Let's Review Conversational AI
A conversational bot (AI) is built by training or integrating a large language model, wrapping it with conversation logic, memory, and retrieval tools, then deploying it through APIs and user interfaces using cloud infrastructure. e.g. User input → Language understanding → Reasoning → Text generation → Response in which the bot uses RAG (Retrieval-Augmented Generation), for accuracy and real-time knowledge. Examples: chatbots, virtual assistants, customer support bots.
Conversational AI models like Generative AI, they’re not the same, but they’re closely related.
Modern Conversational bot (AI) is strong at reasoning, explanation, creativity, and general-purpose assistance.
They Optimized for real-time data and conversational tone that can create new content: such as text, images, music, code, videos, etc.
Examples: ChatGPT, Grok and Gemini perform tasks of image generators, music generators Also focused on efficiency, technical reasoning, and cost-effective large-scale modeling.
Modelling or Model is known to be (The Brain) where the AI generates responses.
- Trained on massive text datasets
- Learns grammar, facts, reasoning patterns
- Predicts the next token (word piece)
Common Model Types
- Rule-based models (simple, scripted)
- Machine Learning models
- Large Language Models (LLMs) like GPT-style models
Training & Fine-Tuning
- Pre-training: Learning general language (Trained on books, articles, code, conversations, Uses self-supervised learning)
- Fine-tuning: Specializing for tasks (support, sales, education). Optimized for conversation and safety.
- (RLHF - Reinforcement Learning from Human Feedback): Improves quality and safety
Backend & APIs OR Development Tools Role
This connects the AI to applications
- Python / JavaScript Core programming
- LangChain Connect LLMs to tools, memory, data
- LlamaIndex Document-based chat (RAG)
