Model Optimization for Deployment
Explore key techniques to make our generative AI models more practical for real-world deployment.
We'll cover the following...
We’ve got a massive language model, like a star athlete who dominates on a wide track. But what happens when we ask that athlete to perform in a cramped phone booth or on a smaller field? That’s the real-world challenge:
Limited hardware on phones, edge devices, or small servers.
Low latency needs for real-time tasks like chatbots or translation.
High costs when running large models in the cloud.
This is where model optimization comes in. The goal is to shrink and speed up models so they fit these constraints while preserving as much of their power as possible. Just as an athlete adapts to different arenas without losing their edge, optimized models deliver high performance with lower latency, memory use, and cost.
Key techniques include knowledge distillation, quantization, pruning, and sparsity, each making the model leaner from a different angle.
What is knowledge distillation?
Knowledge distillation involves transferring knowledge from a large, powerful model (the teacher) to a smaller, faster one (the student). Instead of training the student only on hard labels (the correct answers), it also learns from the teacher’s soft probabilities: the nuanced patterns in the teacher’s predictions.
For example, the teacher might say, “This image is 90% likely a cat, 8% likely a fox, and 2% likely a dog.” The student uses this richer signal to understand subtle relationships and generalize better. The result is a lightweight model that runs efficiently while retaining much of the teacher’s accuracy.
These soft probabilities are valuable because they reveal more than just the right answer—they show the teacher’s reasoning. For example, the teacher might say an image is 80% ...
