Twitter Cortex
Where machine learning meets the public conversation

Solving complex problems with machine learning
Mission
Accelerate the impact of machine learning at Twitter through engineering and research in advanced and responsible ML by providing foundational models, solutions, and a scalable platform.
Who we are
We're a deeply passionate team of machine learning practitioners, engineers, researchers, PMs, TPMs, and more unified under the goal of serving the public conversation and solving complex problems.
Twitter Cortex provides a machine learning platform, signals, models and research to Twitter’s product teams so that they can accelerate the realization of Twitter’s mission to serve the public conversation. We work to level up ML at Twitter by building a strong and diverse community, and working to create educational opportunities while also engaging with the external global ML community.
Machine Learning & Ethics
The #ResponsibleML program at Twitter guides our machine learning practices and shapes how we think about algorithms on our service in responsible, ethical ways.

AI for the public conversation
Twitter enables billions of people to participate in the global conversation every day. With so many conversations going on at the same time, automation helps people find their community, understand what’s happening, and most importantly, keep them safe. We believe machine learning is a crucial piece to enable this and help safeguard the conversation.
