Quick takeaways
  • 1Output tokens usually cost 4–8× more than input — keeping replies short is the highest-leverage cost saver.
  • 2Anthropic prompt caching drops repeat-input cost by ~90%; OpenAI cached input drops it by ~90% on GPT-5.
  • 3DeepSeek off-peak hours (16:30–00:30 UTC) are 10× cheaper than peak — schedule batch jobs accordingly.
  • 4Gemini 2.5 Pro doubles its input price above 200K context — large-context calls cost roughly twice as much.

Claude.ai subscription vs API

Claude Pro ($20/mo) and Claude Max ($200/mo) include generous usage caps that are usually cheaper than the API up to a break-even point. Beyond that point, the API — or a third-party router like OpenRouter — is the right choice.

Claude Pro · $20/mo

Break-even: ~1.90M input + 0.95M output per month

Below this combined usage the Pro plan is cheaper; above it the API starts winning.

Claude Max · $200/mo

Break-even: ~19.0M input + 9.52M output per month

For sustained heavy usage, Max covers you up to roughly the API equivalent of $200/mo.

Sample reference: 1M input + 500K output tokens via the API costs $10.50 / month (at current Sonnet 4.5 rates).

How to bring the bill down

  1. 1Use a smaller model for routing / classification — Haiku 4.5 / GPT-5 nano cost roughly 5–10× less than the flagship.
  2. 2Cache repeat prefixes (system prompts, tool schemas) — Anthropic cached input drops the rate by ~90%.
  3. 3Set max_tokens explicitly — output is the expensive side; capping it prevents runaway replies.
  4. 4Batch non-urgent jobs into DeepSeek off-peak hours (16:30–00:30 UTC) for ~10× cheaper inference.
  5. 5Trim long context — Gemini 2.5 Pro doubles its input rate above 200K; chunk documents that don't need the rest.

Claude Sonnet 4.5 is $3 per 1M input tokens and $15 per 1M output tokens via the Anthropic API. With prompt caching, cached reads drop to $0.30 per 1M (90% off). The 5-minute cache write is $3.75 per 1M; the 1-hour cache write is $6 per 1M.
