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.

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.

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.

  1. STEP 01 · THIS TOOL

    Size it

    Work out the GPU memory your models need and which GPUs or servers can hold them.

  2. STEP 02 · VANIK EDGE OS

    Cluster it

    Edge OS joins your GPU servers into one cluster, splits a large model across them and keeps it running if a server fails. NVIDIA and AMD servers work side by side.

  3. STEP 03 · VANIK EDGE OS

    Run it

    Your team gets AI apps with single sign-on and an audit trail, managed from one console, with your data staying inside your building.

DeepSeek-V3.2 vs DeepSeek-V4-Flash questions

What is the difference between DeepSeek-V3.2 and DeepSeek-V4-Flash?

DeepSeek-V4-Flash is the newer, smaller design: 284B parameters with 13B active and a 1M-token context, versus 685B with 37B active and 128K for V3.2. Flash needs less than half the memory.

DeepSeek-V3.2 vs DeepSeek-V4-Flash: which is better to run on-premise?

Choose DeepSeek-V3.2 if you have already validated V3.2 in production and only need a 128K context. Choose DeepSeek-V4-Flash if you are starting now: it is newer, needs far less memory, has an 8× longer context and generates tokens faster.

Which needs less VRAM, DeepSeek-V3.2 or DeepSeek-V4-Flash?

DeepSeek-V4-Flash. For one user with 8K context it needs about 177 GB, versus about 419 GB for DeepSeek-V3.2. For 16 users it needs about 178 GB versus 428 GB.

Which is faster, DeepSeek-V3.2 or DeepSeek-V4-Flash?

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.

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.
