GLM-5.2 is a 753-billion-parameter MoE model (MIT) with a 1M context. The newest GLM-5 generation, a very large MoE for advanced reasoning and tool use, with a 1M-token context. It is a frontier-scale model, which makes the local question blunt: for almost everyone, you do not run this on your own hardware. Here is exactly why, and the cheaper path.
The short answer
Only the largest machines we track can hold GLM-5.2, and only at a heavy quant. Here are the ones that fit: For a model this size, renting a cloud GPU or using a hosted API is almost always the saner option.
| Machine | Memory | Quant | Weights | ~tok/s |
|---|---|---|---|---|
| Mac Studio, 512GB unified (Ultra) | 512 GB (unified) | Q4_K_M | ~451.8 GB | ~2 tok/s |
The memory math
Weights scale with parameters. At Q4_K_M (about 4.8 bits) GLM-5.2 is roughly 452 GB of weights; squeezed to a low-quality Q2 it is still about 315 GB, before you add the KV cache and overhead. That puts it in a multi-GPU server or two 512 GB Mac Studios territory, not consumer hardware. The VRAM guide and the quantization guide walk through the trade-offs.
Or just rent it (the realistic option)
At this scale, renting a GPU by the hour or calling a hosted API almost always beats buying. Our cost calculator does the buy-versus-rent-versus-API math for your actual usage, so you can see the break-even instead of guessing.
