OpenAI Codex

OpenAI Codex is a model available on OpenAI’s playground to help users write code. It is descended from GPT-3 and is more fine-tuned for coding purposes than GPT-3, allowing it to be used a brilliant coding assistant. OpenAI Codex is proficient in multiple programming languages and can be used for tasks such as transpilation, code explanation, and code refactoring. It is currently available in private beta via API and on the Playground section of OpenAI’s website. To get access to it, sign into your OpenAI account and head to the playground, under the model setting you will be able to switch it to one of the Codex models.

Is OpenAI Codex Free?

During it’s initial testing phase, Codex was free for general use. Since it’s now on the OpenAI playground, you can access it with the $18 in free credit you receive when you open your OpenAI account. Once you’ve used up those credits, you’ll have to purchase more to continue using Codex.
