The code for the paper ROUTERBENCH: A Benchmark for Multi-LLM Routing System
- Create .env file in the root directory. With the following variables:
CONNECTION_STRING='your mongodb connection string'
if you want to use MongoDB as an embedding cache.
We use Martian as it provides a unified gateway to access all the models we use. Please visit withmartian.com to create a new account and get started.
- In root directory, run
pip install -e .to install the packages.
The pipeline relies on various command line arguments to specify the configuration. Alternatively, you can specify the
configuration in a yaml file and pass it to the command line. Example configurations are in the configs/ directory.
First, if desired, make sure there is a MongoDB instance running that you can connect to. If there is not one, ensure that local_cache: true to ensure that
the code only uses local files for caching.
Second, run convert_data.py --config=configs/convert_data.yaml to process the different data formats into a common format.
This script can take raw format from martian-evals repo, as well as other relevant input formats.
Third, run evaluate_routers.py --config=configs/evaluate_routers.yaml to use the processed data to evaluate different routers. It generates a csv file (long format) with the results of the evaluation, and creates an EvaluationCollection containing the results.
Fourth, run visualize_results.py --config=configs/visualize.yaml uses the EvaluationCollection to visualize the results in a performance-vs-cost plot.
For these configurations, the paths to the data files will need to be updated to use your local paths. Example files to recreate results from the paper are available on Hugging Face.
The code is designed to be easily extended. To add a new router, or convertor for a different input data format, simply look
at the abstract classes AbstractRouter and AbstractConvertor in routers/ and convertors/ respectively.
- For each PR, please run flake8, black, isort
flake8 $(git ls-files '*.py')
black $(git ls-files '*.py')
isort $(git ls-files '*.py')$(git ls-files '*.py') is for running only the files tracked by git, so exclude virtual env files or data files.
You may need to run pip install flake8 black isort if you don't have them installed.
