latest o1 models support developer messages rather than system messages

[lindaecho12]

It appears that the O1 model from o1-2024-12-17 no longer supports the system message role, but it does support the developer role. I am getting below errors when using systemmessage with o1 model:

azure.core.exceptions.HttpResponseError: (unsupported_value) Unsupported value: 'messages[0].role' does not support 'system' with this model.
Code: unsupported_value
Message: Unsupported value: 'messages[0].role' does not support 'system' with this model.

Will Autogen be updated to support the developer role for the O1 model?

@lindaecho12 according to Open AI specs system roles will be backward compatible with developer roles. For example, this will work:

import asyncio
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

async def main() -> None:
    agent = AssistantAgent("assistant", OpenAIChatCompletionClient(model="o1"), system_message="You are a helpful AI assistant.")
    print(await agent.run(task="Say 'Hello World!'"))

asyncio.run(main())

TaskResult(messages=[TextMessage(source='user', models_usage=None, content="Say 'Hello World!'", type='TextMessage'), TextMessage(source='assistant', models_usage=RequestUsage(prompt_tokens=23, completion_tokens=14), content='Hello World!', type='TextMessage')], stop_reason=None)

From the error you saw it looks like Azure API version is not up-to-date
