Watch Tesla’s AI Day 2022 event at 9:15PM ET

Tesla is holding another AI Day, and it’ll be particularly easy to tune in. The automaker is streaming its 2022 event tonight at 9:15PM Eastern on YouTube (below) as well as its website. Elon Musk has warned the presentation will be “highly technical” and could last six hours, but you may have multiple reasons to watch even if you’re not fond of diagrams and in-depth explanations.

Notably, Musk said in June that Tesla pushed AI Day to September 30th in hopes of having a functional Optimus humanoid robot. It would just be a prototype, but it would show that the company’s vision of an autonomous helper exists beyond pretty 3D renders. The machine is meant to handle dangerous or monotonous tasks without requiring step-by-step instructions.

You could also see improvements to Tesla’s vehicle technology. The company’s Full Self-Driving feature is still rough, and Tesla might explain how it plans to refine the system. You could also see upgrades to Autopilot driver assistance. Behind the scenes, the company may expand the capabilities of the Dojo supercomputer it uses to train vision-based AI systems.
