GPTs

● CoreGPTs

OpenAI's way of packaging a prompt, instructions, knowledge files, and tool integrations into a shareable chatbot, without code.

Think of it like

A template for ChatGPT—set the personality, upload docs, link to your tools, share a link.

Example

Create a GPT called 'Tax Advisor' with IRS docs and a calculator tool. Share a link; anyone can chat with it. No coding required.

How it actually works

GPTs are ChatGPT + configuration + files + tools. Under the hood, they're still just LLM calls, but the packaging makes them accessible to non-engineers. You can publish them, sell them, or keep them private. Limited: no custom training, no fine-tuning, constrained to OpenAI's ecosystem.

For product teams

Democratizes agent deployment; enables non-technical users to build AI assistants.

For engineers

Configuration-based; no code; limited to ChatGPT capabilities.
