input_length_error
Prompt is too long: the number of tokens exceeds the maximum allowed limit.
This error has been identified and solved.
Reason
The HTTP 400 Bad Request error in the Anthropic API, specifically the message "prompt is too long: 103078 tokens > 102398 maximum," indicates that the request exceeds the maximum allowed token limit for the API.
Here are the key reasons for this error:
Token Limit Exceeded: The prompt contains more tokens than the maximum allowed by the Anthropic API. Each API has a specified limit on the number of tokens that can be processed in a single request, and exceeding this limit results in a 400 error.
Invalid Request Format: This error falls under the
invalid_request_error
category, which means there is an issue with the format or content of the request, in this case, the length of the prompt.
Solution
To fix the "prompt is too long" error in the Anthropic API, you need to ensure that your prompts do not exceed the maximum token limit. Here are some concise solutions:
Trim the Prompt
Reduce the length of your prompt to fit within the allowed token limit.
Optimize Prompt Length
Use clear, concise language in your prompts.
Provide specific instructions to guide the model's responses.
Leverage system messages to set context and behavior expectations.
Dynamic Trimming
Implement a mechanism to dynamically trim the prompt if it exceeds the token limit before sending the request to the API.
Retry with Adjusted Prompt
If the prompt is too long, trim it and retry the request. This can be automated to handle cases where the initial prompt exceeds the limit.
