Hi,  
I am using crewai version 0.65.2 and wanted to test the o1 model.  
Using the Azure AI Studio I deployed an o1 model called:  
o1-preview-standard  
And also deployed a gpt-4o model called:  
gpt-4o-standard

Here is a complete example:

```python
from __future__ import annotations

# .env variables setting:
# AZURE_API_BASE=https://<my_endpoint>.openai.azure.com/
# AZURE_API_KEY=<my_key>

from crewai import Agent, Crew, Task
from crewai_tools import CodeInterpreterTool

code_interpreter_tool = CodeInterpreterTool()

def main():
    agent = Agent(
        role="Best Mathematician Agent",
        goal="Calculate the Fibonacci number.",
        backstory="""
        You are an expert mathematician.
        You are trying to calculate the Fibonacci number.
        """,
        tools=[code_interpreter_tool],
        verbose=True,
        llm="azure/o1-preview-standard",
    )

    task = Task(
        name="Calculate Fibonacci Number",
        description="""
        Calculate the Fibonacci number for n={n} by generating Python code for it and running it with your tools.
        """,
        expected_output="The Fibonacci number integer value.",
        agent=agent,
    )

    crew = Crew(
        tasks=[task],
        agents=[agent],
        verbose=True,
    )

    crew_result = crew.kickoff(
        inputs={
            "n": "15",
        }
    )

    print(crew_result.raw)

if __name__ == " __main__":
    main()

```

When running it I received the following error:

```plaintext

And the console prints:

```

Things I’ve tried:

1. Upgrading to crewai version 0.79.4, same error occurred.

2. Changing the llm on my agent from: “azure/o1-preview-standard” to “azure/gpt-4o-standard”. This worked perfectly, I received answer 610.

This seems to be a problem with how crewai configures litellm, is it a bug or am I doing something wrong?

@zorx Please edit the question and add the code.

The OpenAI `o1` model doesn’t support the `system` message. If you didn’t add it and got this error, then it’s a bug in the CrewAI SDK. Otherwise, remove it.

Wrong:

```
from litellm import completion 

response = litellm.completion(
    model="o1-mini",
    messages=[
        { "role": "system", "content": "You're a helpful assistant." },
        { "role": "user", "content": "Hey, how's it going?" },
    ],
)

print(response)

```

Correct:

```
from litellm import completion 

response = litellm.completion(
    model="o1-mini",
    messages=[
        { "role": "user", "content": "Hey, how's it going?" },
    ],
)

print(response)

```

Sorry, I added a complete example that reproduces the error with the full error output.  
Note that I have deployed my models using Azure AI Studio so to fully reproduce the example you must deploy in Azure as well.

I am not using completion and messages, I am using Crew, Agent, and Task.

This is totally expected.

Have you tried using the CrewAI [`LLM`](https://docs.crewai.com/concepts/llms#llm-configuration-options) class? Does the error still persist?

Setting

> llm=“o1-mini”

in the Agent and

> #.env OPENAI\_API\_KEY=\<my\_key\>

works without the error, returning 610.

But I want to use the Azure AI Studio deployment, not openai directly.

I meant using the `LLM` class as follows:

```
from crewai import LLM

my_llm = LLM(
    ...
)

agent = Agent(
    llm=my_llm,
    ...
)

```

As far as I know, you can use Azure AI Studio because the CrewAI `LLM` class leverages LiteLLM in the background. See the LiteLLM [docs on how to use Azure AI Studio](https://docs.litellm.ai/docs/providers/azure_ai).

Maybe @tonykipkemboi can elaborate on that issue?

Thanks, I tried setting the following in my Agent llm:

```python
from crewai import LLM

my_llm=LLM(model="azure/o1-preview-standard")

agent = Agent(
    llm=my_llm,
    ...
)

```

But the same error I posted on initially occurred.

We are trying to do the same and getting the same error. Looks like crewai in the backstage configure the completition call adding the role in a wrong for o1 models api.  
will this problem solved in the future ?  
Can you officially state that Azure o1-mini and o1-preview are supported ?
