FAQ
What AI models do you support?
I work with OpenAI GPT-4, Claude, Gemini, and open-source models like Llama and Qwen. I can recommend the best model for your budget and use case.
Can you build a RAG system with my own documents?
Yes. I can build a knowledge base Q&A system using your PDF, Word, or web content. The system uses vector databases like ChromaDB or Pinecone for accurate retrieval.
Do you deploy the AI agent for me?
Yes. The Premium package includes full deployment with Docker. I can deploy to your server, AWS, or any cloud platform.
Can the AI agent connect to my existing APIs or databases?
Absolutely. I specialize in building agents with custom tool calling that can interact with any REST API, database, or third-party service.
Which AI models do you support?
I work with OpenAI , Anthropic Claude, Google Gemin
Can the chatbot learn from my documents?
Yes! Using RAG (Retrieval-Augmented Generation), I can build a system that ingests your PDFs, websites, databases, or any documents and answers questions based on YOUR data accurately.
Will I need to pay for AI API costs?
Yes, the AI model API costs (e.g., OpenAI) are separate from my service fee. However, I can also set up local/open-source models if you want to avoid ongoing API costs.
Can you integrate the AI with my existing app?
Absolutely! I can provide the AI agent as a REST API that integrates with any existing system — web apps, mobile apps, Slack, Discord, WhatsApp, and more.
