Achieving human-like planning and control with multimodal observations in an open world is a key milestone for more functional generalist agents. We introduce JARVIS-1, an open-world agent that can perceive multimodal input (visual observations and human instructions), generate sophisticated plans, and perform embodied control, all within the popular yet challenging open-world Minecraft universe. Specifically, we develop JARVIS-1 on top of pre-trained multimodal language models, which map visual observations and textual instructions to plans. The plans will be ultimately dispatched to the goal-conditioned controllers. We outfit JARVIS-1 with a multimodal memory, which facilitates planning using both pre-trained knowledge and its actual game survival experiences. JARVIS-1 is the existing most general agent in Minecraft, capable of completing over 200 different tasks using control and observation space similar to humans. These tasks range from short-horizon tasks, e.g., "chopping trees" to long-horizon tasks, e.g., "obtaining a diamond pickaxe". JARVIS-1 performs exceptionally well in short-horizon tasks, achieving nearly perfect performance. In the classic long-term task of ObtainDiamondPickaxe, JARVIS-1 surpasses the reliability of current state-of-the-art agents by 5 times and can successfully complete longer-horizon and more challenging tasks.

We list a series of videos showing JARVIS-1 playing Minecraft. You can find the videos on our Project Page.

This project is intended for running on Linux only. Support for other platforms is not provided.

We recommend using Anaconda to manage the environment. If you don't have Anaconda installed, you can download it from here.

conda create -n jarvis python=3.10
conda activate jarvis 

Make sure you have JDK 8 installed. If you don't have it installed, you can install it using the following command:

conda install openjdk=8

To check your JDK version, run the command java -version. You should see a message similar to the following (details may vary if you have installed a different JDK distribution):

openjdk version "1.8.0_392"
OpenJDK Runtime Environment (build 1.8.0_392-8u392-ga-1~20.04-b08)
OpenJDK 64-Bit Server VM (build 25.392-b08, mixed mode)

Once you have installed the required dependencies, you can run the prepare_mcp.py script to build MCP-Reborn. Make sure you have a stable internet connection before you begin.

python prepare_mcp.py

Then you can install JARVIS-1 as a Python package.

pip install -e .

JARVIS-1 relies on the weights of STEVE-I. You can download the weights from the script. Then you need to set the weights path in the file jarvis/steveI/path.py.

You need to set the environment variable TMPDIR and OPENAI_API_KEY first.

export TMPDIR=/tmp
export OPENAI_API_KEY="sk-******"

Then you can run the following command to start the JARVIS-1 agent.

python open_jarvis.py --task iron_pickaxe --timeout 10

Finally, you can see the JARVIS-1 agent playing Minecraft in the poped window. You can also run the following command to start the JARVIS-1 agent in the headless mode.

xfvb-run -a python open_jarvis.py --task iron_pickaxe --timeout 10

python offline_evaluation.py
or
xvfb-run -a python offline_evaluation.py

• Remove the self-check module for efficient planning.
• Current multimodal memory in assets/memory.json file is not complete. We remove the multimodal state and action sequence, which will be released in the future.
• The multimodal descriptor and the multimodel retrieval is not released yet. So you can only experience the language model part of JARVIS-1 now.

• Release multimodal descriptor to enable JARVIS-1 to understand the visual world. We plan to upload the multimodal memory on huggingface.
• Release learning.py to enables self-improving JARVIS-1 with growing memory.

JARVIS-1 is built upon several projects in Minecraft. Here are some related projects that you may be interested in:

• STEVE-1 is an instruction-tuned Video Pretraining (VPT) model for Minecraft. We use it as a part of controller in JARVIS-1.
• Minedojo is a simulator suite with 1000s of open-ended and language-prompted tasks built on the popular Minecraft game for embodied agent research.
• MC-TextWorld is a text world environment for Minecraft. It is designed to be a benchmark for text-based agents. We use it in the early version of JARVIS-1 to accumulate language memory.
