Domain tuning adjusts a pretrained model toward specialized terminology and tasks. Its primary purpose is specialist domain language behavior, not better instruction-following performance.

Stable format adaptation can be learned from examples after evaluation. It solves persistent custom structured-response behavior, not better instruction-following performance.

A one-off tone adjustment does not warrant model training. That addresses transient single-message stylistic change, not better instruction-following performance.

RLHF uses human preference signals to guide model behavior. It would support reward-aligned response behavior, not comparative human output feedback.

Live human review is governance during use, not simply model training. That is useful for approval of consequential generated advice, not comparative human output feedback.

Verified feedback can inform future adaptation after proper curation. Its primary purpose is improving future model behavior from corrected cases, not comparative human output feedback.

Near-duplicate leakage inflates performance scores. That addresses avoiding repeated-case test contamination, not unbiased fine-tune evaluation.

Evaluation coverage must match supported use cases. It would support multilingual fine-tune validation, not unbiased fine-tune evaluation.

Benchmark overfitting makes reported final quality overly optimistic. Its primary purpose is protected final benchmark independence, not unbiased fine-tune evaluation.

Persistent adaptation can justify tuning costs when prompt steering falls short. It solves repeated specialized terminology errors, not avoiding unnecessary tuning expense.

Full pretraining carries much larger costs than most task adaptation. That addresses feasibility of custom foundation-model training, not avoiding unnecessary tuning expense.

Distillation economics depend on downstream volume and performance loss. It would support payback of lower-cost inference model, not avoiding unnecessary tuning expense.

Adapter tuning presupposes a pretrained base model. Its primary purpose is entirely new model initial learning, not adaptation with limited trainable parameters.

Adapters can express task variations without replacing the underlying base weights. That addresses multiple task variants from one base, not adaptation with limited trainable parameters.

Knowledge refresh is often better served through retrieved context. It would support changing factual source content, not adaptation with limited trainable parameters.

Versioned deployment provides a recovery path from regressions. That is useful for regression recovery after tuning, not traceable tuned-model provenance.

Limited exposure detects issues before full traffic migration. Its primary purpose is low-risk tuned-model introduction, not traceable tuned-model provenance.

Training compliance failures require governance response beyond performance scores. It solves training-data privacy incident response, not traceable tuned-model provenance.

Current facts are better refreshed through source retrieval than frequent weight updates. That is useful for current newly published policy facts, not consistent domain-specific output format.

In-context demonstrations need no training job. Its primary purpose is immediate few-example guidance, not consistent domain-specific output format.

Student models can imitate teacher behavior with reduced resource requirements. It solves compact student for constrained deployment, not consistent domain-specific output format.

Training input legality is independent of model output quality. It would support copyright-compliant model training inputs, not representative visual conditions.

Privacy minimization reduces exposure and memorization of unneeded details. That is useful for reduced personal data in training, not representative visual conditions.

Noisy synthetic labels can amplify errors rather than improve learning. Its primary purpose is trustworthy synthetic demonstration quality, not representative visual conditions.

Distillation transfers useful learned behavior to a potentially cheaper student. It solves compressed model capability transfer, not specialized pretrained-model behavior.

Pretraining learns broad representations before downstream task specialization. That addresses creation of general base model weights, not specialized pretrained-model behavior.

Continued pretraining extends base representations with more broadly distributed domain data. That is useful for expanded domain-language knowledge, not specialized pretrained-model behavior.

Prompt examples guide one call without weight updates. It solves temporary task formatting, not fresh policy knowledge grounding.

Student models may reduce serving cost if retained quality is adequate. That addresses lower-cost serving through model compression, not fresh policy knowledge grounding.

Repeated behavior changes can justify weights adaptation. It would support persistent response-style learning, not fresh policy knowledge grounding.

Training input rights and privacy requirements constrain allowed source materials. That is useful for lawful approved model-training sources, not multilingual training coverage.

Label consistency improves supervised learning quality. It solves reliable training labels for safety data, not multilingual training coverage.

Data hygiene and privacy controls reduce memorization and unnecessary exposure. That addresses privacy-preserving training curation, not multilingual training coverage.
