5 Ways to Cut Claude API Costs
1. Use the Right Model
Don't use Opus for simple tasks. Haiku costs 25× less than Opus for input tokens and handles classification, extraction, and simple Q&A perfectly well.
| Model | Anthropic retail input | Anthropic retail output | Best For |
|---|---|---|---|
| Haiku 4.5 | $1/1M | $5/1M | Simple tasks, classification |
| Sonnet 4.6 | $3/1M | $15/1M | General coding, analysis |
| Opus 4.7 | $5/1M | $25/1M | Complex reasoning, architecture |
At ClaudeStore you access all models via your credit balance — $45 covers $500 of usage at Anthropic's retail rates. Cache write = 1.25× input, cache read = 0.10× input.
2. Enable Prompt Caching
If you send the same system prompt repeatedly, enable prompt caching. Cached tokens cost 90% less than fresh input tokens. This is especially impactful for IDE integrations where system prompts are constant.
3. Optimize Prompt Length
Shorter prompts = lower costs. Remove unnecessary context, examples, and instructions. Use structured formats (JSON, lists) instead of verbose natural language when possible.
4. Set Max Tokens
Always set max_tokens to limit response length. Without it, Claude may generate unnecessarily long responses, wasting output tokens (which cost 5× more than input).
5. Use Per-Key Limits
ClaudeStore lets you set credit limits per API key. This prevents runaway costs from bugs or misconfigured scripts. Set a daily or total limit per key from your dashboard.
