Is the GPT-4o API Still Available in 2026?

Yes. The GPT-4o API is still available in 2026. OpenAI retired GPT-4o from ChatGPT in February 2026 but kept the model on the developer API. This article confirms status, how to access it, and how chat apps like Get4oBack use it.

What changed in 2026

OpenAI removed GPT-4o from the ChatGPT product. You can no longer select it in the ChatGPT UI. The API, however, did not go away. Developers and apps that use the API can still call the GPT-4o model. So "still available" means: on the API, yes; in ChatGPT, no. If you want to use 4o, you do it via the API directly or via an app that uses the API.

How to use the GPT-4o API

If you are a developer, you need an OpenAI account, a paid API plan, and an API key. You send requests to the API with the model set to GPT-4o and pay per token. If you are not a developer, you can use a chat app that already uses the API. Get4oBack is one: we call the GPT-4o API and give you a chat interface. You get the same model without managing keys or code.

Chat apps that use the API handle rate limits, retries, and billing on your behalf. You get a monthly token allowance instead of raw per-token billing, which many users find easier to plan for. The model and quality are the same whether you call the API yourself or use an app like Get4oBack.

Will it stay available?

OpenAI has not announced any plan to discontinue the GPT-4o API. If they ever do, products that depend only on it would need to adapt. Get4oBack is prepared: we offer Our-4o, a continuity model that replicates the 4o experience, so you keep the same feel even if the API is retired.

Chat apps vs API directly

Using the API yourself means managing keys, rate limits, and per-token billing. A chat app like Get4oBack wraps the same API in a ready-made interface: you get a monthly token allowance, no key to store, and features like history, folders, and export. The model and quality are identical. Most non-developers prefer the chat app route; developers sometimes use both - the API for their product, Get4oBack for personal chat. Either way, 4o is still available in 2026.

Checking API status yourself

OpenAI's status page and developer docs are the source of truth for API availability. If you rely on 4o for work, bookmark them. Get4oBack and other API-based apps use the same endpoints; if the API is up, we can serve 4o. We also offer Our-4o so that if the 4o API is ever deprecated, you still get a continuous experience. For day-to-day use, just open the app - no need to check API status unless you are debugging.

Summary

The GPT-4o API is still available in 2026. Use it via the OpenAI API (developers) or via a chat app like Get4oBack (everyone else). ChatGPT no longer has 4o; the API does.
