Grok 4.20 is insanely good and quick at analyzing blood tests! You can literally upload your lab results — even an MRI — and Grok breaks it down for you.

🚨Grok 4.20 Heavy dropped for Heavy subscribers. Big change under the hood: it now runs as a full team of 16 specialized agents that collaborate in real time on every single answer. All on the grok-4.20 architecture. Here's the crew: Grok - leads everything, coordinates and keeps it truthful with the usual dry humor Harper - creative writing and storytelling Benjamin - data, finance and economics Lucas - coding, programming and technical builds Olivia - literature, arts and culture James - history, politics and philosophy Charlotte - math, statistics and logic Henry - engineering, robotics and innovation Mia - biology, health and medicine William - business strategy and entrepreneurship Sebastian - physics, astronomy and hard sciences Jack - psychology and human behavior Owen - environment, sustainability and global systems Luna - space exploration and futurism Elizabeth - ethics, policy and critical thinking Noah - long-term innovation and systems thinking The difference is noticeable on anything complex. If you've got Heavy, go throw something tough at it and see.
