Models & Tools

GPT (Generative Pre-trained Transformer)

GPT is OpenAI's family of large language models — including GPT-4o and GPT-4 — that power ChatGPT and are widely used for text generation, analysis, coding, and business AI applications.

What Is GPT?

GPT (Generative Pre-trained Transformer) is OpenAI's series of large language models, with GPT-4o being the current flagship model. GPT models power ChatGPT and are accessed via API for business applications. The "generative" means it produces content, "pre-trained" means it learned from vast data before deployment, and "transformer" refers to the neural architecture.

How Do Businesses Use GPT Models?

GPT models are deployed for customer service, content generation, code development, data analysis, document processing, and as the reasoning engine in agentic AI systems. AffixedAI uses GPT-4o for consultation AI and business profile extraction, often alongside Claude for different tasks — selecting the best model for each specific use case.
