Hermes 4.3 36B GGUF Size & VRAM Requirements
Hermes-4.3-36B-GGUF is a very large language model focused on general purpose & instruction. With approximately 36.15 billion parameters, it balances local hardware requirements with reasoning and generation fidelity. It is built on the seed_oss architecture with a native context window of up to 524,288 tokens. The model is primarily recommended for general knowledge, document summarization, email drafting, language translation, and multi-turn conversational chat. Released under the apache-2.0 license, it can be executed fully offline without sending data to external APIs.
Under the hood it uses 64 transformer layers, a hidden size of 5,120, 80 attention heads. It uses grouped-query attention (80 query heads sharing 8 key/value heads), which already trims KV-cache memory compared with full multi-head attention.
To run NousResearch/Hermes-4.3-36B-GGUF locally at a 4,096-token context, its quantized versions need between 18.21 GB (Q3_K_M, lowest quality) and 69.15 GB (GGUF, 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 Hermes-4.3-36B-GGUF is about 1.0 GB, rising to roughly 128.0 GB at its full 524,288-token context. Shorter prompts free up memory for a higher-quality quantization.
For most users the best balance is Q4_K_M, needing about 22.07 GB. That means NousResearch/Hermes-4.3-36B-GGUF fits entirely in the VRAM of a 24 GB GPU or larger, running fully on the GPU.
Available GGUF quantizations for NousResearch/Hermes-4.3-36B-GGUF include Q3_K_M, Q4_K_M, Q5_K_M, Q6_K, Q8_0, GGUF. The model supports a native context length of up to 524,288 tokens; a longer context grows the KV cache and the memory needed.

Frequently asked questions
What kind of model is NousResearch/Hermes-4.3-36B-GGUF?
NousResearch/Hermes-4.3-36B-GGUF is a language model with 36.15 billion parameters, based on the seed_oss architecture. It is released under the apache-2.0 license and distributed as GGUF files for local inference.
How much VRAM do you need to run NousResearch/Hermes-4.3-36B-GGUF?
You need about 22.07 GB of VRAM to run NousResearch/Hermes-4.3-36B-GGUF entirely on the GPU using the Q4_K_M quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run NousResearch/Hermes-4.3-36B-GGUF on an 8 GB GPU?
Partially. NousResearch/Hermes-4.3-36B-GGUF only fits on an 8 GB GPU by offloading part of it to system RAM (with Q4_K_M), which runs but is slower.
Can I run NousResearch/Hermes-4.3-36B-GGUF on a 16 GB GPU?
Partially. NousResearch/Hermes-4.3-36B-GGUF only fits on a 16 GB GPU by offloading part of it to system RAM (with Q8_0), which runs but is slower.
Can I run NousResearch/Hermes-4.3-36B-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run NousResearch/Hermes-4.3-36B-GGUF fully on the GPU using Q4_K_M (about 22.07 GB).
What context length does NousResearch/Hermes-4.3-36B-GGUF support?
NousResearch/Hermes-4.3-36B-GGUF supports a native context length of up to 524,288 tokens. A longer context grows the KV cache, so it increases the memory needed to run the model.
What is the best quantization for NousResearch/Hermes-4.3-36B-GGUF?
For NousResearch/Hermes-4.3-36B-GGUF, a strong default is Q4_K_M, which needs about 22.07 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.
