Nous Hermes 1.0 needs ~18.5 GB VRAM. RTX 4080 Super 16GB has 16.0 GB. With Q2_K quantization, expect ~82 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 0.5 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RTX 4080 Super 16GB can run Nous Hermes 1.0 at Q2_K quantization (Very compromised (needs ~0.5 GB host RAM)). The recommended Q4_K_M requires 20.5 GB which exceeds available memory, but at Q2_K it needs only 18.5 GB. Expected decode speed: 81.6 tok/s.
Nous Hermes 1.0 (9B parameters) requires approximately 20.5 GB at Q4_K_M quantization. On RTX 4080 Super 16GB, it fits at Q2_K using 18.5 GB.
The recommended quantization is Q4_K_M, but on RTX 4080 Super 16GB the best fitting quantization is Q2_K, which uses 18.5 GB.
On RTX 4080 Super 16GB, Nous Hermes 1.0 achieves approximately 81.6 tokens per second decode speed with a time-to-first-token of 2373ms using Q2_K quantization.
For coding workloads, Nous Hermes 1.0 on RTX 4080 Super 16GB receives a F grade with 49.5 tok/s and 10K context.
On RTX 4080 Super 16GB, Nous Hermes 1.0 can safely use up to 13K tokens of context at Q2_K quantization. The model's official context limit is 16K, 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.
