Why Look for Claude API Alternatives?
Anthropic's official Claude API pricing is steep:
| Model | Official Input | Official Output |
|---|---|---|
| Claude Opus 4.7 | $5/M tokens | $25/M tokens |
| Claude Sonnet 5 | $2/M tokens | $10/M tokens |
| Claude Sonnet 4.6 | $3/M tokens | $15/M tokens |
| Claude Haiku 4.5 | $1/M tokens | $5/M tokens |
For developers and startups, these costs add up quickly. A typical Claude Code session can burn through $5-10 per day. Here are the best alternatives.

5. Direct Anthropic API with Prompt Caching
