Can the RTX PRO 2000 Blackwell run OTel-2.0-LLM-31B-IT?
No. OTel-2.0-LLM-31B-IT needs about 20.8 GB at Q4_K_M (weights plus 1.8 GB runtime overhead), and the RTX PRO 2000 Blackwell has 16 GB, so it won't fit without offloading layers to system RAM, which is far slower.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 19 GB | 20.8 GB | Too big | - |
| Q5_K_M | 23 GB | 24.8 GB | Too big | - |
| Q8_0 | 34 GB | 35.8 GB | Too big | - |
| FP16 | 64 GB | 65.8 GB | Too big | - |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX PRO 2000 Blackwell's 288 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the RTX PRO 2000 Blackwell run OTel-2.0-LLM-31B-IT?
No. OTel-2.0-LLM-31B-IT needs about 20.8 GB at Q4_K_M (weights plus 1.8 GB runtime overhead), and the RTX PRO 2000 Blackwell has 16 GB, so it won't fit without offloading layers to system RAM, which is far slower.
How much VRAM does OTel-2.0-LLM-31B-IT need?
About 19 GB of weights at Q4_K_M, 34 GB at Q8_0 and 64 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is OTel-2.0-LLM-31B-IT on the RTX PRO 2000 Blackwell?
It doesn't fit in the RTX PRO 2000 Blackwell's memory, so speed depends on how many layers you offload to system RAM - typically single-digit tokens per second or lower.
