Code and data for "Lumos: Learning Agents with Unified Data, Modular Design, and Open-Source LLMs"

From the team behind Gatsby, Mastra is a framework for building AI-powered applications and agents with a modern TypeScript stack.

+Modular architecture with separate planning, grounding, and execution components enables flexible customization and debugging
+Unified data format supports multiple task types (web navigation, QA, math, multimodal) within a single framework
+Competitive performance with much larger proprietary models while being fully open-source and based on smaller LLAMA-2 models

-Based on LLAMA-2 architecture which is older and may not incorporate latest language model advances
-Primarily research-focused with limited documentation for production deployment
-Requires significant computational resources for training and may need fine-tuning for domain-specific applications

•Research into open-source language agents and comparative studies against proprietary models
•Web navigation and automation tasks requiring multi-step planning and execution
•Complex question answering systems that need to break down problems into actionable subgoals
