An application uses Claude 3.5 Sonnet and implements Prompt Caching for a 10,000-token system prompt. The application processes 1,000 requests per hour. If the cache is refreshed every request and never expires, how does the billing for the input tokens change after the very first request?

A developer is using the Claude Messages API to process a 50,000-token document for a summarization task. The summarization prompt and instructions add another 1,000 tokens. The developer wants to minimize output token costs while ensuring a comprehensive summary. Which strategy is most effective?

A team is estimating costs for a new feature that will send 1 million requests per month. Each request has a 2,000-token input and generates a 500-token output. The team wants to reduce the output token cost, which dominates the bill. Which strategy is MOST effective for reducing output token costs?

A developer is building a real-time translation service that must respond within 1 second for short phrases. The service will handle thousands of requests per hour. Quality is important, but latency and cost are critical. Which Claude model is the most appropriate?
