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.
-
π₯³ 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.
-
βοΈ 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.
-
π Tools (Plugins) Utilization: AgentVerse supports the multi-agent environments with tools. Currently, AgentVerse supports tools provided in BMTools.

We demonstrate the following cases that are expertly crafted by AgentVerse.
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, students can 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
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
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
In the database diagnosis scenario, the Chief DBA monitors the database system for anomalies. If detected, the memory and CPU agents are alerted to analyze root causes and suggest optimization solutions. The Chief DBA then provides a summarized diagnosis to the user, who can also contribute by giving instructions or evaluating the effectiveness of proposed solutions.
You should first configure the database tool in BMTools, and launch the BMTools server according to the guidance. Then use the following command to launch the Database Administrator example:
python main_demo.py --task db_diag
db_diag.mp4
In the game, agents can visit shops, train their PokΓ©mon 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 PokΓ©mon 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
npm install
npm run watch
Wait for the compilation to complete, and have fun!

You can create a multi-agent environments provided by us. Using the classroom scenario as an example. In this scenario, there are nine agents, one playing the role of a professor and the other eight as students.
python3 main.py --task nlp_classroom_9players
We also provide a local website demo for this environment. You can launch it with
python3 main_demo.py --task nlp_classroom_9players
After successfully launching the local server, you can visit http://127.0.0.1:7860/ to view the classroom 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
, andconcurrent
(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.
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).
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.
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.
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.
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.
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.
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 theBaseEnvironment
class and write your ownrun
method to implement a more sophisticated execution order. - Customize the agent. Depending on your specific use case, you may also need to inherite the
BaseAgent
class. For example, you may want to use your local LLM as your agents or create agents with specialized knowledge or skills.
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.
