New Gemini looks pretty good! 3 pro also looked good though and suffered pretty bad in tool-loop type environments (Claude-code-like tools).
This is kinda a large jump to just stick a .1 in imo, if the agi-2 score is to be believed

Four-in-a-Row is a “solved” game. Frontier LLMs still can’t play it reliably.
📢 We just launched a new Game Arena leaderboard to test how models reason step-by-step, maintain a mental board and plan moves - no minimax, no game-tree shortcuts.

I just finished this book. I really tore through it; could hardly put it down. Quite gripping story-telling, great writing style.. even from the first chapter.
I recommend everyone using social media read this book. Having used Facebook from the early days up to ~2015, it was quite eye-opening. 😳

They are from an old game called Emerald Mine (inspired by Boulder Dash).
I made a little video to explain it and show how to get Rocks n' Diamonds.
