- Best for developers creating specialized chatbots, document analyzers, or custom AI tools.
- Requires technical expertise for training and optimization.

Boosting Performance with Quantization

For users with less powerful devices, quantization can enhance AI performance by reducing model size without a major drop in efficiency.

What is quantization? A process that compresses the AI model for better speed and efficiency.
Why use it? Ensures smoother performance on phones, tablets, and older laptops.
How to get it? Google provides pre-quantized versions, making it easy to implement.
