FAQ
Can the NVIDIA GTX 1660 Ti run Qwen3 VL 8B Instruct?
Yes. The NVIDIA GTX 1660 Ti's 6.0GB of VRAM is enough to run Qwen3 VL 8B Instruct at Q4_0 quantization (6.0GB required).
What's the best quantization to use?
Q4_0 is the highest-precision quantization that fits in your 6.0GB. It uses about 6.0GB of memory and 7.5GB 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.
