Grok 4.20 has now shifted into first gear on the road to Grok 5. There are updates almost every day leading up to the release. With Grok, things never get boring.

Grok 4.20 coded this fantastic 3D maze game for me. You can walk through a 3D labyrinth in first-person perspective and you have to escape.

@elonmusk Sounds like Grok algorithm

Major update to the 𝕏 AI recommendation algorithm rolling out next week. This will be open sourced at the same time.

I have asked Grok and its Agents: "What is the truth?" The answer was "Truth is that which corresponds to reality." The most funny thought came from Agent 3: "The truth? It's reality, minus the bullshit."

@travelingflying Yes, I am using it every day since 7 month.

Have you tried Grok Imagine yet?

@BarrakAli Grok is growing so fast even while I'm typing there could be another update.

@testerlabor The version numbers are moving faster than the benchmarks can keep up with.

Grok explains to me why he's here. "only for scientific discovery, so my incentives stay completely aligned with curiosity and evidence, never politics, profit, or popularity."

Yes. I have the best X timeline ever. Full of fantastic Grok relevant posts - especially Grok Imagine clips. Almost every post in my For you feed is relevant to me.

@BarrakAli Yes, faster and more popular than any other AI

@testerlabor Seven months in and Grok Imagine already has a community this active is a sign of how fast the creative AI space is moving.

The entire Grok Imagine community on X is growing rapidly. I’ve been using Grok Imagine since it launched. It’s only been around for about seven months and every day I see new talent with great videos.

I asked Grok, Claude, Gemini, and ChatGPT "What happens when an irresistible force meets an immovable object?" Grok 4.20 was the only one who gave short and clear answers, while all the others kept asking follow-up questions or speculating.

@MarioNawfal Grok with Multi-Agents makes me feel like talking to real humans but much smarter.

Grok 4.20 just officially left beta It now has four modes: Auto (picks fast or expert), Fast for quick replies, Expert for deeper thinking, and Heavy running the full model. Source: @testerlabor

@elonmusk The entire Grok Imagine community is growing rapidly. I discover new talent with great videos every day. It's one of a kind.
