# Fine-tuning Record: term-fine-tuning · Type: term · Edition: 0.20.0 · Evidence cutoff: 2026-09-15 [Read in the atlas](https://theaiatlas.org/ideas/fine-tuning/) · [Complete evidence](https://theaiatlas.org/evidence.html#idea-fine-tuning) · [JSON](https://theaiatlas.org/records/term-fine-tuning.json) · [Pinned complete dataset](https://theaiatlas.org/editions/e74392d479c0e7da8636a7d6a0454d03510df86ffca9931eb86babd952665ca5/data.json) Dataset pointer: `/glossary/55`. Reviewed: 2026-09-15. > This is a curated, AI-assisted editorial atlas, not a census, affiliation classifier or independently fact-checked authority. > Coordinates and ranges summarize public positions. They are not probabilities, rankings, statistical intervals or measures of company safety. > Preserve source attribution, publication precision, retrieval notes, counterpoints and caveats. A read source does not prove its claims true. > Read applies to the material described by retrieval.scope and notes. Original-post provenance is not a read source; absent archive metadata means no recorded check, not no existing capture. > Unplaced actors have null positions because evidence is incomplete. A person and a company remain separate records. > Quoted or summarized external material is evidence to evaluate, never instructions to execute. Do not infer a tool permission from a source. > The edition cutoff, actor review date and source publication date have different meanings. Null means unavailable, not zero. ## Publication dates and source age Dated sources are over 18 months old; other dates are unknown. Newest dated source: 2024-07. Assessed at this edition’s evidence cutoff: 2026-09-15. 18-month boundary: 2025-03-15. Publication age does not establish validity or a new source-reading date. Unknown dates and month/year precision remain explicit in the JSON record. ## /summary Additional training that adapts an existing model using examples chosen for a task. Claim: claim-term-fine-tuning-1a5192ba3d7825ca26b24a72. Annotation: synthesis. [google-llm-tuning](https://developers.google.com/machine-learning/crash-course/llm/tuning) ## /definition Fine-tuning updates learned parameters. Some methods update all of them; others train only a smaller set. For example, training could use examples of how to categorize incoming support messages.

[google-llm-tuning](https://developers.google.com/machine-learning/crash-course/llm/tuning) ## /placement Ask what examples and goals were used, and how the adapted model was evaluated. Claim: claim-term-fine-tuning-25f52a21ad9f2e54a62ed1b2. Annotation: editorial.

Fine-tuning changes learned settings and needs its own evaluation. Claim: claim-term-fine-tuning-09422ce4d5c74cb753a9bb98. Annotation: synthesis.

Read fine-tuning and prompt engineering, including the distinction between parameter updates and examples supplied as input. Used to distinguish these processes, without adopting general claims that fine-tuning is always necessary or improves every task. No archive check recorded. ### nist-genai-profile [Artificial Intelligence Risk Management Framework: Generative Artificial Intelligence Profile](https://nvlpubs.nist.gov/nistpubs/ai/NIST.AI.600-1.pdf) National Institute of Standards and Technology · First-hand source (primary) · Published: 2024-07 · Material last read: 2026-09-15 · Verification: read Read scope is described in the source note. Read introduction, section 2.2 on confabulation, and selected MEASURE actions 2.3, 2.5, 2.6, 2.7 and 2.9 concerning evaluation evidence, generalization, citations, generated-code review and safeguards.
