## Cost Optimization

### Choose the Right Model

| Use Case              | Recommended   | Why                          |
| --------------------- | ------------- | ---------------------------- |
| Simple classification | GPT-3.5-turbo | Very fast and cost-effective |
| Complex reasoning     | GPT-4o        | Best quality/cost balance    |
| High volume           | Claude Haiku  | Very low cost per request    |
| Critical quality      | Claude Opus   | Worth the premium            |

### Optimize Prompts

* **Be concise** — Remove unnecessary instructions
* **Use snippets** — Avoid repeating common text
* **Set appropriate max\_tokens** — Don't request more tokens than needed

### Enable Caching

Caching returns instant responses for identical requests:

* No LLM call = faster response and lower costs
* Enable for endpoints with frequently repeated queries

## Trials and Free Tier

New accounts start with a free trial:

* Full access to platform features
* Trial period shown on your billing page
* Upgrade anytime to continue after trial ends

<Warning>
  When your trial expires, you'll need to select a plan to continue using the service.
</Warning>
