FAQ
Can the NVIDIA RTX 4070 Ti run Qwen3 VL 8B Thinking?
Yes. The NVIDIA RTX 4070 Ti's 12.0GB of VRAM is enough to run Qwen3 VL 8B Thinking at Q8_0 quantization (10.3GB required).
What's the best quantization to use?
Q8_0 is the highest-precision quantization that fits in your 12.0GB. It uses about 10.3GB of memory and 11.8GB 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.
