An analysis of the three main artificial intelligence models and their applications
(Input/Output)
The simplest models in their operation. They receive an input and directly produce an output without a visible intermediate step.
Question → Direct Answer
Prediction of the most probable words based on the provided input, without explicit intermediate reasoning.
(Chain of thought)
Models that add an intermediate step of reflection between input and output, allowing for more elaborate reasoning.
Question → Reasoning → Answer
The AI analyzes the request, defines reasoning steps, and then produces an answer based on this process.
(Agentic COT)
The most advanced models, capable not only of reasoning but also of using external tools and executing actions autonomously.
Question → Reasoning → Tool Use → Answer
The AI thinks, activates, and uses specific tools autonomously to accomplish complex tasks.
