Yes, not great, not terrible. I gave it my personal test (a coding task), it produced semi-decent quality code that produced a minor error, after pasting the error it failed to solve it during multiple rounds. I believe another 2-3 years and we'll have quite usable small models.

No, where can I try it? I saw a huggingface link but I wonder if they host it themselves somewhere to like how Alibaba does with Qwen chat.

There is a HuggingFace space (probably not official) at: https://huggingface.co/spaces/orangewong/xiaomi-mimo-7b-rl You might have to wait a minute to get a response. Also, the space doesn't seem to have turn-taking implemented, so after giving the Assistant's response, it kept on generating the Human's next message and so on and so forth.
