Thanks, BTW, now I have learned about OpenRouter.
It doesn't look like they have a way to filter down to "open" models. By this of course I mean "downloadable, local models".
I suppose if you know the "family" (Gemma, Qwen, etc.), I can just go to those models and test…
I've simply been pulling down what is popular from the LM Studio front end (and what runs on my hardware) and testing in situ.
