Supervised fine-tuning (SFT)

Edit or adapt a modelFine-tuningReference

Instruction / domain tuning: keep training the model on curated input→output pairs to teach a task or style.

Objective
Edit or adapt a model
Targets
Weights
Format
Next-token training on curated data
Granularity
Full-weight or adapter
Lifecycle
QAT / QAD · needs gradients
Calibration
Full corpus
Compression
None — reshapes behavior, not size
Quality
Specializes behavior; risks catastrophic forgetting if over-tuned
Hardware
Training run — GPU-hours; full-weight needs the model in memory twice
