Everything You Need to Know About OpenAI

If you want to understand OpenAI, focus on these essential products and concepts.

1. GPT Models

OpenAI's core AI models.

The current GPT-5.6 family includes:

• GPT-5.6 Sol → flagship for complex reasoning and professional work

• GPT-5.6 Terra → balance of capability and cost

• GPT-5.6 Luna → fast, cost-efficient workloads

For developers, GPT models are used for reasoning, coding, vision, tool use and building AI applications.

2. ChatGPT

OpenAI's main consumer and professional AI application.

You can use it for:

• Writing

• Research

• Coding

• Data analysis

• File analysis

• Image generation

• Voice

• Problem-solving

• Creating documents and other deliverables

ChatGPT = AI application built around OpenAI models.

3. Codex

OpenAI's AI coding agent.

It can help developers:

• Write code

• Review code

• Debug

• Refactor

• Work across repositories

• Complete software-engineering tasks

GPT → thinks about the problem / Codex → helps actually build the software

4. OpenAI API

The API lets developers put OpenAI models inside their own applications.

Basic concept: Your application → OpenAI API → GPT model → Response

You can build:

• Chatbots

• AI assistants

• Data-analysis tools

• AI agents

• Coding tools

• Automation workflows

OpenAI's current API supports its latest frontier models and tools such as web search, file search and computer use.

5. Agents

Instead of simply answering a question, an AI agent can perform multi-step work using tools.

For example: Goal → Research → Analyze → Use tools → Produce result

This is one of the most important directions in modern AI development.

6. GPT Image

OpenAI's image-generation and editing models allow you to:

• Generate images

• Edit images

• Transform images

• Understand visual inputs

• Create visual content

GPT Image 2 is currently listed by OpenAI as its latest image-generation model.

7. GPT-Live

OpenAI's newer voice-model family powers natural voice interaction in ChatGPT.

The goal is more natural real-time conversation, including interruptions and back-and-forth interaction.

8. OpenAI Developer Platform

The developer ecosystem includes:

• API

• SDKs

• Codex

• Agent development

• Tools

• Model APIs

• Developer documentation


9. OpenAI Safety & Research

OpenAI isn't only a product company. It also develops research around:

• AI reasoning

• Agents

• AI safety

• Cybersecurity

• Scientific research

• Model evaluations

• Alignment

GPT-5.6, for example, includes capabilities aimed at complex professional work, coding, science and cybersecurity.

10. Sora — Important Update

Sora was OpenAI's video-generation product, but the Sora product was discontinued on April 26, 2026. So it should no longer be treated as a current OpenAI product when learning the ecosystem.

The OpenAI Ecosystem

• Everyday users: ChatGPT → GPT models → Voice → Images

• Developers: GPT models → API → SDKs → Agents → Codex

• Data Analysts: ChatGPT → File/Data Analysis → GPT → Python/SQL → Automation

• Software Developers: GPT → Codex → API → Agents

• Businesses: ChatGPT → API → Agents → Enterprise workflows
