Which GPUs can run DeepSeek-V3.2 and DeepSeek-V4-Flash
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, DeepSeek-V4-Flash should generate tokens about 2.8× faster for each user: it reads about 7.7 GB of weights per token (13B active at FP4 + FP8) versus 21 GB for DeepSeek-V3.2. 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.

Can I run DeepSeek-V3.2 locally?
Yes. At NVFP4 it needs about 419 GB of GPU memory for one user with 8K context, which fits on 2 × AMD Instinct MI325X. A team of 16 needs about 428 GB: 2 × AMD Instinct MI325X.
Can I run DeepSeek-V4-Flash locally?
Yes. At FP4 + FP8 it needs about 177 GB of GPU memory for one user with 8K context, which fits on 2 × NVIDIA DGX Spark. A team of 16 needs about 178 GB: 2 × NVIDIA DGX Spark.
Can I use DeepSeek-V3.2 and DeepSeek-V4-Flash commercially?
DeepSeek-V3.2 is released under MIT. DeepSeek-V4-Flash 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.
