Qwen2.5 14B Instruct
Qwen2.5 14B Instruct loads in 11 GB at Q4_K_M, comfortably from 24 GB of memory — Macs included, starting at the Mac Mini M6 16GB. Below is the memory math we ran for it, the cheapest card that fits, and the fastest machine we track.
How much memory does Qwen2.5 14B Instruct need?
Qwen2.5 14B Instruct is a 14B dense model built for coding, chat. The weights alone take 11 GB at Q4_K_M; add context and the OS, and it belongs in the 24 GB memory class. Every number below comes from the ModelFit engine — speeds are estimates, labeled est., because we do not benchmark hardware ourselves.
KV = fp16 estimate (q8_0 cache roughly halves it). "Comfortable" = weights + KV within the engine's tiered budget (~70-85% of memory).
Which machines run Qwen2.5 14B Instruct?
Verdicts come from the same engine that powers our fit checker — memory capacity first, bandwidth for speed. How we compute these numbers · Hugging Face model card

Frequently asked questions
How much memory does Qwen2.5 14B Instruct need?
11 GB for the Q4_K_M weights, plus ~3.0 GB of KV-cache at 16k context — about 14.0 GB total. Comfortable from 24 GB of VRAM or unified memory.
Does Qwen2.5 14B Instruct run on a Mac?
Yes — from the Mac Mini M6 16GB (~15 tok/s est.). Unified memory means the RAM budget is the only limit.
What is the cheapest GPU for Qwen2.5 14B Instruct?
The AMD Radeon RX 7900 XT is the cheapest tracked card that runs Qwen2.5 14B Instruct comfortably — ~46 tok/s est. at ~$550 used.
