Python: New Feature: Add Support for "developer" Role for OpenAI o1 model

[ymuichiro]

Currently, the OpenAI O1 model introduces a new role "developer". However, passing the conventional "system" role results in an error. To address this issue, the following changes are proposed.

Proposal

1. Add a Method to the ChatHistory Class

   • Implement a method to handle role conversion or substitution logic for compatibility with the O1 model.

2. Expand the AuthorRole Enum

   • Add "developer" as a new value to the AuthorRole enum.

3. Improve Developer Experience (UX)

   • If the "system" role is mistakenly passed, the logic should internally convert it to "developer" for better UX.
   • However, since all models other than O1 still use "system", simply adding support for the "developer" role seems to be the most optimal solution at this point.

Background

• The O1 model no longer supports the "system" role, causing errors when it is passed.
• The introduction of the "developer" role must be integrated in a way that preserves compatibility with other models.

Platform

• Language: Python
