Which Quantization Should I Use?

A simple rule of thumb:

Quantization Quality Size Recommended for
BF16 ★★★★★ Very large Maximum precision
F16 ★★★★★ Large Maximum precision
Q8_0 ★★★★★ Large Near-original quality
Q6_K ★★★★★ Medium High quality
Q5_K_M ★★★★☆ Medium Quality / size balance
Q5_0 ★★★★☆ Medium General use
Q4_K_M ★★★★☆ Small Recommended default
Q4_0 ★★★☆☆ Smallest Maximum memory savings

Q4_K_M is the recommended starting point for most users who want a good balance between quality and memory usage.
