Earlier this week, Google made a splash when it released its TensorFlow artificial intelligence software on GitHub under an open-source license. Google has a sizable stable of AI talent, and AI is working behind the scenes in popular products, including Gmail and Google search, so AI tools from Google are a big deal.

Today on GitHub, TensorFlow, primarily written in C++, is the top trending project of the day, the week, and the month, having accrued more than 10,000 stars in about one week.

But there are several other open-source tools to choose from on GitHub if you want to improve your app with deep learning, a type of AI that involves training artificial neural networks on a bunch of data and then getting them to make inferences about new data.

Here’s a rundown of some other notable deep learning libraries available today.

The big ones

The long tail

What am I leaving out?

There are other frameworks available today — these are just the most interesting ones I’ve encountered — and more will surely emerge in the future. Let me know what’s missing, so I can update this post accordingly.
