Indeed. A few people [1] pointed on twitter that current best of Open Source Open Weight models are better than all the frontier model 6 - 8 months ago. And we heard Deepseek v5 and MiMO v3 are quite a leap.
I am not understanding the value proposition of these frontier model. Or at least not to a point they are looking at $1T or $2T market cap. Especially MiMO which may be ( correct me if I am wrong ) the most transparent model we currently have?
Or did I overlook or missing something? It is quite scary if true.
