Qwen3 14B

Qwen3 14B needs roughly 11.6 GB VRAM at Q4_K_M quantization (34.7 GB at FP16). 93 GPUs we track can run it fully in VRAM at 8k context.

Qwen3 14B is a 14.8B parameter dense model developed by Alibaba. April 2025 dense model from the Qwen3 line, released under Apache 2.0 with a unified thinking/non-thinking mode toggled via the chat template or an enable_thinking flag.

To run Qwen3 14B locally: Q5_K_M needs roughly 10-11GB — fits on a 12GB GPU with some headroom, or comfortably on 16GB. Thinking mode generates longer outputs, so budget extra KV cache for reasoning-heavy prompts.

MMLU-Pro 61.03 puts it well ahead of Qwen2.5-14B on general reasoning, reflecting Qwen3's larger 36-trillion-token pretraining corpus.

VRAM at each quantization

Qwen3 14B natively supports a longer context window, but the table below is capped at 8k for comparability — KV cache grows linearly with context length.
