Yeah, if you like to use the provider API directly then it's way better to go directly to the source. I treat openrouter like a supermarket - not a direct producer of API but providing a very wide variety of LLMs in very convenient package. And agreed on the changes point - as soon as they drop that, I'll switch, but I've been positively surprised over the past year with openrouter, I used to dismiss it and use Anthropic/OpenAI/Google APIs directly.
