VRAM needed to run them
GPU memory at the lowest released precision. Each user needs their own KV cache, so memory grows with users and context length.

Which GPUs can run DeepSeek-V4-Pro and GLM-5.1
Smallest setup on each system, with 8K context per user. Green fits on one GPU or system, amber needs several in one server, grey needs more than one 8-GPU server.

Setups in amber or grey need several GPUs or servers working as one. Buying the GPUs is the easy part. Vanik Edge OS splits the model across them, keeps it running if a server fails and manages it all from one console. See how Edge OS clusters GPU servers
Which is faster?
On the same hardware, GLM-5.1 should generate tokens about 1.2× faster for each user: it reads about 23 GB of weights per token (40B active at NVFP4) versus 28 GB for DeepSeek-V4-Pro. Token generation is limited mostly by memory bandwidth, so fewer active bytes means faster replies. Real throughput also depends on batching, the inference engine and the GPU.
FROM SIZING TO RUNNING
Sizing the hardware is the easy part.
Getting several GPUs to work as one system for a whole company is where most projects slow down. That is the part Vanik Edge OS does for you.
STEP 01 · THIS TOOL

DeepSeek-V4-Pro vs GLM-5.1 questions
What is the difference between DeepSeek-V4-Pro and GLM-5.1?
DeepSeek-V4-Pro has 1.6T parameters (49B active) and a 1M-token context; GLM-5.1 has 754B (40B active) and up to 200K. Both use the MIT license. GLM-5.1 has since been followed by GLM-5.2 and GLM-5.3.
DeepSeek-V4-Pro vs GLM-5.1: which is better to run on-premise?
Choose DeepSeek-V4-Pro if you need a 1M-token context and DeepSeek’s largest model. Choose GLM-5.1 if you already run GLM-5.1 and are happy with it; otherwise look at GLM-5.2 or GLM-5.3, which are newer.
Which needs less VRAM, DeepSeek-V4-Pro or GLM-5.1?
GLM-5.1. For one user with 8K context it needs about 461 GB, versus about 976 GB for DeepSeek-V4-Pro. For 16 users it needs about 473 GB versus 977 GB.
Which is faster, DeepSeek-V4-Pro or GLM-5.1?
On the same hardware, GLM-5.1 should generate tokens about 1.2× faster for each user: it reads about 23 GB of weights per token (40B active at NVFP4) versus 28 GB for DeepSeek-V4-Pro. Token generation is limited mostly by memory bandwidth, so fewer active bytes means faster replies.
Can I run DeepSeek-V4-Pro locally?
Yes. At FP4 + FP8 it needs about 976 GB of GPU memory for one user with 8K context, which fits on 8 × NVIDIA H200 NVL. A team of 16 needs about 977 GB: 8 × NVIDIA H200 NVL.
Can I run GLM-5.1 locally?
Yes. At NVFP4 it needs about 461 GB of GPU memory for one user with 8K context, which fits on 4 × NVIDIA H200 NVL. A team of 16 needs about 473 GB: 4 × NVIDIA H200 NVL.
Can I use DeepSeek-V4-Pro and GLM-5.1 commercially?
DeepSeek-V4-Pro is released under MIT. GLM-5.1 is released under MIT. Check each license before a commercial deployment.
How are these numbers calculated?
Memory figures come from our VRAM calculator method: weights at the lowest released precision, plus the KV cache for each user’s context, plus about 5 to 10% runtime overhead, keeping 10% of each GPU free. Where a developer does not publish the cache size we estimate it from the architecture. These are planning estimates, not benchmarks.
