Porting AutoGen 0.2 agentchat.contrib.agent_builder functionality to autogen v0.4

[aayushmittal2]

Question about AgentBuilder functionality in AutoGen v0.4

I'm looking for guidance on the AgentBuilder functionality in AutoGen v0.4. In the previous version (v0.2), there was a feature available at agentchat.contrib.agent_builder that allowed dynamic agent creation and configuration. However, I can't seem to find its equivalent in the v0.4 documentation.

This is the functionality I am reffering to v0.2 documentation

Specific questions:

1. Is there an equivalent functionality in v0.4?
2. If not, what's the recommended approach for dynamic agent creation in v0.4?

Any help or guidance would be greatly appreciated!

It is not currently ported.

However, @davidxwwang is working on a port. Perhaps we can have a discussion here.

Hi @ekzhu, @davidxwwang

Just wanted an update if agentchat.contrib.agent_builder AgentBuilder functionality in available in AutoGen v0.4
If not any ETA on it will be really helpful.

Thanks!

If you can start with a simple sketch of the solution can help a lot. E.g., a python script showing a draft implementation.

@ekzhu @aayushmittal2, l start a Discussion thread which l prepare to add Autobuild to main branch #5573, Sorry for starting this work so late, as I have been on vacation recently due to the Chinese New Year.

Sure, thanks for the quick response @ekzhu!

Below is a high-level snippet from our current v0.2 setup using AgentBuilder.
I’d love any pointers on how to replicate or migrate this to AutoGen v0.4:

from autogen.agentchat.contrib.agent_builder import AgentBuilder

builder = AgentBuilder(
    config_file_or_env="OAI_CONFIG_LIST",          
    builder_model=[AZURE_OPEN_AI_MODEL_4o],     
    agent_model=[AZURE_OPEN_AI_MODEL]              
)

def build_agents(building_task: str):
    agent_list, agent_configs = builder.build(building_task, llm_config, coding=False)
    return agent_list, agent_configs

async def get_building_agents(build_bot_model, bot_details):
    """
    Demo function showing how we call our builder and use the returned agent configs.
    """
    agent_list, agent_configs = build_agents(
        f"""
        Team definition: {build_bot_model.description}
        + always include one agent named "Final_Agent" that provides the final results.
        ... (additional instructions, system messages, etc.) ...
        """
    )...


async def build_bot(build_bot_model: BuildBotRequestModel):
    overall_agents_ids, overall_agents = await get_building_agents(build_bot_model, bot_details)
    return {"agents": overall_agents}

I think if you want to go from textual specs to instances of agents, you can use component specification of agents. E.g., you can go from a YAML definition of a group chat to an instance of a group chat. This is already possible in v0.4 AgentChat and AutoGen Studio.

The implementation of auto build isn't too complex: https://github.com/microsoft/autogen/blob/0.2/autogen/agentchat/contrib/agent_builder.py, and most of the code structure is general. So I imagine porting it shouldn't be too hard.
