From top of my head:

https://nousresearch.com/ They do much more than Hermes

https://pluralis.ai/ has distributed models the network owns

And many others filling very different niches.

I would also count DeepSeek because they publish and share so much. Their new caching prices are very good for not that bad models. Last week I needed to generate content via API and I spent literally $3.40 where before I would've paid easily $200. But you have to connect directly as it seems OpenRouter messes up caching somehow.
