25 Automatic Multi-Step Reasoning and Tool Use

Multi-step reasoning and tool use in LLMs involve the model’s ability to break down complex tasks into manageable steps and leverage external resources or APIs to accomplish these tasks. This capability significantly extends the problem-solving potential of LLMs, allowing them to tackle more complex, real-world scenarios. Its key characteristics include the following:

Task decomposition: This refers to the model’s ability to take a complex input or goal and divide it into smaller, more manageable sub-tasks that can be solved sequentially or hierarchically. Instead of trying to solve an entire problem in one step, the model creates a structured plan or sequence of reasoning steps that progressively ...
