Anthropic told you how to make Claude cheaper
without ever touching output quality.
The four request-level optimizations from Anthropic's own docs that cut your Claude API bill without swapping to a weaker model.
What's inside
- Prompt caching that kills repeated context costs
- The token math behind batching requests
- Output length controls that beat model swaps
- Zero quality tradeoff, straight from Anthropic
Cut Your Claude API Bill Without Cutting Quality

Why the smaller-model move backfires
Most developers hit a big bill and immediately downgrade to a cheaper model
Output quality drops, you re-run prompts, and the cost you 'saved' comes right back
The real lever was never the model — it's how you structure the request before it reaches Claude
Anthropic documented all of this, and almost nobody applies it
Optimization 1 — Prompt Caching
Identify the static context you send on every single call
Mark it so Claude caches it instead of re-processing it each time
Cached input tokens are billed at a fraction of the normal rate
The savings compound the more repetitive your context is...
