Common questions about this comparison answered.

Frequently Asked Questions

(01)How much does custom AI development cost?
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.
(02)Can we use Claude/GPT in custom solutions?
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.
(03)What about data privacy with custom AI?
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.
