HUSKY: A Unified, Open-Supply Language Agent for Complicated Multi-Step Reasoning Throughout Domains

Current developments in LLMs have paved the best way for creating language brokers able to dealing with advanced, multi-step duties utilizing exterior instruments for exact execution. Whereas proprietary fashions or task-specific designs dominate present language brokers, these options typically incur excessive prices and latency points because of API reliance. Open-source LLMs focus narrowly on multi-hop query answering or contain intricate coaching and inference processes. Regardless of LLMs’ computational and factual limitations, language brokers provide a promising method by methodically leveraging exterior instruments to deal with sophisticated challenges.

Researchers from the College of Washington, Meta AI, and the Allen Institute for AI launched HUSKY, a flexible, open-source language agent designed to deal with various, advanced duties, together with numerical, tabular, and knowledge-based reasoning. HUSKY operates by two key phases: producing the following motion to take and executing it utilizing knowledgeable fashions. The agent makes use of a unified motion house and integrates instruments like code, math, search, and commonsense reasoning. Regardless of utilizing smaller 7B fashions, intensive testing reveals that HUSKY outperforms bigger, cutting-edge fashions on numerous benchmarks. It demonstrates a strong, scalable method to fixing multi-step reasoning duties effectively.

Language brokers have turn into essential for fixing advanced duties by leveraging language fashions to create high-level plans or assign instruments for particular steps. They usually depend on both closed-source or open-source fashions. Earlier brokers used proprietary fashions for planning and execution, which, whereas efficient, are pricey and inefficient because of API reliance. Current developments give attention to open-source fashions, distilled from bigger trainer fashions, providing extra management and effectivity however typically specializing in slim domains. In contrast to these, HUSKY employs a broad, unified method with an easy knowledge curation course of, using instruments for coding, mathematical, search, and commonsense reasoning to deal with various duties effectively.

HUSKY is a language agent designed to unravel advanced, multi-step reasoning duties by a two-stage course of: predicting and executing actions. It makes use of an motion generator to find out the following step and related instrument, adopted by knowledgeable fashions to execute these actions. The knowledgeable fashions deal with duties like producing code, performing mathematical reasoning, and crafting search queries. HUSKY iterates this course of till a closing resolution is reached. Skilled on artificial knowledge, HUSKY combines flexibility and effectivity throughout various domains. It’s evaluated on datasets requiring diversified instruments, together with HUSKYQA, a brand new dataset designed to check numerical reasoning and data retrieval skills.

HUSKY is evaluated on various duties involving numerical, tabular, and knowledge-based reasoning, plus mixed-tool duties. Utilizing datasets like GSM-8K, MATH, and FinQA for coaching, HUSKY reveals robust zero-shot efficiency on unseen duties, constantly outperforming different brokers comparable to REACT, CHAMELEON, and proprietary fashions like GPT-4. The mannequin integrates instruments and modules tailor-made for particular reasoning duties, leveraging fine-tuned fashions like LLAMA and DeepSeekMath. This permits exact, step-by-step problem-solving throughout domains, highlighting HUSKY’s superior capabilities in multi-tool utilization and iterative activity decomposition.

In conclusion, HUSKY is an open-source language agent designed to deal with advanced, multi-step reasoning duties throughout numerous domains, together with numerical, tabular, and knowledge-based reasoning. It makes use of a unified method with an motion generator that predicts steps and selects applicable instruments, fine-tuned from robust base fashions. Experiments present HUSKY performs robustly throughout duties, benefiting from domain-specific and cross-domain coaching. Variants with completely different specialised fashions for code and math reasoning spotlight the influence of mannequin selection on efficiency. HUSKY’s versatile and scalable structure is poised to deal with more and more various reasoning challenges, offering a blueprint for creating superior language brokers.
