Fine-tuning
Extra training given to an already-trained model to make it better at a particular job, style or subject.
Distillation
Training a smaller, cheaper model to copy the behavior of a bigger one, so it runs faster at some loss of ability.
Parameters (weights)
The numbers inside a model that are adjusted during training and hold what it has learned. Big models have hundreds of billions or more.
Training run
One long job, often lasting weeks to months on thousands of chips, in which a model learns from its training data. Its size is usually measured in FLOP of compute.
Compute
Computing power: the chips, and the amount of calculation they do, used to train and run AI. It is often counted in FLOP.
FLOP (floating-point operation)
One basic arithmetic step on decimal numbers. The total FLOP used to train a model (e.g. 10^25) is a standard way to say how big a training run was.
