Frequently Asked Questions
How much VRAM does Qwen2.5 14B Instruct 1M need?
Qwen2.5 14B Instruct 1M requires 9.6 GB of VRAM at Q4_K_M, or 30.2 GB at BF16. Full 1010K context adds up to 198.2 GB (207.7 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 14.8B × 4.8 bits ÷ 8 = 8.9 GB
KV Cache + Overhead ≈ 0.7 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 198.8 GB (at full 1010K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Qwen2.5 14B Instruct 1M?
Yes, at Q8_0 (15.5 GB) or lower. Higher quantizations like BF16 (30.2 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Qwen2.5 14B Instruct 1M?
For Qwen2.5 14B Instruct 1M, Q4_K_M (9.6 GB) offers the best balance of quality and VRAM usage. Q5_K_M (11.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 7.0 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Qwen2.5 14B Instruct 1M on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Qwen2.5 14B Instruct 1M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 9.6 GB of usable unified memory (RAM minus macOS overhead).
Can I run Qwen2.5 14B Instruct 1M locally?
Yes — Qwen2.5 14B Instruct 1M can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Qwen2.5 14B Instruct 1M?
At Q4_K_M, Qwen2.5 14B Instruct 1M can reach ~502 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~69 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 9.56 × 0.65 = ~544 tok/s
Estimated speed at Q4_K_M (9.6 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Qwen2.5 14B Instruct 1M?
At Q4_K_M, the download is about 8.86 GB. The full-precision BF16 version is 29.54 GB. The smallest option (Q2_K) is 6.28 GB.
