Only just. Gemma 4 12B fits on the NVIDIA RTX 3070 at Q3_K_M, which costs noticeable quality. Expect about 46 tokens/second. A card with more memory is a better experience.

Try other context lengths

Run it with Ollama

Ollama's default gemma4:12b download is Q4_K_M, which needs about 8.3 GB, more than the 8 GB available. Download the Q3_K_M GGUF instead (LM Studio lists quants per model), or try a smaller context length.
