Yes, 100% free. No sign-up, no credit card. All 23 modules, 43 lessons, 9 terminal labs, and 99 quizzes are immediately accessible. Progress saves locally in your browser.

Question 4

What topics does the OpenAI Academy cover?

Accepted Answer

The course covers ChatGPT essentials, Custom GPT creation, API integration, the Responses API, the Agents SDK, and frontier reasoning models.

Question 5

Do I need programming experience?

Accepted Answer

No prerequisites required for the first modules (ChatGPT and Custom GPTs). The later modules on the API and Agents SDK require basic programming knowledge, particularly in JavaScript or Python.

Question 6

What is the Responses API?

Accepted Answer

The Responses API is the unified endpoint introduced in 2025/2026 that replaces both Chat Completions and the Assistants API, offering built-in tools like web search and native conversational memory.

Question 7

What is the difference between GPT-5.6 Luna, Terra, and Sol?

Accepted Answer

Luna is the ultra-fast, cost-efficient edge model. Terra is the balanced daily driver offering high performance for cheaper. Sol is the flagship model with an 'Ultra' setting for complex parallel multi-agent orchestration.

Question 8

Does the OpenAI Academy include hands-on labs?

Accepted Answer

Yes. Hands-on terminal labs are built into the lessons - call the Responses API with curl and invoke frontier models with the Ultra setting using real, vendor-verified commands. Labs include objectives, hints, solutions, and XP rewards. No sign-up or setup needed.
