GLM 5.3 and all previous models don't have a vision encoder and can only accept text. Ox-Alpha can accept video and images, so unless Z-ai added a pretty good vision encoder for this model, I don't think so. 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…
I hope this is not Kimi K3.5 because it really sucks. It is very slow, not particularly smart when it comes to coding, and easily starts going in circles - when not straight up going into a doom loop.
