'Fine-tune' in AI means taking an already-trained model and giving it more training on specific data to specialise it for a task. 'I fine-tuned a model on customer service' = 'I trained the existing model further on customer-service data'. Standard AI vocabulary. If your teen uses it, they are engaging with AI at a technical level. Useful for school, university and future work in tech.

Verb form of fine-tuning. "We fine-tuned Llama on our support tickets" = we continued training the base model on our specific data. Increasingly replaced by RAG + better prompts for most use cases — fine-tuning now mostly lives in enterprise compliance and voice-matching work.
"Fine-tuned a small model for cheap inference."

'Fine-tune' in AI means taking an already-trained model and giving it more training on specific data to specialise it for a task.

For ESL learners
'Fine-tune' is AI/ML terminology meaning to take a pre-trained model and apply further training on a more specific dataset to adapt it to a particular task or domain. Distinct from training a model from scratch. Register: technical, AI/ML industry, semi-formal. Acceptable in academic and technical writing as-is. A common learner mistake is to confuse fine-tuning with prompting (giving a model instructions at inference time); fine-tuning modifies the model's weights, prompting does not.

Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.

- fine-tuning75%
Continuing to train a foundation model on a smaller, specialized dataset so it specializes in your task. Increasingly replaced by RAG + prompt engineering for most use cases.
- few-shot59%
Giving an LLM a handful of input/output examples in the prompt before asking it to handle a new case. A cheap alternative to fine-tuning. "Few-shot examples in the prompt boosted accuracy by 15%." For complex tasks, three good examples often outperform a 200-word system prompt.
- tune58%
(informal) The act of tuning or maintenance.
- prompt engineering56%
The craft of writing inputs to LLMs to reliably produce the output you want. Includes role-setting, few-shot examples, chain-of-thought, and careful phrasing.
