grok-oss-Revenant-70B-i1 GGUF size and VRAM requirements
mradermacher/grok-oss-Revenant-70B-i1-GGUF is a very large language model with 70.55 billion parameters, built on the llama architecture. It is released under the other license and has been downloaded 11,533 times.
To run mradermacher/grok-oss-Revenant-70B-i1-GGUF locally at a 4,096-token context, its quantized versions need between 4.88 GB (GGUF, lowest quality) and 58.77 GB (Q6_K, highest quality) of memory, weights plus KV cache and a system margin included.
For most users the best balance is GGUF, needing about 4.88 GB. That means mradermacher/grok-oss-Revenant-70B-i1-GGUF fits entirely in the VRAM of a 6 GB GPU or larger, running fully on the GPU.

Frequently asked questions
How much VRAM do you need to run mradermacher/grok-oss-Revenant-70B-i1-GGUF?
You need about 4.88 GB of VRAM to run mradermacher/grok-oss-Revenant-70B-i1-GGUF entirely on the GPU using the GGUF quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run mradermacher/grok-oss-Revenant-70B-i1-GGUF on an 8 GB GPU?
Yes. With 8 GB of VRAM you can run mradermacher/grok-oss-Revenant-70B-i1-GGUF fully on the GPU using GGUF (about 4.88 GB).
Can I run mradermacher/grok-oss-Revenant-70B-i1-GGUF on a 16 GB GPU?
Yes. With 16 GB of VRAM you can run mradermacher/grok-oss-Revenant-70B-i1-GGUF fully on the GPU using GGUF (about 4.88 GB).
Can I run mradermacher/grok-oss-Revenant-70B-i1-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run mradermacher/grok-oss-Revenant-70B-i1-GGUF fully on the GPU using IQ2_XXS (about 22.64 GB).
What is the best quantization for mradermacher/grok-oss-Revenant-70B-i1-GGUF?
If memory allows, higher bits-per-weight means better quality. A common sweet spot is a Q4_K_M or Q5_K_M quantization, which keeps most of the quality while roughly halving the memory versus 8-bit. Pick the highest quantization that still fits in your VRAM.
