What AI models can you run with 6GB of VRAM?

With 6GB of VRAM, 106 of 225 catalog builds have good/excellent reference fits at 4K context. 91 more run by offloading part of the model to system RAM, which works but is slower.

Leave room for the conversation

A 6 GB card can have little headroom after loading some 7–8B builds. Compare a smaller instruct model with the larger option at 4K and 8K context before committing to a download.

Quantization compresses weights; it does not remove context-cache or runtime costs. Compare the same model at Q4 and Q8 in the calculator, then validate its output on your task. Training and fine-tuning need a different memory budget.

Models that fit — largest memory first — for 6GB of VRAM

Heaviest first — each of these has a good/excellent reference fit with 6GB at 4K context, counting weights, KV cache, compute buffers and runtime overhead.

How this was calculated

Every model is evaluated at 4K context against 6GB of VRAM, minus a reserve for the display and operating system, and assuming 32GB of system RAM with an illustrative 8-core/16-thread CPU and 500GB free disk. Available RAM and GPU budget/free memory are unknown. A working Vulkan backend on Windows is assumed; this is a capacity scenario, not a claim that all cards with this much memory have the same support. Your own machine may differ, which is what the PC scan measures directly.

6GB VRAM and local AI — frequently asked questions

Is 6GB of VRAM enough to run AI models locally?
Yes — 106 of the 225 builds evaluated have good/excellent reference fits with 6GB at 4K context, and 91 more run with part of the model offloaded to system RAM. The heaviest that fits is codeqwen:7b-chat-v1.5-q4_K_M, needing about 5.4 GB.
How should I choose a model for 6GB VRAM?
Choose for your task, then check memory. codeqwen (codeqwen:7b-chat-v1.5-q4_K_M) is the heaviest catalog default that fits this reference budget; its size does not establish answer quality. Smaller models leave headroom for a longer context window, which often matters more than raw parameter count.
Which graphics cards have 6GB of VRAM?
Several cards ship with 6GB of VRAM across NVIDIA and AMD ranges.
