🤖 AgentVerse 🪐

A Framework for Multi-LLM Environment Simulation

【English | Chinese】

AgentVerse offers a versatile framework that streamlines the process of creating custom multi-agent environments for large language models (LLMs). Designed to facilitate swift development and customization with minimal effort, our framework empowers researchers to concentrate on their research, rather than being bogged down by implementation details.

✨ Features

🥳 Efficient Environment Building: Our framework provides a collection of essential building blocks for effortlessly creating a multi-agent environment. With only a few lines in a configuration file, you can easily construct basic environments such as a chat room for LLMs. This process entails defining the environment's settings and prompts for LLMs, enabling researchers like you to concentrate on experimentation and analysis.
⚙️ Customizable Components: AgentVerse simplifies the multi-agent environment by dividing it into five functional modules and defining their respective interfaces. For complex environments that cannot be constructed directly using the basic modules offered in AgentVerse, you can customize one or more of the interfaces within these five functional modules to efficiently create your own multi-agent environment according to your requirements.
🛠 Tools (Plugins) Utilization: AgentVerse supports the multi-agent environments with tools. Currently, AgentVerse supports tools provided in BMTools.

👾 Simple Demo Video

We demonstrate the following cases that are expertly crafted by AgentVerse.

NLP Classroom

In the NLP class, the professor and students engage in interactive communication. When students have a question, they raise their hands and patiently wait for the professor to call on them. Only after being called on by the professor, can students speak and ask their questions.

Use the following command to launch the NLP Classroom example:

python main_demo.py --task nlp_classroom_9players

classroom.mp4

Prisoner Dilemma

A prisoner's Dilemma is a thought experiment that challenges two completely rational agents to a dilemma: they can cooperate with their partner for mutual benefit or betray their partner ("defect") for individual reward.

Use the following command to launch the Prisoner Dilemma example:

python main_demo.py --task prisoner_dilemma

prison.mp4

Software Design

In the Software Design example, a code writer, a code tester and a code reviewer collaborate on the code generation problem. Given a problem, the code writer first composes the code implementation. The code tester runs the unit tests and provides the feedback. The code viewer then generates a review. After collecting the test feedback and review, the code writer iteratively refines the code.

Use the following command to launch the Software Design example:

python main_demo.py --task sde_team/sde_team_2players

sde.mp4

Database Administrator (DBA)

In the database diagnosis scenario, the Chief DBA monitors the system anomalies (e.g., slow queries, locks, crash down). If detected, the domain experts are alerted to analyze root causes, share insights, and suggest optimization solutions together. The Chief DBA then provides a summarized report to the user.

python main_demo.py --task db_diag

db_diag.mp4

Text Evaluation (ChatEval)

In the context of the text evaluation scenario, we recommend users explore the ChatEval repo. They've implemented a multi-agent referee team on AgentVerse to assess the quality of text generated by different models. When given two distinct pieces of text, roles within ChatEval can autonomously debate the nuances and disparities, drawing upon their assigned personas, and subsequently provide their judgments. Experiments indicate that their referee team, enriched with diverse roles specified in config.yaml, aligns more closely with human evaluations. This demo is built upon the Fastchat repo, and we'd like to express our appreciation for their foundational work.

Pokemon

In the game, agents can visit shops, train their Pokémon at the gym, and interact with one another. As a player, you take on the role of an agent and can engage with others at any time. There are 6 characters in the Pokémon environment who appeared in Pokemon Emerald: May, Professor Birch, Steven Stone, Maxie, Archie and Joseph.

To launch the Pokemon game, first launch a local server with the following command:

uvicorn pokemon_server:app --reload --port 10002

Then open another terminal in the project's root path and run the following command:

cd ui
# If you do not have npm installed, you need to install it before running the following commands 
# https://docs.npmjs.com/downloading-and-installing-node-js-and-npm
# We have tested on npm@9.6.4, node@20.0.0
npm install
npm run watch

Wait for the compilation to complete, and have fun! (WASD for moving around, and SPACE for launching a conversation.)

💡 Philosophy

Environment

At the core of our framework is the environment, which plays a crucial role in enabling researchers to study the behavior of agents under different conditions. We believe that the environment should be flexible and extensible, allowing researchers to easily customize it to fit their needs. To achieve this, we have abstracted the environment into five rule components, and implementing different environments is actually implementing different rules:

Describer: This component provides a description of the environment at each turn for each agent. You can customize the describer to define the specific requirements of their environment, such as the agents with whom an agent can interact.
Order: This component defines the order in which agents take actions within the environment. You can customize the order to reflect the desired interaction between agents. We provide several basic order options, including random, sequential, and concurrent (in which all agents take an action in each turn).
Selector: This component selects the valid messages generated by agents. Sometimes agents may generate invalid responses, and the selector is used to filter out unexpected results.
Updater: This component updates the memory of each agent. In certain cases, the response generated by one agent should not be seen by all agents (e.g., if agents are in different rooms). For each response, the updater updates only the agents who can see it.
Visibility: This component maintains the list of agents that each agent can see throughout the environment's changes. For example, when an agent moves from one room to another, the list of visible agents of each agent should be updated by visibility.

By abstracting the environment into these five components, we have created a highly flexible and extensible framework that enables researchers to easily build and customize their own multi-agent environments.

Agent

Another fundamental component is the agent. Currently we provide two types of agents: ConversationAgent and ToolAgent. You can also customize your own agent by inheriting BaseAgent class (tutorial coming soon).

✍️ Customize Your Own Environment

We have provided several examples in the agentverse/tasks directory. To customize your environment, you should

Create a task directory in agentverse/tasks
Write the configuration file
Write the output parser that parses the response of your agents.
Add your parser in agentverse/tasks/__init__.py

We will use a simple example in agentverse/tasks/nlp_classroom_3players to illustrate the procedure.

A Simple Example: Building a Classroom Environment

To illustrate how to customize your environment, we'll use a simple example of building a classroom environment where one agent is the professor, one is the student, and one is the teaching assistant.

1. Creating a Task Directory and Configuring the Environment

First, we need to create a task directory and write our configuration file for the environment. In the agentverse/tasks directory, create a new directory called nlp_classroom_3players. Inside this directory, create a config.yaml file and write the following configuration:

# config.yaml
environment:
  env_type: basic				# Use the basic environment provided in AgentVerse
  max_turns: 10					# Specify the maximum number of dialogue turns
  rule:
    order:
      type: sequential	# Use the sequential order
    visibility:
      type: all					# Each message can be seen by all agents
    selector:
      type: basic				# Basic selector (do not select)
    updater:
      type: basic				# Basic updater (update the message to all agents)
    describer:
      type: basic				# Basic describer (no description)

This configuration specifies that we will use the basic environment provided in AgentVerse, with a maximum of 10 dialogue turns. We'll use the sequential order, with all messages visible to all agents. We won't be using any selectors, our updater will update the messages to all the agents and our describer will provide no description.

2. Configuring the Agents

Next, we'll configure the agents. In the config.yaml file, we'll add the configuration for each agent. Here's an example configuration for the professor:

# config.yaml
agents:
  -
    agent_type: conversation
    name: Professor Micheal		# Name of the agent
    role_description: You are Prof. Micheal, ...	# Description of the agent
    memory: 
      memory_type: chat_history		# Will store all the chat history
    prompt_template: *professor_prompt
    llm:
      llm_type: text-davinci-003    # Will use OpenAICompletion LLM
      model: text-davinci-003       # The arguments passed to the api call
      temperature: 0.7
      max_tokens: 250

In this example, we'll use the conversation agent type. We've given the agent a name and a description, and we'll store the chat history in memory. We've also provided a prompt template with placeholders marked as ${placeholder}. These will be instantiated by the _fill_prompt_template method of the agent.

3. Writing an Output Parser

The next step is to write a simple parser for your agent's response. Because you may have specified the output format in your prompt template, you need to provide a corresponding parser. In this example, we inform the model to output in the following format in our prompt template

Action: Speak
Action Input: (the content)

We'll write a parser to extract the content from the agent's response. Refer to the code for more details. We've decorated our parser function with @output_parser_registry.register('classroom_parser') to register it with our framework. Finally, we import our parser in agentverse/tasks/__init__.py.

With these steps, we've successfully built a simple classroom environment and customized it for our needs.

Customization Guide for More Complex Environments

While we provide a basic framework for building environments with our five rule components, more complex environments may require further customization. A detailed documentation and tutorial is coming soon. Here we briefly introduce some steps you can take to customize your environment:

Customize the five rule components. Each rule component has an interface, allowing you to customize its behavior to suit your specific needs. It's important to note that these components are not necessarily independent and can interact through the rule_params dictionary in the environment. You can create your own rule components and integrate them with the existing ones to build more complex interactions between agents.
Customize the environment itself. Our basic environment provides a default execution order for the five rule components that is suitable for most cases, but you can inherit the BaseEnvironment class and write your own run method to implement a more sophisticated execution order.
Customize the agent. Depending on your specific use case, you may also need to inherit the BaseAgent class. For example, you may want to use your local LLM as your agents or create agents with specialized knowledge or skills.

🔎 Examples

Currently, we offer some simple examples in the agentverse/tasks directory, each demonstrating different possibilities of our framework. While the performance of these examples may not be optimal due to limited prompt engineering, they are intended to showcase the capabilities of our framework, such as allowing the use of tools.

Here's a brief overview of each example:

nlp_classroom_3players: This example illustrates a simple case in which agents will speak in sequential order.
nlp_classroom_9players: This is an NLP class example. Here, students can raise their hand when they have a question, and the professor can call on the students to let them ask. Students are only allowed to speak after they are called on.
nlp_classroom_9players_group: This example showcases group discussions. The professor may initiate a group discussion when needed, and students can exclusively interact with fellow students within the same group during the discussion.
nlp_classroom_3players_withtool: Students in this classroom can use Bing search API when listening to the class.
math_problem_2players_tools: A simple example demonstrating how two agents can use the WolframAlpha API to play an arithmetic game.
prisoner_dilema: The Prisoner's Dilemma is a thought experiment involving two rational agents facing a choice between cooperating for mutual benefit or betraying their partner for individual gain.
db_diag: The Chief DBA monitors (agents) the database system for anomalies and alerts memory and CPU agents if any are detected. They (agents) analyze root causes and suggest optimization solutions. The Chief DBA (agent) provides a diagnosis summary to the user, who can give instructions or evaluate the proposed solutions' effectiveness.
sde_team: In the SDE team, code writer, code tester and code reviewer collaborate on the code generation problem.
pokemon: This example intimates Pokemon game.
