FAQ
Can the NVIDIA GTX 1660 Ti run Gemma 3n 4B?
Yes. The NVIDIA GTX 1660 Ti's 6.0GB of VRAM is enough to run Gemma 3n 4B at Q4_1 quantization (5.9GB required).
What's the best quantization to use?
Q4_1 is the highest-precision quantization that fits in your 6.0GB. It uses about 5.9GB of memory and 7.4GB recommended for comfortable inference.
What if I need more headroom for context length?
KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
