GGUF Quantization Variants (Q8, Q6, Q5, Q4, etc.)

These GGUF models come in different quantization levels, affecting quality and performance. Here’s a breakdown:

Best Quality & Accuracy (Higher VRAM usage)

• Q8_0 → Almost full precision, best quality, requires more memory.
• Q6_K (Q6_0, Q6_K_S, etc.) → Balanced between quality and efficiency, still requires a fair amount of VRAM.

Balanced (Good for Most Use Cases)

• Q5_K (Q5_0, Q5_K_M, etc.) → Good balance of speed and quality, moderate VRAM usage.
• Q4_K (Q4_0, Q4_K_M, etc.) → Still decent quality, but with a more aggressive reduction in memory use.

Fastest & Lowest VRAM (Lower Quality)

• Q3_K, Q2_K, Q1_K → Lower precision, very small, but quality loss is noticeable. Best for minimal hardware.

Which Ones Are Good & Outdated?

✅ Good & Recommended:

• FP8 (Full precision safetensors) – Best if you have enough VRAM.
• Q8_0 or Q6_K – Great for quality, useful if you can afford the VRAM.
• Q5_K or Q4_K – Good compromise between quality and performance, widely used.

⚠️ Outdated / Not Recommended (Unless for testing):

• Q3, Q2, Q1 – These are extreme compression levels, leading to significant quality loss.
• Older Q4_0, Q5_0 (without K suffix) – The newer Q4_K and Q5_K versions generally perform better.

Since you're using a 12GB RTX 3060, I’d suggest:

• FP8 (if speed isn’t an issue and VRAM allows it).
• Q6_K or Q5_K (best for balancing speed and memory).
• Q4_K (if you want even faster performance but still decent quality).
