The pull request review addresses several aspects of the proposed changes. It highlights a potential bug concerning the token limit of the newly added "o3-mini" model, recommending verification of this value to prevent adverse effects on client operations. Although no obvious security vulnerabilities are noted, the review advises careful examination of access rules and validations related to the new model to avoid potential security issues. The coding practices are commended, particularly the use of try-except blocks to handle KeyError exceptions, which maintains backward compatibility and handles situations where a model-specific tokenizer might be unavailable. Additionally, the review suggests implementing logging within the exception block to facilitate debugging and monitor the use of fallback tokenizers, ensuring better oversight when new models lack explicit tokenizers.

  1. Potential Bugs:
  • The newly added model "o3-mini" has the same token limit as other models. Ensure this value is correct as it might affect client operations.

2. Security Vulnerabilities:

   • There's no indication in this diff of exploitable security vulnerabilities, but adding a new model without updating corresponding access rules or validations elsewhere could potentially introduce security concerns if not handled properly in other parts of the system.

3. Adherence to Coding Standards:

   • Using try-except block is appropriate for handling the KeyError, which ensures backward compatibility and graceful degradation when a model-specific tokenizer is missing. This practice aligns well with standard error handling codes.
   • Consider adding logging in the exception block to monitor when the fallback tokenizer is used. This can help in debugging and monitoring the behavior when new models do not have an explicitly defined tokenizer.

Set the default model to gpt-4o not gpt-4.
