# New GPT‑3 capabilities: Edit & insert

We’ve released new versions of GPT‑3 and Codex which can edit or insert content into existing text, rather than just completing existing text.

We’ve released new versions of[GPT‑3⁠(opens in a new window)](https://beta.openai.com/docs/engines/gpt-3)and[Codex⁠(opens in a new window)](https://beta.openai.com/docs/engines/codex-series-private-beta)which can edit or insert content into existing text, rather than just completing existing text. These new capabilities make it practical to use the[OpenAI API⁠(opens in a new window)](https://beta.openai.com/)to revise existing content, such as rewriting a paragraph of text or refactoring code. This unlocks new use cases and improves existing ones; for example, insertion is already being piloted in[GitHub Copilot⁠(opens in a new window)](https://copilot.github.com/)with promising early results.
