Magistral Small 2507 needs ~18.7 GB VRAM. NVIDIA A2 16GB has 16.0 GB. With NVFP4 quantization, expect ~7 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.
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, NVIDIA A2 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: 7.1 tok/s.
Magistral Small 2507 (24B parameters) requires approximately 19.9 GB at Q4_K_M quantization. On NVIDIA A2 16GB, it fits at NVFP4 using 18.7 GB.
The recommended quantization is Q4_K_M, but on NVIDIA A2 16GB the best fitting quantization is NVFP4, which uses 18.7 GB.
On NVIDIA A2 16GB, Magistral Small 2507 achieves approximately 7.1 tokens per second decode speed with a time-to-first-token of 27300ms using NVFP4 quantization.
For coding workloads, Magistral Small 2507 on NVIDIA A2 16GB receives a F grade with 5.4 tok/s and 4K context.
On NVIDIA A2 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.
