DeepSeek LLM 67B needs ~52.4 GB VRAM. RTX 6000 Ada 48GB has 48.0 GB. With Q4_K_M quantization, expect ~13 tok/s.
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.

Offload
10%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 3.4 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RTX 6000 Ada 48GB can run DeepSeek LLM 67B with a C grade (Very compromised (needs ~3.4 GB host RAM)). Expected decode speed: 13.1 tok/s.
DeepSeek LLM 67B (67B parameters) requires approximately 52.4 GB of memory with Q4_K_M quantization.
The recommended quantization for DeepSeek LLM 67B is Q4_K_M, which balances quality and memory efficiency.
On RTX 6000 Ada 48GB, DeepSeek LLM 67B achieves approximately 13.1 tokens per second decode speed with a time-to-first-token of 14803ms using Q4_K_M quantization.
For coding workloads, DeepSeek LLM 67B on RTX 6000 Ada 48GB receives a C grade with 13.1 tok/s and 4K context.
On RTX 6000 Ada 48GB, DeepSeek LLM 67B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.
