Why token costs vary
Not all tokens are created equal.
Input vs Output
Almost every AI provider charges more for output tokens (completions) than input tokens (prompts). This is because generating a token is computationally more expensive than reading one.
Context Caching
Providers like Anthropic and Google now offer prompt caching, which significantly reduces the cost of repeating large system prompts across multiple requests.
