// OpenRouter has lots of models we can use so we use this script
// to cache all the models. We can see the list of all the models
// here: https://openrouter.ai/docs#models

// To run, cd into this directory and run `node parse.mjs`
// copy outputs into the export in ../models.js

// Update the date below if you run this again because OpenRouter added new models.
// Last Collected: Feb 23, 2024
