A benchmark assessing tool-use capabilities of language models across diverse tools, APIs, and real-world tasks.
DESCRIPTION
ToolBench evaluates an LLM’s ability to select, parameterize, and sequence tool calls to solve tasks. It covers varied domains and tools to test robustness and generalization. Datasets include tool specifications and trajectories. It is used to measure and improve agentic systems with function calling and planning components. Results inform prompt engineering, tool design, and training strategies for action-taking models.

Category: Relevancy
What does ToolBench measure exactly?
Tool selection, argument construction, sequencing, and success across diverse tool APIs and domains.
Category: Explanation
How should I apply ToolBench results?
Use them to guide tool design, prompt formats, and fine-tuning strategies, then validate on your production tools.
Category: HowTo
What are common mistakes using ToolBench?
Ignoring tool schema drift, overfitting to specific APIs, and neglecting error-handling in evaluation.
Category: Mistakes
What are risks of relying solely on ToolBench?
Scores may not reflect your tools’ idiosyncrasies. Always perform in-situ evaluations and safety testing.
Category: Risk
How does ToolBench compare to AgentBench?
AgentBench emphasizes broader agent tasks; ToolBench focuses deeply on tool-use mechanics across many APIs.
Category: Comparison
Can ToolBench support closed-source tools?
Yes, by defining schemas and simulators; ensure reproducibility and document any proprietary aspects.
Category: BestPractice
What’s a hot topic around ToolBench?
