FollowBench: A Multi-level Fine-grained Constraints Following Benchmark for Large Language Models (ACL 2024)

We introduce FollowBench, a Multi-level Fine-grained Constraints Following Benchmark for systemically and precisely evaluate the instruction-following capability of LLMs.

• FollowBench comprehensively includes five different types (i.e., Content, Situation, Style, Format, and Example) of fine-grained constraints.
• To enable a precise constraint following estimation on diverse difficulties, we introduce a Multi-level mechanism that incrementally adds a single constraint to the initial instruction at each increased level.
• To evaluate whether LLMs' outputs have satisfied every individual constraint, we propose to prompt strong LLMs with constraint-evolution paths to handle challenging open-ended instructions.
• By evaluating 13 closed-source and open-source popular LLMs on FollowBench, we highlight the weaknesses of LLMs in instruction following and point towards potential avenues for future work.

Metrics

• Hard Satisfaction Rate (HSR): the average rate at which all constraints of individual instructions are fully satisfied
• Soft Satisfaction Rate (SSR): the average satisfaction rate of individual constraints across all instructions
• Consistent Satisfaction Levels (CSL): how many consecutive levels a model can satisfy, beginning from level 1

⚙️ How to Evaluate on FollowBench

Install Dependencies

conda create -n followbench python=3.10
conda activate followbench
conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.7 -c pytorch -c nvidia
pip install -r requirements.txt

Model Inference

cd FollowBench/
python code/model_inference.py --model_path <model_name_or_path>

LLM-based Evaluation

cd FollowBench/
python code/llm_eval.py --model_path <model_name_or_path> --api_key <your_own_gpt4_api_key>

Merge Evaluation and Save Results

Next, we conduct rule-based evaluation and merge the rule-based evaluation results and LLM-based evaluation results using the following script:

cd FollowBench/
python code/eval.py --model_paths <a_list_of_evaluated_models>

The final results will be saved in the folder named evaluation_result.
