feels like maybe a stupid question but does your project support openrouter? or is the intended path to use openai for it like this explanation below? seems reasonable but i wanted to double check since i didn't see it mentioned anywhere and it seems to be getting popular lately

everything else in this message is claude output:

Yes! OpenRouter is fully OpenAI-compatible, so you should be able to use it with LLM.js by treating it as an OpenAI endpoint.

OpenRouter implements the OpenAI API specification for /completions and /chat/completions endpoints, allowing you to use any model with the same request/response format.

OpenRouter markets itself as "Fully OpenAI compatible" where "OpenAI SDK works out of the box".

So you should be able to do this with LLM.js:

import LLM from "@themaximalist/llm.js"

// Use OpenRouter as if it were OpenAI
const response = await LLM("hello", {
  service: "openai",  // Tell LLM.js to use OpenAI format
  apiKey: "sk-or-...",  // Your OpenRouter API key
  baseURL: "https://openrouter.ai/api/v1",  // Override the base URL
  model: "anthropic/claude-3.5-sonnet"  // Any OpenRouter model
})

The key is that when using OpenRouter, you just need to set the baseURL to "https://openrouter.ai/api/v1" and use your OpenRouter API key.

This means:

1. Your users with OpenRouter keys can use any of the 100+ models through OpenRouter
2. Your users with direct vendor keys can use those specific vendors
3. You don't need to build special OpenRouter support - just document how to configure it

Test this approach first to confirm it works with LLM.js, but based on OpenRouter's OpenAI compatibility, it should work seamlessly!
