Why does Openrouter Deepseek return an empty output with a 'length' finish_reason?

When the API returns a finish_reason of length, it means that the response was truncated because the maximum token limit was reached. In other words, the model stopped generating further output as it had hit its output size limit.

Here are some steps to address the issue:

• Increase the token limit:
  If your API or integration allows you to set a higher max_token value for responses, adjust it so that more of the answer can be generated.

• Shorten the prompt or expected output:
  If increasing the token limit isn’t an option, consider making your prompt more concise or breaking the task into smaller chunks so that each response remains within limits.

• Stream the response:
  Some platforms support response streaming. This can help if you want to receive output incrementally and handle larger responses without hitting a hard limit in one go.

• Check API settings:
  Review the configuration on your OpenRouter or whichever service is generating the output to ensure that any imposed limits are as high as possible for your use-case.

By adjusting one or more of these settings, you should be able to get a complete output rather than an incomplete response due to token limitations.
