## 📘 FAQ

**Q: Which AI providers are supported?**
A: Currently OpenAI (GPT models) and Anthropic (Claude models) are supported, with more providers planned.

**Q: How can I reduce API costs?**
A: Use GPT-3.5-Turbo or Claude-3-Sonnet for most queries, implement caching, and optimize token usage.

**Q: Are there limitations on the number of requests?**
A: Depends on your API provider's plan. We recommend monitoring usage and implementing request throttling via `request_interval` configuration.

**Q: Can I use custom models?**
A: Yes, you can configure custom endpoints and use any compatible model by specifying it in the configuration.

**Q: How do I switch between different AI providers?**
A: Simply change the model parameter in your configuration or service calls to use the desired provider's model.

**Q: How can I reduce API costs?**
A: Use GPT-3.5-Turbo for most queries, implement caching, and optimize token usage.

**Q: Is my data secure?**
A: Yes, your data is secure. The system operates entirely on your local machine, keeping your data under your control. API keys are stored securely and all external communications use encrypted connections.

**Q: How do context messages work?**
A: Context messages allow the AI to remember and reference previous conversation history. By default, 5 previous messages are included, but you can customize this from 1 to 20 messages to control the conversation depth and token usage.

**Q: Where is conversation history stored?**  
A: History is stored in files under the `.storage/ha_text_ai_history/` directory, with automatic rotation and size management.

**Q: Can I access old conversation history?**  
A: Yes, archived history files are stored with timestamps and can be accessed manually if needed.

**Q: How much history is kept?**  
A: By default, up to 100 conversations are stored, but this can be configured. Files are automatically rotated when they reach 1MB.
