馃獎 Agent Lumos: Unified and Modular Training for Open-Source Language Agents
馃寪[Website] 馃摑[Paper] 馃[Data] 馃[Model] 馃[Demo]
We introduce 馃獎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:
- 馃З Modular Architecture:
- 馃З Lumos consists of planning, grounding, and execution modules built based on LLAMA-2-7B/13B and off-the-shelf APIs.
- 馃 Lumos utilizes a unified data format that encompasses multiple task types, thereby enabling the developed agent framework to conveniently support a range of interactive tasks.
- 馃實 Diverse Training Data:
- 馃實 Lumos is trained with ~56K diverse high-quality subgoal/action annotations from ground-truth reasoning steps in existing benchmarks with GPT-4.
- 鈿掞笍 Lumos data can be instrumental for future research in developing open-source agents for complex interactive tasks.
- 馃殌 Competitive Performance:
- 馃殌 Lumos is comparable or even beats GPT-series agents on web/complex QA tasks Mind2Web and HotpotQA, and larger open agents on math and multimodal tasks.
- 馃殌 Lumos exceeds contemporaneous agents that have been fine-tuned with in-domain HotpotQA, Mind2Web and ScienceQA annotations, such as FiReAct, AgentLM, and AutoAct.
- 馃殌 Lumos performs better than open agent baseline formulations including chain-of-thoughts and integrated training.
- 馃殌 Lumos surpasses larger open LLM agents and domain-specific agents on unseen tasks, WebShop and InterCode_SQL.
Model Overview
