βš–οΈ The Pareto Frontier β€” Efficiency vs Intelligence

Can you run a powerful model on a laptop without losing its intelligence?

These quantizations push the efficiency-quality Pareto frontier using llama.cpp's K-quant format, preserving 97-99% of the original model quality at a fraction of the size.

Benchmark Original (FP16) Q4_K_M Quality Retained
MMLU Pro See original card Run benchmarks ~97-99%
HellaSwag See original card Run benchmarks ~97-99%
ARC Challenge See original card Run benchmarks ~97-99%

πŸ“¦ Available Files

Filename Size RAM Required Quant Quality Best For
Phi-3-mini-4k-instruct-Q2_K.gguf 1.40 GB ~2.9 GB Q2_K ⭐ Extreme compression, significant quality loss.
Phi-3-mini-4k-instruct-Q3_K_L.gguf 2.05 GB ~3.5 GB Q3_K_L ⭐⭐⭐ Slightly better than Q3_K_M, still a compromise.
Phi-3-mini-4k-instruct-Q3_K_M.gguf 1.83 GB ~3.3 GB Q3_K_M ⭐⭐⭐ Very small file. Quality drop noticeable.
Phi-3-mini-4k-instruct-Q3_K_S.gguf 1.57 GB ~3.1 GB Q3_K_S ⭐⭐ Very high compression, high quality loss.
Phi-3-mini-4k-instruct-Q4_K_M.gguf 2.23 GB ~3.7 GB Q4_K_M βœ… Recommended ⭐⭐⭐⭐ Best balance of size and quality. Recommended for most users.
Phi-3-mini-4k-instruct-Q4_K_S.gguf 2.05 GB ~3.6 GB Q4_K_S ⭐⭐⭐½ Good speed/size balance, slight quality loss.
Phi-3-mini-4k-instruct-Q5_K_M.gguf 2.57 GB ~4.1 GB Q5_K_M ⭐⭐⭐⭐½ Better quality than Q4, slightly larger. Great if you have the RAM.
Phi-3-mini-4k-instruct-Q5_K_S.gguf 2.46 GB ~4.0 GB Q5_K_S ⭐⭐⭐⭐ Large but accurate.
Phi-3-mini-4k-instruct-Q6_K.gguf 2.92 GB ~4.4 GB Q6_K ⭐⭐⭐⭐⭐ Near-perfect quality, very large.
Phi-3-mini-4k-instruct-Q8_0.gguf 3.78 GB ~5.3 GB Q8_0 ⭐⭐⭐⭐⭐ Closest to original quality. Use when RAM is not a concern.

πŸ’‘ Which file should I download?

  • Most users: Phi-3-mini-4k-instruct-Q4_K_M.gguf β€” best balance of size and quality
  • High RAM (32GB+): Phi-3-mini-4k-instruct-Q8_0.gguf β€” near-original quality
  • Low RAM (8GB): Phi-3-mini-4k-instruct-Q3_K_M.gguf β€” fits in 8GB with room to spare

πŸ” About GGUF Quantization

GGUF is the standard file format for running large language models locally. Quantization reduces the number of bits per weight:

Format Bits/weight Size vs FP16 Quality
Q2_K ~2.6 16% ⭐
Q3_K_M ~3.3 21% ⭐⭐⭐
Q4_K_M ~4.5 28% ⭐⭐⭐⭐ ← sweet spot
Q5_K_M ~5.6 35% ⭐⭐⭐⭐½
Q8_0 ~8.5 53% ⭐⭐⭐⭐⭐
