## AI overview

This guide explains token-budget-aware LLM reasoning, a technique for matching a model's reasoning-token budget to problem complexity. It covers the cost of reasoning and output tokens, prompt-level methods such as chain-of-thought and Chain of Draft, and architectural approaches including caching, routing, and memory.

## Source excerpt

Reasoning models think before they answer, and those reasoning tokens are usually part of what you pay for. They're billed as output tokens, the expensive kind, and a single request can generate a few hundred of them depending on the problem. If your ...
