Magistral Small 2507 needs ~18.7 GB VRAM. Tesla P100 16GB has 16.0 GB. With NVFP4 quantization, expect ~19 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.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Offload
20%
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.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
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 1.9 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, Tesla P100 16GB can run Magistral Small 2507 at NVFP4 quantization (Very compromised (needs ~1.9 GB host RAM)). The recommended Q4_K_M requires 19.9 GB which exceeds available memory, but at NVFP4 it needs only 18.7 GB. Expected decode speed: 18.8 tok/s.
Magistral Small 2507 (24B parameters) requires approximately 19.9 GB at Q4_K_M quantization. On Tesla P100 16GB, it fits at NVFP4 using 18.7 GB.
The recommended quantization is Q4_K_M, but on Tesla P100 16GB the best fitting quantization is NVFP4, which uses 18.7 GB.
On Tesla P100 16GB, Magistral Small 2507 achieves approximately 18.8 tokens per second decode speed with a time-to-first-token of 10283ms using NVFP4 quantization.
For coding workloads, Magistral Small 2507 on Tesla P100 16GB receives a F grade with 14.4 tok/s and 4K context.
On Tesla P100 16GB, Magistral Small 2507 can safely use up to 4K tokens of context at NVFP4 quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.
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.
