NousResearch_Hermes-4-14B GGUF size and VRAM requirements
bartowski/NousResearch_Hermes-4-14B-GGUF is a language model, built on the qwen3 architecture. It has been downloaded 16,087 times.
Under the hood it uses 40 transformer layers, a hidden size of 5,120, 40 attention heads. It uses grouped-query attention (40 query heads sharing 8 key/value heads), which already trims KV-cache memory compared with full multi-head attention.
To run bartowski/NousResearch_Hermes-4-14B-GGUF locally at a 4,096-token context, its quantized versions need between 5.79 GB (IQ2_XS, lowest quality) and 28.94 GB (BF16, highest quality) of memory, weights plus KV cache and a system margin included. Context length drives that memory directly: at 4,096 tokens the KV cache for NousResearch_Hermes-4-14B-GGUF is about 0.62 GB, rising to roughly 6.25 GB at its full 40,960-token context. Shorter prompts free up memory for a higher-quality quantization.
For most users the best balance is IQ3_M, needing about 7.84 GB. That means bartowski/NousResearch_Hermes-4-14B-GGUF fits entirely in the VRAM of a 6 GB GPU or larger, running fully on the GPU.
Available GGUF quantizations for bartowski/NousResearch_Hermes-4-14B-GGUF include IQ2_XS, IQ2_S, IQ2_M, Q2_K, IQ3_XXS, IQ3_XS, Q2_K_L, Q3_K_S, IQ3_M, Q3_K_M, Q3_K_L, IQ4_XS, IQ4_NL, Q4_0, Q4_K_S, Q3_K_XL, Q4_K_M, Q4_1, Q4_K_L, Q5_K_S, Q5_K_M, Q5_K_L, Q6_K, Q6_K_L, Q8_0, BF16. The model supports a native context length of up to 40,960 tokens; a longer context grows the KV cache and the memory needed.

Frequently asked questions
What kind of model is bartowski/NousResearch_Hermes-4-14B-GGUF?
bartowski/NousResearch_Hermes-4-14B-GGUF is a language model, based on the qwen3 architecture. It is distributed as GGUF files for local inference.
How much VRAM do you need to run bartowski/NousResearch_Hermes-4-14B-GGUF?
You need about 5.79 GB of VRAM to run bartowski/NousResearch_Hermes-4-14B-GGUF entirely on the GPU using the IQ2_XS quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run bartowski/NousResearch_Hermes-4-14B-GGUF on an 8 GB GPU?
Yes. With 8 GB of VRAM you can run bartowski/NousResearch_Hermes-4-14B-GGUF fully on the GPU using IQ3_M (about 7.84 GB).
Can I run bartowski/NousResearch_Hermes-4-14B-GGUF on a 16 GB GPU?
Yes. With 16 GB of VRAM you can run bartowski/NousResearch_Hermes-4-14B-GGUF fully on the GPU using Q6_K_L (about 13.07 GB).
Can I run bartowski/NousResearch_Hermes-4-14B-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run bartowski/NousResearch_Hermes-4-14B-GGUF fully on the GPU using Q8_0 (about 16.05 GB).
What context length does bartowski/NousResearch_Hermes-4-14B-GGUF support?
bartowski/NousResearch_Hermes-4-14B-GGUF supports a native context length of up to 40,960 tokens. A longer context grows the KV cache, so it increases the memory needed to run the model.
What is the best quantization for bartowski/NousResearch_Hermes-4-14B-GGUF?
For bartowski/NousResearch_Hermes-4-14B-GGUF, a strong default is Q4_K_M, which needs about 9.81 GB and keeps most of the quality while roughly halving the memory versus 8-bit. With VRAM to spare, Q5_K_M or Q6_K add a little more quality; if you are tight on memory, a smaller quantization still runs. Pick the highest quantization that fits your VRAM.
