But while we’re “guessing”: Xiaomi MiMO
My money is on Moonshot and this being Kimi K3.5. The measured tps and latency is in-line with K3's tps and latency from Moonshot.
MiniMax M3.5 is also possible (but the MiniiMax provider is a lot more performant than the lab behind ox-alpha, so less likely).
The only question now is if it's 5.3v, 5.4/5.5 or a dedicated flash/vision model
Ox Alpha
Given the traction the model has received, it is extremely newsworthy to know who's developing and hosting it.
