FAQ
What is an AI Agent?
An AI Agent is an intelligent program that can perform tasks like answering questions, retrieving data, or automating workflows using AI models. It can be powered by cloud models like OpenAI GPT or local open-source LLMs for privacy.
What is the difference between using OpenAI API and a local LLM?
OpenAI API is cloud-based, fast, and requires an API key, but your data is processed on OpenAI’s servers. Local LLM (like LLaMA, Mistral, Vicuna) runs on your own machine or server — ensuring privacy and no API costs.
Can you deploy my AI Agent online?
Yes ✅ — I can integrate your AI Agent with FastAPI and deploy it to your server or cloud platform so it’s accessible via a web app or API endpoint.
What do I need to get started?
Just share your requirements, preferred AI model (OpenAI or local), and any specific tasks your AI Agent should perform. I’ll guide you through installation and setup.
What is RAG (Retrieval-Augmented Generation), and how can it benefit my business?
RAG combines retrieval-based search with generative AI to provide highly accurate, real-time responses. It improves chatbot accuracy, enhances customer support, and allows AI to generate precise answers based on your company’s data.
