Frequently Asked Questions
How much VRAM does Deepseek Coder 6.7B Kexer need?
Deepseek Coder 6.7B Kexer requires 5.4 GB of VRAM at Q4_K_M, or 14.8 GB at BF16. Full 16K context adds up to 7.5 GB (12.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 6.7B × 4.8 bits ÷ 8 = 4 GB
KV Cache + Overhead ≈ 1.4 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 ≈ 8.9 GB (at full 16K context)
VRAM usage by quantization
What's the best quantization for Deepseek Coder 6.7B Kexer?
For Deepseek Coder 6.7B Kexer, Q4_K_M (5.4 GB) offers the best balance of quality and VRAM usage. Q5_K_M (6.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 4.2 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Deepseek Coder 6.7B Kexer on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Deepseek Coder 6.7B Kexer. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 5.4 GB of usable unified memory (RAM minus macOS overhead).
Can I run Deepseek Coder 6.7B Kexer locally?
Yes — Deepseek Coder 6.7B Kexer can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Deepseek Coder 6.7B Kexer?
At Q4_K_M, Deepseek Coder 6.7B Kexer can reach ~886 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~121 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 ÷ 5.42 × 0.65 = ~959 tok/s
Estimated speed at Q4_K_M (5.4 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Deepseek Coder 6.7B Kexer?
At Q4_K_M, the download is about 4.04 GB. The full-precision BF16 version is 13.48 GB. The smallest option (Q2_K) is 2.86 GB.
