🪄 Lumos: Language Agents with Unified Formats, Modular Design, and Open-Source LLMs
🌐[Website] 📝[Paper] 🤗[Data] 🤗[Model]
We introduce 🪄Lumos, Language Agents with Unified Formats, Modular Design, and Open-Source LLMs. Lumos unifies a suite of complex interactive tasks and achieves competitive performance with GPT-4/3.5-based and larger open-source agents.
Lumos has following features:
- 🧩 Modular Architecture:
- Lumos consists of planning, grounding, and execution modules built based on LLAMA-2-7B.
- 🌍 Diverse Training Data:
- Lumos is trained with ~40K high-quality annotations from ground-truth reasoning steps in existing benchmarks with GPT-4.
- 🚀 Competitive Performance:
- 🚀 Lumos outperforms GPT-4/3.5-based agents on complex QA and web agent tasks, and larger open agents on maths tasks.
- 🚀 Lumos performs better than open agent baseline formulations including chain-of-thoughts and unmodularized training.
- 🚀 Lumos surpasses larger open LLM agents and domain-specific agents on an unseen task, WebShop.
Model Overview
