TL;DR. Steering model outputs precisely along specific dimensions like style, length, tone, or factuality.

Technical Definition

Steering model outputs precisely along specific dimensions like style, length, tone, or factuality.

How it works

Achieved through structured prompting, control tokens, classifier-guided decoding, constrained decoding (grammar/JSON), and fine-tuning on attribute-labeled data. Increasingly important for production apps that need predictable, brand-safe outputs.

Related Concepts

• Fine-Tuning — Adapting a pre-trained model to a specific task by continuing training on a smaller, task-specific dataset.
• Prompt Engineering — The art of crafting effective input instructions to guide LLM behavior without changing model weights.
• Guardrails — Runtime checks that constrain model inputs and outputs to stay within safe, useful bounds.
