Tips and Notes

• Prompt Caching: Claude models natively support prompt caching, which can reduce input token costs by up to 90% and latency for repeated prompts and repository context.
• Context Window: Claude models have large context windows (200,000 tokens), allowing you to include a significant amount of code and context in your prompts.
• Pricing: Refer to the Anthropic Pricing page for the latest pricing information.
• Rate Limits: Anthropic has strict rate limits based on usage tiers. If you're repeatedly hitting rate limits, consider contacting Anthropic sales or accessing Claude through a different provider like OpenRouter or Requesty.
