Hermes 4.3 36B needs ~28.0 GB VRAM. RTX 3090 Ti 24GB has 24.0 GB. With NVFP4 quantization, expect ~20 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
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 2.9 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RTX 3090 Ti 24GB can run Hermes 4.3 36B at NVFP4 quantization (Very compromised (needs ~2.9 GB host RAM)). The recommended Q4_K_M requires 29.8 GB which exceeds available memory, but at NVFP4 it needs only 28.0 GB. Expected decode speed: 20.2 tok/s.
Hermes 4.3 36B (36B parameters) requires approximately 29.8 GB at Q4_K_M quantization. On RTX 3090 Ti 24GB, it fits at NVFP4 using 28.0 GB.
The recommended quantization is Q4_K_M, but on RTX 3090 Ti 24GB the best fitting quantization is NVFP4, which uses 28.0 GB.
On RTX 3090 Ti 24GB, Hermes 4.3 36B achieves approximately 20.2 tokens per second decode speed with a time-to-first-token of 9564ms using NVFP4 quantization.
For coding workloads, Hermes 4.3 36B on RTX 3090 Ti 24GB receives a F grade with 15.5 tok/s and 4K context.
On RTX 3090 Ti 24GB, Hermes 4.3 36B can safely use up to 4K tokens of context at NVFP4 quantization. The model's official context limit is —, but available memory constrains the safe maximum.
