DeepSeek V3.2 needs ~419.0 GB but NVIDIA H100 80GB only has 80.0 GB. Try a smaller quantization or lighter model.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 419.0 GB, but this setup only exposes 80.0 GB of usable VRAM.
Add more VRAM headroom
The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.

No, DeepSeek V3.2 requires more memory than NVIDIA H100 80GB provides.
DeepSeek V3.2 (671B parameters) requires approximately 419.0 GB of memory with Q4_K_M quantization.
The recommended quantization for DeepSeek V3.2 is Q4_K_M, which balances quality and memory efficiency.
On NVIDIA H100 80GB, DeepSeek V3.2 achieves approximately 3.3 tokens per second decode speed with a time-to-first-token of 58771ms using Q4_K_M quantization.
For coding workloads, DeepSeek V3.2 on NVIDIA H100 80GB receives a F grade with 3.3 tok/s and 4K context.
On NVIDIA H100 80GB, DeepSeek V3.2 can safely use up to 4K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.
Add more VRAM headroom. The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.
