What is the Anthropic API best at?

Claude models are widely praised for coding, careful reasoning, and handling long documents reliably.

How is the Anthropic API priced?

Per input and output token, with rates depending on the model tier. Prompt caching and batch processing can cut costs substantially for repeated or high-volume workloads.

How does prompt caching save money?

With prompt caching you write a long stable prefix (system prompt, docs) once and reuse it across requests at a much lower per-token rate. Repeated calls with a shared prefix stop re-billing the full context, which cuts cost on long-conversation or RAG workloads.
