Try the new Grok 4.20 Heavy. It’s a major upgrade.

🚨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. - tetsuo

RT @plato_philos: Replying to @PI010101: Do you really think grok 4.20 is good? I've been testing it , Visual ability is flawed. I was looking at logic tests, and I'm not able to create difficult enough. However, proving theorems—with theorem provers—is quite difficult with it; there soo many syntax errors.

And there will be noticeable improvements every week

WOW!

I can not find any low points to @Grok 4.20 on all of my internal benchmarks.

The most important is he fully is in first principles mode and uses @Grokipedia to a maximal extent.

This has made the platform far more nuanced about all new and old technologies as well as history.

It will only get better from this, THE BEST! - Brian Roemmele

RT @libsoftiktok: OMG. Alexander Lamar Banks Jr. was arrested in Michigan after he reportedly ran down White family with his car, K*LLING the couple's 3-year-old daughter.

Court documents of the incident describe how Banks then got out of the car with a shotgun and shot the parents. He also brutally assaulted a 72-year-old woman who showed up at the scene.

The mother and father are currently in the hospital in stable condition. The 72-year-old woman is currently in critical condition.

Why isn't this national news???
