FAQ
What do I need to provide to get started?
I need a clear description of what your AI agent or chatbot should do, what data sources it will use (PDFs, URLs, databases, or APIs), and any specific integrations required. After you message me, I will ask the right questions to fully understand your requirements before we begin.
Can you integrate the AI agent into my existing app or website?
Yes. I can integrate the RAG chatbot or AI agent into your existing application, connect it to your current database, and build a FastAPI REST API endpoint your frontend can call directly. Just share your tech stack and I will confirm compatibility.
Which LLM do you use — GPT-4o, Claude, or open-source?
I primarily work with GPT-4o and Claude, but I can also use open-source models like Llama or Mistral depending on your requirements and budget. Open-source models are a good option if you need data privacy or want to avoid ongoing API costs.
Will I receive the full source code after delivery?
Yes. Every delivery includes the complete, well-commented source code so your team can maintain, extend, or modify the system independently. I also provide a brief documentation explaining how the system works.
What if my project is more complex than the packages listed?
No problem. Message me before ordering and describe your requirements. I handle custom scopes regularly — including multi-agent pipelines, complex RAG systems, and production deployments. I will send you a custom offer with the right timeline and price for your specific project.
