// Perplexity does not provide a simple REST API to get models,
|
|
// so we have a table which we copy from their documentation
|
|
// https://docs.perplexity.ai/edit/model-cards that we can
|
|
// then parse and get all models from in a format that makes sense
|
|
// Why this does not exist is so bizarre, but whatever.
|
|
|
|
// 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 Perplexity added new models.
|
|
// Last Collected: Jan 23, 2025
|
|
|
|
// UPDATE: Jan 23, 2025
|
|
// The table is no longer available on the website, but Perplexity has deprecated the
|
|
// old models so now we can just update the chat_models.txt file with the new models
|
|
// manually and then run this script to get the new models.
