FINE-TUNING GUIDE#

Fine-Tuning Hub

Plan, train, evaluate, and operate model adaptations with explicit trade-offs and safeguards.

What fine-tuning changes#

Fine-tuning updates some or all of a pretrained model’s parameters using task examples or preference feedback. It can improve a measured behavior, such as output structure, tone, or task accuracy, but it does not automatically add fresh knowledge, eliminate hallucinations, or make a model safe.

Good reasons to test it#

  • • A stable, repeated behavior resists prompt-only fixes

  • • You have representative examples and a trustworthy evaluation set

  • • Shorter prompts or a smaller model may improve serving economics

  • • The chosen checkpoint and artifacts can be deployed and governed

Reasons to use another approach#

  • • Use retrieval or tools for changing or attributable knowledge

  • • Improve prompts when the desired behavior fits clear instructions

  • • Fix the product or data pipeline when the model lacks required context

  • • Delay training when data rights, quality, or evaluation are unresolved

A release-oriented workflow#

  • 1 Write the product goal, acceptance rubric, and failure budget.

  • 2 Create a sealed holdout from production-shaped success, failure, and safety cases.

  • 3 Measure prompt-only, few-shot, retrieval, and tool-use baselines.

  • 4 Select a licensed base model and the smallest practical adaptation method.

  • 5 Run a short, reproducible pilot and inspect learning curves and sample outputs.

  • 6 Compare quality, regressions, latency, throughput, and total serving cost.

  • 7 Canary the winning candidate with monitoring and a tested rollback path.
