## Frequently Asked Questions

**Q: How much does custom AI development cost?**
A: It depends heavily on complexity: simple AI features cost far less than full AI agents or RAG systems. Compare the development cost with the SaaS cost over three years – with higher usage, your own solution is often more economical.

**Q: Can we use Claude/GPT in custom solutions?**
A: Yes, custom development often means integrating current AI models (such as Claude, GPT, or Gemini) into your workflows with custom logic, prompts, and data pipelines.

**Q: What about data privacy with custom AI?**
A: With custom AI, you control data flow completely. You can use EU-hosted API endpoints, or even self-host open-source models for maximum privacy.
