How is LLM API pricing calculated?

LLM APIs charge per token, priced per million tokens ($/1M). Input and output have separate rates — output is typically 3-5x more expensive. The total cost = (input tokens / 1M × input rate) + (output tokens / 1M × output rate).

What is prompt caching and how does it save money?

Prompt caching lets you reuse previously processed input tokens at a reduced rate (typically 90% cheaper). For Anthropic, cached reads cost $0.30/1M vs $3/1M standard for Claude Sonnet. This is ideal for system prompts or repeated context.

Which LLM is the cheapest for production use?

It depends on your quality requirements. For general tasks: DeepSeek V3 ($0.27/$1.10 per 1M) and Gemini 2.0 Flash Lite ($0.075/$0.30) are extremely cost-effective. For high-quality outputs: Claude Haiku 4.5 ($1/$5) and GPT-4.1 mini ($0.40/$1.60) offer excellent quality-to-cost ratios.
