    It doesn’t seem to be. Their Chinese website talks about buying AI credits, their English website only has a waitlist but this looks more like a new closed commercial product than anything else.

    Also, check the appendix in the paper, I think it’s a bit concerning that the second author is responsible for the writebench benchmark they use to make their claims about the model. That is, the evaluation isn’t independent from the authors.

    I mean, I’m not saying they’re not right, just that this is a yellow flag to investigate more.

    Second flag is I don’t see a journal this will/is published in. Arxiv is not peer reviewed.
