Abstract

We introduce Voyager, the first LLM-powered embodied lifelong learning agent in Minecraft that continuously explores the world, acquires diverse skills, and makes novel discoveries without human intervention. Voyager consists of three key components: 1) an automatic curriculum that maximizes exploration, 2) an ever-growing skill library of executable code for storing and retrieving complex behaviors, and 3) a new iterative prompting mechanism that incorporates environment feedback, execution errors, and self-verification for program improvement. Voyager interacts with GPT-4 via blackbox queries, which bypasses the need for model parameter fine-tuning. The skills developed by Voyager are temporally extended, interpretable, and compositional, which compounds the agent's abilities rapidly and alleviates catastrophic forgetting. Empirically, Voyager shows strong in-context lifelong learning capability and exhibits exceptional proficiency in playing Minecraft. It obtains 3.3x more unique items, travels 2.3x longer distances, and unlocks key tech tree milestones up to 15.3x faster than prior SOTA. Voyager is able to utilize the learned skill library in a new Minecraft world to solve novel tasks from scratch, while other techniques struggle to generalize.

Voyager discovers new Minecraft items and skills continually by self-driven exploration, significantly outperforming the baselines.

Introduction

Building generally capable embodied agents that continuously explore, plan, and develop new skills in open-ended worlds is a grand challenge for the AI community. Classical approaches employ reinforcement learning (RL) and imitation learning that operate on primitive actions, which could be challenging for systematic exploration, interpretability, and generalization. Recent advances in large language model (LLM) based agents harness the world knowledge encapsulated in pre-trained LLMs to generate consistent action plans or executable policies. They are applied to embodied tasks like games and robotics, as well as NLP tasks without embodiment. However, these agents are not lifelong learners that can progressively acquire, update, accumulate, and transfer knowledge over extended time spans.

Let us consider Minecraft as an example. Unlike most other games studied in AI, Minecraft does not impose a predefined end goal or a fixed storyline but rather provides a unique playground with endless possibilities. An effective lifelong learning agent should have similar capabilities as human players: (1) propose suitable tasks based on its current skill level and world state, e.g., learn to harvest sand and cactus before iron if it finds itself in a desert rather than a forest; (2) refine skills based on environment feedback and commit mastered skills to memory for future reuse in similar situations (e.g. fighting zombies is similar to fighting spiders); (3) continually explore the world and seek out new tasks in a self-driven manner.

Mortal Kombat 4 Apk Download For Android Better

Since MK4 was originally designed for Arcade, PlayStation, and Nintendo 64, there isn't an "official" standalone app on the Google Play Store. To play it, you generally have two options: 1. The Emulation Route (Recommended)

remains a landmark title for being the series' first leap into 3D graphics

: If you want to play Mortal Kombat Gold (the enhanced version of MK4), you can use Redream .

Fortunately, because MK4 is an older title, it does not require a high-end flagship phone. Most budget and mid-range devices can handle it effortlessly. Minimum Requirement Recommended Android 5.0 (Lollipop) Android 10.0 or higher Processor Quad-Core 1.5 GHz Octa-Core 2.0 GHz+ RAM 4 GB or more Storage 500 MB free space 1 GB free space Step-by-Step Installation Guide

Instead, you should download two things from :

One major hurdle is that MK4 was designed for six buttons (five plus a block/run button). Here is the optimal touch layout:

If you experience lag, try closing background apps to free up RAM. Since this is a 3D game, older devices may struggle slightly, but on modern hardware, it should run perfectly.

When searching for a "Mortal Kombat 4 APK," it is crucial to understand how emulation works to protect your device from malware.

The transition to 3D polygons gave the series' signature finishing moves a stark, visceral aesthetic. Understanding the "Mortal Kombat 4 APK" Landscape

If you chose DuckStation or ePSXe, the emulator requires a PlayStation system BIOS file (such as scph1001.bin ) to run games natively. Download a PS1 BIOS file legally online.

Conclusion

In this work, we introduce Voyager, the first LLM-powered embodied lifelong learning agent, which leverages GPT-4 to explore the world continuously, develop increasingly sophisticated skills, and make new discoveries consistently without human intervention. Voyager exhibits superior performance in discovering novel items, unlocking the Minecraft tech tree, traversing diverse terrains, and applying its learned skill library to unseen tasks in a newly instantiated world. Voyager serves as a starting point to develop powerful generalist agents without tuning the model parameters.
