All models that fit in 4 GB of VRAM

One entry per model, up to 30, sorted by popularity. For each model we show the largest (most precise) quantization that fits in this memory with a context of at least 8K tokens. The context length is the longest one that quantization fits (for models whose maximum is under 8K, such as embedding models, that maximum). Models that are not for chat or text generation are labelled with their use. "Left" is the memory minus the estimate; under 5% of the memory is marked "tight" (not a guarantee that it fits).

Frequently asked questions

Which local LLMs run in 4 GB of VRAM?
On this site, 277 models have a quantization that fits in 4 GB at 8,192 tokens (estimated). Popular ones include Ornith-1.5-9B, MOSS-Music-8B-Instruct, Qwen3.5-4B, Qwen3-4B, Ternary-Bonsai-2-9B.
What is the largest model that runs in 4 GB of VRAM?
Among the models listed here, Qwen3.8-Flash-Next-FP4-Local-Strata (about 51.2B). With BF16 it needs an estimated 2.66 GB at 8,192 tokens. Smaller quantizations lower quality.
Is it the same for a Mac with 4 GB of unified memory?
macOS limits how much memory the GPU can use, so not all 4 GB is available to the model. On a Mac, leave headroom over the required memory.
What happens with a longer context?
The KV cache grows, so the required memory grows too. Each model page shows estimated memory for each context length.
