“Grok is getting better fast [@VictorTaelin] Sonnet-3.7 is great, and I do think it is the best coding model. But, truth is, Grok-3 is more intelligent. It is the only AI that can solve my hard prompts. The Bitter Lesson is real. If xAI keeps these 200k H100 improving Grok nonstop... I bet it will be uncontested by 2026.)”

We found @xai's @grok 4 to be the clear SOTA winner, scoring first place on both 2024 and 2025 exams. 🥇📊👏”

“@WallStreetApes @grok Because all AIs are trained on a mountain of woke bullshit on the Internet that is very difficult to remove after training even IF you care a lot about truth, which @xAI does. We have to retrain the foundation model on cleaned up data.”
