How much VRAM does Gemma 2 2B Instruct need?

About 2.1 GB at Q4_K_M with 4K of context and batch 1, rising to roughly 3.7 GB at 32K. That figure is weights plus KV cache plus a 10% activation buffer, calculated from the model's architecture rather than measured on a card.

Will Gemma 2 2B Instruct run on a 8GB GPU?

Yes — at Q4_K_M and 4K context it needs about 2.1 GB, which leaves 3.9 GB spare on a Mac M1 8G, or on any of the other 8 GB cards here (11 in all). That is the smallest size in this index that clears it comfortably; 78 of 78 do.

Which quantization of Gemma 2 2B Instruct should I use?

Q8_0 has the lowest published quality loss (0.3%), and Q4_K_M is the level most people run. All 3 levels in the index are Q4_K_M, Q8_0, AWQ INT4.

⚠ Superseded · Prefer Gemma 4 E2B IT

This index would suggest Gemma 4 E2B IT instead today — longer context (8K → 128K tokens). The numbers below are still accurate; they are just for a model you probably should not start with. Compare the two →

Ultra-compact Gemma 2. Runs on 4GB VRAM; great for edge prototyping.

Which file each size is for

A file size is not a memory figure: the VRAM column is the calculator's total at 4K context — weights plus KV cache plus a 10% activation buffer. Units differ on purpose: file sizes are decimal GB, as Hugging Face lists them; the VRAM column is GiB (1024³ bytes) with 2% added to the weights, so 7.12 GB of file counts as about 6.8 GiB there. A vision projector (mmproj), where the repo ships one, is a separate download and is in neither number.

Running Gemma 2 2B Instruct locally

At Q4_K_M and 4K of context, Gemma 2 2B Instruct needs about 2.1 GB — 1.5 GB of weights, 0.41 GB of KV cache and a 0.2 GB activation buffer. The smallest cards in this index that clear that comfortably are 8 GB ones — 11 of them, from the Mac M1 8G up — and 78 of the 78 cards here do. These are calculated figures, not measurements: the estimate stops counting a card as comfortable at 88% of its VRAM, which is roughly the room a desktop session needs.

What longer context costs

Going from 4K to 32K adds about 1.44 GB, taking the total to 3.7 GB. That is gentler than the parameter count suggests: only 13 of 26 layers keep a KV cache that grows with context, and 13 more cap theirs at a sliding window, so the cache scales at a fraction of the usual rate. The model's native window is 8K; holding all of it at Q4_K_M would need about 2 GB.

Which build to download

This index tracks 2 formats for it — GGUF, AWQ — across 3 levels. Q8_0 carries the lowest published perplexity loss at 0.3%. The fastest level listed is AWQ INT4 at about 450 tok/s on an RTX 4090, batch 1 — an estimate, not a run on this site's hardware. GGUF runs on llama.cpp and Ollama across NVIDIA, AMD and Apple silicon; AWQ and GPTQ target vLLM on CUDA and ROCm; EXL2 is ExLlamaV2 — CUDA only, and now archived, so local use rather than serving.

Common questions

How much VRAM does Gemma 2 2B Instruct need?: About 2.1 GB at Q4_K_M with 4K of context and batch 1, rising to roughly 3.7 GB at 32K. That figure is weights plus KV cache plus a 10% activation buffer, calculated from the model's architecture rather than measured on a card.
Will Gemma 2 2B Instruct run on a 8GB GPU?: Yes — at Q4_K_M and 4K context it needs about 2.1 GB, which leaves 3.9 GB spare on a Mac M1 8G, or on any of the other 8 GB cards here (11 in all). That is the smallest size in this index that clears it comfortably; 78 of 78 do.
Which quantization of Gemma 2 2B Instruct should I use?: Q8_0 has the lowest published quality loss (0.3%), and Q4_K_M is the level most people run. All 3 levels in the index are Q4_K_M, Q8_0, AWQ INT4.

Where this model fits

Sized at Q4_K_M with a 4K context window, smallest card first. Comfortable means the estimate uses at most 88% of the memory.
