For tasks with high accuracy requirements such as code completion, Q5 or Q8 quantization is generally more reliable; for tasks with high error tolerance such as summarization and casual chat, Q4 is often the most cost-effective starting point.

UnverifiedCompared to Q4 quantization, Q8 quantization retains higher precision closer to the original model quality, but consumes more VRAM.75% similarVerifiedQ4 quantization is considered the best balance between quality and size, and is the most cost-effective choice for most developers.74% similarUnverifiedIt is recommended to start with the Q4 quantized version before deciding, based on actual performance, whether to switch to a higher-precision version.71% similarUnverifiedRecommended quantization gradient choices: Q8 is nearly lossless but has the largest footprint, Q6/Q5 are the sweet spot between quality and size, Q4_K_M is the default download version for most users, and the Q2/IQ series is suitable for use when the model barely fits.71% similar
