Falcon 40B Instruct needs ~27.8 GB VRAM. NVIDIA A10 24GB has 24.0 GB. With NVFP4 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
30%
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 3.1 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, NVIDIA A10 24GB can run Falcon 40B Instruct at NVFP4 quantization (Very compromised (needs ~3.1 GB host RAM)). The recommended Q5_K_M requires 34.2 GB which exceeds available memory, but at NVFP4 it needs only 27.8 GB. Expected decode speed: 13.1 tok/s.
Falcon 40B Instruct (40B parameters) requires approximately 34.2 GB at Q5_K_M quantization. On NVIDIA A10 24GB, it fits at NVFP4 using 27.8 GB.
The recommended quantization is Q5_K_M, but on NVIDIA A10 24GB the best fitting quantization is NVFP4, which uses 27.8 GB.
On NVIDIA A10 24GB, Falcon 40B Instruct achieves approximately 13.1 tokens per second decode speed with a time-to-first-token of 14778ms using NVFP4 quantization.
For coding workloads, Falcon 40B Instruct on NVIDIA A10 24GB receives a F grade with 6.4 tok/s and 4K context.
On NVIDIA A10 24GB, Falcon 40B Instruct can safely use up to 4K tokens of context at NVFP4 quantization. The model's official context limit is 8K, but available memory constrains the safe maximum.
