Top 3 Open MoE Models Compared: Kimi, DeepSeek, GLM
Executive Summary / TL;DR Three trillion-scale open Mixture of Experts (MoE) models – Kimi K3 , DeepSeek V4 Pro , and GLM-5.2 – are reshaping the frontier of accessible AGI. We cut through the hype. We ran them on real GPUs, measured latency, and read the license fine print so you don’t have to. Kimi K3 leads in reasoning benchmarks, but its custom “open” license hides commercial landmines. DeepSeek V4 Pro is the serving-cost champion, fully Apache 2.0. GLM-5.2 surprises with multilingual coding and a permissive license that actually respects enterprise forks. Serving a 671B-parameter model on 4×H100 is feasible today – if you know the quantization tricks. We’ll show you the exact configs. The last time we benchmarked MoE models, we burned $3,700 in compute credits over a weekend, and one of our inference pods OOM’ed so hard it took the orchestrator down. That’s the price of real engineering analysis. Today, the stakes are higher. Three open-source behemoths have emerged, ...
