🔧 LLM-Tool-Integrated-Reasoning-TIR-Papers
A curated collection of papers on Tool-Integrated Reasoning (TIR) — a rapidly evolving research direction where Large Language Models (LLMs) interact with external tools such as calculators, search engines, code interpreters, and web APIs to enhance reasoning, decision-making, and factual accuracy.
🧠 "The ability to use tools is what sets humans apart from other animals."
🤖 Likewise, the ability to use tools is what transforms an LLM into an agent.
TIR marks a critical milestone in the evolution of LLMs: it extends models beyond static parametric knowledge, enabling them to dynamically interact with the external world via:
- 🖥️ Python interpreters
- 🔍 Search engines
- 🧮 Calculators
- 🌐 Web APIs
Although this list focuses on Tool-Integrated Reasoning, we also include earlier or adjacent works on LLMs + Tools that may not explicitly involve reasoning, in order to provide a more complete historical and technical context.
📌 Note: This list focuses on tool-integrated reasoning with text-only LLMs and does not include multimodal models.
