Custom AI Agent Development FAQ

  • What is AI agent development, and how does it work?

    AI agent development involves designing, training, and deploying autonomous systems that can interact with users, process information, and make decisions based on real-time data. Unlike traditional software that follows pre-programmed rules, AI agents use machine learning models, natural language processing (NLP), and knowledge retrieval systems to perform complex tasks.

    At Deviniti, we specialize in custom AI agent development, creating domain-specific solutions that integrate with enterprise workflows, ensuring seamless automation and intelligent decision-making. Our AI agents are built to adapt, learn, and improve over time—making them far more advanced than standard automation tools.

  • What are the key benefits of using a custom AI agent instead of a pre-built AI tool?

    A custom AI agent is designed to fit a company’s specific needs, while pre-built AI tools offer limited flexibility. Here’s why custom AI agents deliver better value:

    Tailored to business processes – Unlike ready-made AI tools, custom AI agents align with unique workflows, policies, and industry standards.
    No functionality restrictions – Pre-built AI tools limit users to predefined capabilities, whereas custom agents can be expanded and fine-tuned over time.
    Seamless integration – Custom AI agents connect with existing enterprise systems, ensuring real-time data synchronization and operational efficiency.
    Data privacy and security – A self-hosted or custom-built AI agent gives full control over data protection and compliance.

    At Deviniti, we develop custom AI agents that integrate seamlessly with business environments, ensuring that companies get the full benefits of AI—without the constraints of generic tools.

  • How does an AI agent differ from a chatbot?

    While chatbots and AI agents both use AI, their capabilities are vastly different:

    • Chatbots follow predefined scripts and handle simple interactions, such as answering FAQs. They don’t adapt dynamically to new information.
    • AI agents are autonomous systems that understand complex queries, make decisions, and execute tasks based on real-time data. They can learn, improve, and adapt over time.

    For example, a chatbot can provide a pre-set response to a customer inquiry, while an AI agent can analyze customer data, pull insights from internal databases, and generate a personalized response based on the latest available information.

  • Is ChatGPT an AI agent, or does it function differently?

    ChatGPT is a large language model (LLM) designed for generating text-based responses, but it is not a fully autonomous AI agent.

    🔹 ChatGPT is primarily a conversational AI that responds based on pattern recognition, without direct interaction with external business systems.
    🔹 AI agents, on the other hand, can execute tasks, retrieve and process real-time data, and integrate with enterprise workflows.

    At Deviniti, we develop custom AI agents that go beyond simple conversations, integrating them with business processes to automate decision-making, handle data retrieval, and execute domain-specific tasks.

  • What are the five types of AI agents, and how are they used in business?

    AI agents are categorized based on their level of autonomy and decision-making ability:

    1. Simple Reflex Agents – Act only based on current conditions (e.g., rule-based customer support bots).
    2. Model-Based Agents – Maintain an internal model of the world to improve decision-making (e.g., AI agents analyzing customer interactions).
    3. Goal-Based Agents – Evaluate multiple possible actions to choose the most effective one (e.g., sales AI recommending personalized offers).
    4. Utility-Based Agents – Optimize for maximum benefit, often used in risk analysis and fraud detection.
    5. Learning Agents – Continuously learn from data, user feedback, and past actions, improving performance over time (e.g., AI-driven knowledge management systems).

    At Deviniti, we build domain-specific AI agents tailored to business needs, combining automation, decision-making, and self-learning capabilities.

  • How to build an AI agent for domain-specific tasks?

    Building an AI agent involves several key steps:

    4. System integration – Connecting the AI agent with internal databases, CRMs, and APIs.
    5. Testing & iteration – Running pilots, refining outputs, and improving accuracy.

    At Deviniti, we specialize in building custom AI agents optimized for industry-specific challenges, ensuring they integrate smoothly into business operations.

  • How do you train an AI agent to perform specialized functions?

    AI agents are trained through:

    Supervised learning – Using labeled data to teach the AI how to respond correctly.
    Fine-tuning – Adapting a pre-trained AI model (such as GPT-4, Llama, or Mistral) to industry-specific terminology and processes.
    Reinforcement learning – Allowing the AI agent to learn from feedback and refine its decision-making.
    RAG (Retrieval-Augmented Generation) – Enhancing AI accuracy by integrating external knowledge sources for real-time updates.

    At Deviniti, we ensure AI agents are continuously refined and improved, using real business data and real-world testing to optimize their performance.
