Synthesize and Reward -- Reinforcement Learning for Multi-Step Tool Use in Live Environments

Ibrahim Abdelaziz, Asim Munawar, Kinjal Basu +4

Training LLMs to orchestrate multi-step tool calls is held back by three coupled obstacles: realistic stateful execution environments are costly to build, synthetic training querie…

Simulating Complex Multi-Turn Tool Calling Interactions in Stateless Execution Environments

Maxwell Crouse, Ibrahim Abdelaziz, Kshitij Fadnis +6

Synthetic data has proven itself to be a valuable resource for tuning smaller, cost-effective language models to handle the complexities of multi-turn tool calling conversations. W…

Reducing the Scope of Language Models

David Yunis, Siyu Huo, Chulaka Gunasekara +1

Large language models (LLMs) are deployed in a wide variety of user-facing applications. Typically, these deployments have some specific purpose, like answering questions grounded…

Activated LoRA: Fine-tuned LLMs for Intrinsics

Kristjan Greenewald, Luis Lastras, Thomas Parnell +6

Low-Rank Adaptation (LoRA) has emerged as a highly efficient framework for finetuning the weights of large foundation models, and has become the go-to method for data-driven custom…

A Library of LLM Intrinsics for Retrieval-Augmented Generation

Marina Danilevsky, Kristjan Greenewald, Chulaka Gunasekara +13

In the developer community for large language models (LLMs), there is not yet a clean pattern analogous to a software library, to support very large scale collaboration. Even for t…

MTRAG: A Multi-Turn Conversational Benchmark for Evaluating Retrieval-Augmented Generation Systems

Yannis Katsis, Sara Rosenthal, Kshitij Fadnis +7

Retrieval-augmented generation (RAG) has recently become a very popular task for Large Language Models (LLMs). Evaluating them on multi-turn RAG conversations, where the system is…
