Only just. Qwen3 14B fits on the NVIDIA RTX 3070 at Q2_K, which costs noticeable quality. Expect about 48 tokens/second. A card with more memory is a better experience.

Try other context lengths

Run it with Ollama

Ollama's default qwen3:14b download is Q4_K_M, which needs about 10.9 GB, more than the 8 GB available. Download the Q2_K GGUF instead (LM Studio lists quants per model), or try a smaller context length.
