the max_token, it will be truncated. For the deepseek R1 series, the max_token can be set up to 16,384.
    • Stream Request Setting: In non-stream requests, long output content is prone to 504 timeout issues.
    • Client Timeout Setting: Increase the client timeout to prevent truncation before the output is fully completed.
  • When encountering output truncation through third-party client requests:
    • CherryStdio has a default max_tokens of 4,096. Users can enable the “Enable Message Length Limit” switch to set the max_token to an appropriate value.

​
7. Troubleshooting 429 Error During Model Usage

Here are some areas to check for the issue:
  • General Users: Verify your user tier and the corresponding Rate Limits (rate limits) for the model. If the request exceeds the Rate Limits, consider retrying after some time.
  • Dedicated Instance Users: Dedicated instances typically do not have Rate Limits. If a 429 error occurs, first confirm whether the correct model name for the dedicated instance is being called, and check if the api_key used matches the dedicated instance.

​
8. Account Balance Insufficient Despite Successful Recharge

Here are some areas to check for the issue:
  • Ensure the api_key being used matches the account that was just recharged.
  • If the api_key is correct, there may be a network delay during the recharge process. Consider waiting a few minutes and then retry.

​
9. Unable to Access Certain Models Despite Completing Real-name Verification

Here are some areas to check for the issue:
  • Confirm that the api_key being used matches the account that completed real-name verification.
  • If the api_key is correct, visit the Real-name Verification page to check the verification status. If the status shows “Verification in Progress,” you can try canceling and re-verifying.

​
10. Issues with fnlp/MOSS-TTSD-v0.5

  • The model tends to produce errors when the input text is too short
  • When using this model for dialogue synthesis, the input text format should be as follows:
    • [S1]Indicates Speaker 1 is speaking.[S2]Indicates Speaker 2 is speaking.
