Lesson & Term of the Day

Today's lesson

Why memory matters for AI accelerators and HBM supply

How high-bandwidth memory affects model fit, GPU value, and accelerator availability. Why it matters today: Today's lesson connects the Power & Data Centers track to the compute market readers are watching.

Term of the Day

Post-training

Post-training includes the steps used to improve or align a model after pretraining. This can include fine-tuning, reinforcement learning, preference training, evaluations, and safety work. It usually requires less compute than initial pretraining, but it can still be material.
