Token Optimization

Practice of reducing the number of tokens sent to and received from an LLM without losing task quality. Includes prompt caching, message pruning, context window management, and structured output.

Stories on this topic · 4

Overview

Token optimization refers to the strategic techniques used to minimize the number of tokens consumed during interactions with large language models without compromising task output. It sits at the intersection of cost management and architectural efficiency, involving methods like prompt caching, context pruning, and enforcing structured output formats to reduce extraneous data.

Implement these strategies when working with large codebases or long-running agentic loops where token costs can escalate rapidly. The main trade-off is the balance between aggressive pruning and the model's ability to retain sufficient semantic context. Being overly restrictive with the input data may lead the model to lose track of global project structure or relevant code dependencies.

Overview based on established industry knowledge; specific figures are published only after source verification.

FAQ

Is prompt caching always effective for reducing costs?+

It is highly effective for static content that remains unchanged across multiple requests, but less useful for highly dynamic inputs.

Does structured output hurt model performance?+

Not necessarily; structured output often improves reliability and parsing, though it may consume extra tokens to enforce the format.
