This is what we mean when we say the league has never been as deep as it is right now.

Indeed. Always a scam.

Very excited for this

Yet still no Instagram for iPad 🤣

Okay wtf is going on

We got a call from @xai 24 hours ago “We want to test Grok 4 on ARC-AGI” We heard the rumors. We knew it would be good. We didn’t know it would become the #1 public model on ARC-AGI Here’s the testing story and what the results mean: Yesterday, we chatted with Jimmy from the xAI team, who wanted us to validate their Grok 4 score. They did their own testing on the ARC-AGI-1 & 2 public evaluation set To validate their score (and measure possible overfitting), we self-tested the new model on our semi-private evaluation set We walked them through our testing policy: * No data retention * Model checkpoint must be intended for public use * Temporary increase in rate limits for burst testing They were on board, so we got started Initially, we ran into timeout errors with normal requests, so we switched to streaming. That resolved the issue So, what do these results mean? First, the facts: Grok 4 is now the top-performing publicly available model on ARC-AGI. This even outperforms purpose-built solutions submitted on Kaggle. Second, ARC-AGI-2 is hard for current AI models. To score well, models have to learn a mini-skill from a series of training examples, then demonstrate that skill at test time. The previous top score was ~8% (by Opus 4). Below 10% is noisy Getting 15.9% breaks through that noise barrier, Grok 4 is showing non-zero levels of fluid intelligence But the mission isn’t over. We need new ideas to solve ARC-AGI-2. Scale alone won’t get us there Come work on ARC-AGI with us

Where's the API?! You said it was live! @elonmusk

I knew it. The worst.

Surprise! Grok 4 is not dropping on the API today. I'm sure it will happen in a few months...

For anyone interested in AI, I can't recommend @natebjones YT channel enough. A refreshing voice in a forest of ill-informed channels

@markgurman How does @theo feel about this

Apple dramatically turned down the Liquid Glass. I don’t like the change at all.

It is incredible that Apple design decisions developed over multiple years can be influenced by a week of Twitter and YouTube commentary.

Had anyone ever done this before? Take two weeks off, then come back to work?

I've used Pocket for managing my "read later" list for over 15 years. It shuts down today. RIP to a real one.

The fireworks in your mind. 🧠✨ This sparkling video shows the neurotransmitter glutamate being released into synapses, made possible by an indicator developed by @abhi_aggarwal1, @PodgorskiLab, and team. #HappyNewYear #NYE

Quitting programming as a career right now because of LLMs would be like quitting carpentry as a career thanks to the invention of the table saw.

Now the only question is did they achieve these with cons@n or no..

Grok-4 benchmark leak just dropped. -HLE: 35 → 45 w/ reasoning -GPQA: 87 → 88 - AIME’25: 95 - SWEBench (Code model): 72 → 75 If validated, Grok-4 is flirting with Claude Opus territory. Release looks imminent. xAI is officially in the frontier model race.

would you rather fight 1000 4o-mini sized agents, or 1 o3-pro sized agent?

Talk is cheap, ship research and models
