- Q8_0
These are quantized versions of the same model.
Quantization reduces the model’s size, making it easier to run on consumer hardware while maintaining much of its performance.
General Rule
| Quantization | Speed | Quality | RAM Usage |
|---|---|---|---|
| Q4 | Fast | Very Good | Low |
| Q5 | Balanced | Excellent | Moderate |
| Q6 | Slightly Slower | Excellent | Higher |
| Q8 | Slowest | Highest | Highest |
For most laptop users, Q4 or Q5 provides the best balance between speed and quality.
How Much RAM Do You Really Need?
Memory is often the biggest limitation when running local AI models.
Here’s a practical guideline:
| Laptop RAM | Recommended Model Size |
|---|---|
| 8 GB | Small models (3B–4B) |
| 16 GB | 7B models |
| 24 GB | 8B–12B models |
| 32 GB | Larger models with smoother multitasking |
| 64 GB+ | Professional experimentation |
Keep in mind that your operating system and other applications also consume memory, so avoid using all available RAM for the model alone.
CPU vs GPU: Which Matters More?
Many beginners assume a powerful graphics card is required.
In reality:
