FAQ
What do you need from me to get started?
I need your use case, workflow steps, tools/APIs you want to connect, sample data if available, and your preferred deployment option. If you are unsure, message me and I will help define the scope.
What LLM will be used and who pays for API costs?
I can use OpenAI, Mistral, Anthropic, Gemini, or local models through Ollama depending on your needs. API costs are paid by the buyer using their own account/key unless agreed otherwise.
Can you integrate the AI agent into my existing application?
Yes. I can integrate it with your app using FastAPI endpoints, webhooks, databases, or third-party APIs. I can also provide a simple chat UI if needed.
Will the AI agent have memory?
Yes, if required. I can add short-term conversation memory, long-term memory, user-specific context, or database-backed memory depending on the workflow.
Can this handle multiple agents or complex workflows?
Yes. I can build LangGraph-based workflows with routing, tool calling, supervisor logic, and multiple specialized agents when the use case requires it.
What technologies do you use?
Python, FastAPI, LangGraph, LangChain, OpenAI, Mistral, Ollama/local LLMs, vector databases, SQL databases, APIs, webhooks, and Docker.
Do you deploy the system to production?
Yes. I can help deploy on a VPS, cloud server, Docker setup, or your preferred hosting platform. Production deployment scope depends on the package.
What if my requirements change mid-project?
Small changes can usually be handled during development. Bigger changes, new integrations, or extra workflows may require an additional order or custom offer.
Is this only a chatbot?
No. A chatbot only replies to messages. An AI agent can use tools, call APIs, process data, make decisions, and complete multi-step tasks based on your workflow.
