NousResearch Hermes 4 14B needs ~8.8 GB VRAM. RX 6600 XT 8GB has 8.0 GB. With Q2_K quantization, expect ~12 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
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 0.5 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RX 6600 XT 8GB can run NousResearch Hermes 4 14B at Q2_K quantization (Very compromised (needs ~0.5 GB host RAM)). The recommended Q4_K_M requires 11.9 GB which exceeds available memory, but at Q2_K it needs only 8.8 GB. Expected decode speed: 12.2 tok/s.
NousResearch Hermes 4 14B (14B parameters) requires approximately 11.9 GB at Q4_K_M quantization. On RX 6600 XT 8GB, it fits at Q2_K using 8.8 GB.
The recommended quantization is Q4_K_M, but on RX 6600 XT 8GB the best fitting quantization is Q2_K, which uses 8.8 GB.
On RX 6600 XT 8GB, NousResearch Hermes 4 14B achieves approximately 12.2 tokens per second decode speed with a time-to-first-token of 15835ms using Q2_K quantization.
For coding workloads, NousResearch Hermes 4 14B on RX 6600 XT 8GB receives a F grade with 4.9 tok/s and 4K context.
On RX 6600 XT 8GB, NousResearch Hermes 4 14B can safely use up to 8K tokens of context at Q2_K quantization. The model's official context limit is —, 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.
