Wanabi-Novelist-24B GGUF size and VRAM requirements
mradermacher/Wanabi-Novelist-24B-GGUF is a large language model with 23.57 billion parameters, built on the llama architecture. It is released under the apache-2.0 license and has been downloaded 15,217 times.
Under the hood it uses 40 transformer layers, a hidden size of 5,120, 32 attention heads. It uses grouped-query attention (32 query heads sharing 8 key/value heads), which already trims KV-cache memory compared with full multi-head attention.
To run mradermacher/Wanabi-Novelist-24B-GGUF locally at a 4,096-token context, its quantized versions need between 9.7 GB (Q2_K, lowest quality) and 24.76 GB (Q8_0, 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 Wanabi-Novelist-24B-GGUF is about 0.62 GB, rising to roughly 20.0 GB at its full 131,072-token context. Shorter prompts free up memory for a higher-quality quantization.
For most users the best balance is Q6_K, needing about 19.44 GB. That means mradermacher/Wanabi-Novelist-24B-GGUF fits entirely in the VRAM of a 10 GB GPU or larger, running fully on the GPU.
Available GGUF quantizations for mradermacher/Wanabi-Novelist-24B-GGUF include Q2_K, Q3_K_S, Q3_K_M, Q3_K_L, IQ4_XS, Q4_K_S, Q4_K_M, Q5_K_S, Q5_K_M, Q6_K, Q8_0. The model supports a native context length of up to 131,072 tokens; a longer context grows the KV cache and the memory needed.

Frequently asked questions
What kind of model is mradermacher/Wanabi-Novelist-24B-GGUF?
mradermacher/Wanabi-Novelist-24B-GGUF is a language model with 23.57 billion parameters, based on the llama 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 mradermacher/Wanabi-Novelist-24B-GGUF?
You need about 9.7 GB of VRAM to run mradermacher/Wanabi-Novelist-24B-GGUF entirely on the GPU using the Q2_K quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run mradermacher/Wanabi-Novelist-24B-GGUF on an 8 GB GPU?
Partially. mradermacher/Wanabi-Novelist-24B-GGUF only fits on an 8 GB GPU by offloading part of it to system RAM (with Q6_K), which runs but is slower.
Can I run mradermacher/Wanabi-Novelist-24B-GGUF on a 16 GB GPU?
Yes. With 16 GB of VRAM you can run mradermacher/Wanabi-Novelist-24B-GGUF fully on the GPU using Q4_K_M (about 14.77 GB).
Can I run mradermacher/Wanabi-Novelist-24B-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run mradermacher/Wanabi-Novelist-24B-GGUF fully on the GPU using Q6_K (about 19.44 GB).
What context length does mradermacher/Wanabi-Novelist-24B-GGUF support?
mradermacher/Wanabi-Novelist-24B-GGUF supports a native context length of up to 131,072 tokens. A longer context grows the KV cache, so it increases the memory needed to run the model.
What is the best quantization for mradermacher/Wanabi-Novelist-24B-GGUF?
For mradermacher/Wanabi-Novelist-24B-GGUF, a strong default is Q4_K_M, which needs about 14.77 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.
