name: toolalpaca-eval
description: Evaluates a language model's ability to generalize tool-use capabilities to unseen tools and APIs through multi-turn interaction, parameter selection, and final response generation. It measures how well compact models trained on simulated data can adapt to real-world and out-of-dataset tool scenarios without task-specific fine-tuning. Use when the user wants to benchmark on ToolAlpaca Evaluation Set, GPT4Tools Test Set, or asks about evaluating this task. Reports Overall.

## What this evaluates

Evaluates a language model's ability to generalize tool-use capabilities to unseen tools and APIs through multi-turn interaction, parameter selection, and final response generation. It measures how well compact models trained on simulated data can adapt to real-world and out-of-dataset tool scenarios without task-specific fine-tuning.

## Datasets

- **ToolAlpaca Evaluation Set** — total ?; splits: test (-1); repo https://github.com/tangqiaoyu/ToolAlpaca
- **GPT4Tools Test Set** — total 602; splits: test (602); repo https://github.com/tangqiaoyu/ToolAlpaca

## Metrics

- `Procedure` — range: percent
  - Evaluates the model's proficiency in accurately selecting suitable actions, utilizing correct parameters, and avoiding redundant actions. Scored as a percentage.
- `Response` — range: percent
  - Measures whether the final response can satisfy the user's instruction. Scored as a percentage.
- `Overall` **(primary)** — range: percent
  - Evaluates the whole process, requiring the correctness of both procedure and response. Scored as a percentage.
- `SR` — range: percent
  - Successful rate of the entire instance (thought, action, and arguments combined). Scored as a percentage.

## Input / output format

**Input**: User instruction/query along with relevant tool documentation/API specifications.

**Output**: A structured sequence of tool calls (actions with parameters) followed by a final natural language response.

## Scoring recipe

```python
def evaluate(model_output, tool_docs, gold_answer):
    prompt = f'Tool docs: {tool_docs}\nGold answer: {gold_answer}\nModel output: {model_output}\nEvaluate Procedure, Response, Overall.'
    gpt4_response = call_gpt4(prompt)
    return parse_gpt4_scores(gpt4_response)
```

## Common pitfalls

- Evaluation relies heavily on GPT-4 as an automated judge, which may introduce bias or inconsistency compared to human annotators.
- The simulated evaluation subset uses synthetically generated tools, so performance may not fully transfer to real-world API constraints or error handling.
- Success rate (SR) metrics on the GPT4Tools test set explicitly exclude non-tool-use cases, which could artificially inflate generalization scores.

## Evidence (verbatim from paper)

> To evaluate the models, we utilize GPT-4 for machine evaluation across all experiments, with an additional manual evaluation conducted specifically for the simulated subset. We prompt GPT-4 with the tool documentation and the standard answer from the human annotator and expect it to evaluate the performance in the following aspects:

* •

    Procedure: This metric evaluates the model’s proficiency in accurately selecting suitable actions, utilizing correct parameters, and avoiding redundant actions.

* •

    Response: This criterion measures whether the final response can satisfy the user’s instruction.

* •

    Overall: This metric evaluates the whole process, requiring the correctness of procedure and response.
