While AI code generators still aren't perfect, they undoubtedly have been one of the most practical and early use cases of LLMs.

From the release of GitHub Copilot in 2021 to the massive adoption of ChatGPT in 2022, many developers say AI code generators have 10X'ed their software development speed & workflows.

From suggesting code, providing explanations, adding comments, and more, these AI code generators have not only made streamlined software development, but have also made learning how to code significantly more accessible.

With the rate at which AI is improving, learning how to incorporate AI coding tools into your workflow is a must if you want to stay competitive in the coming years.

In this guide, we'll look at the top AI code generators to watch, including their key use cases, benchmarks, and more. Specifically, we'll look at:


ChatGPT

ChatGPT is of course a general purpose chatbot, although it's still one of the most practical & skilled AI code generator available. Also, since many other AI coding tools are built on top of the GPT-4 API, let's look at a few key benchmarks.

As OpenAI highlights, on the HumanEval Python coding tasks GPT-4 was able to generate correct code 67% of the time without any examples (i.e. zero-shot).

Code Interpreter

Another key feature of ChatGPT for coding is the Code Interpreter tool, which is available directly in ChatGPT 4 and the API. As the OpenAI docs highlight:

Code Interpreter allows the Assistants API to write and run Python code in a sandboxed execution environment.
Code Interpreter allows your Assistant to run code iteratively to solve challenging code and math problems. When your Assistant writes code that fails to run, it can iterate on this code by attempting to run different code until the code execution succeeds.

While only available for Python at the moment, it's likely we'll see support for many languages in the coming months, and many AI coding tools will undoubtedly be built on top of this.

Bard

Bard is another general purpose chatbot with notable coding capabilities. In particular, Googles recent introduction of AlphaCode 2, powered by the Gemini Pro language model from DeepMind, is a state-of-the-art model designed for competitive programming.

In competitive scenarios, AlphaCode 2 managed to solve 43% of the problems on Codeforces, outperforming 85% of human programmers who participated in the same challenges. Gemini and AlphaCode 2 are now freely available for you to try in Bard.

Github Copilot

Released in October 2021, GitHub Copilot is one of the first and most widely-used AI coding assistants. The latest version of the model is powered by a custom model in collaboration with OpenAI, Microsoft Azure AI, and GitHub, and has surpassed its previous reliance of the OpenAI Codex model.

This newer model offers a 13% latency improvement over its predecessor, allowing for even faster code suggestions to developers. This updated GitHub Copilot is a a powerful tool for developers that can significantly boosting productivity, speeding up task completion, and improving overall code acceptance rates.
