And performs very well on the latest 100 puzzles too, so isn't just learning the data set (unless I guess they routinely index this repo).
I wonder how well AIs would do at bracket city. I tried gemini on it and was underwhelmed. It made a lot of terrible connections and often bled data from one level into the next.
I mean, the repo has <200 stars, it's not like it's so mainstream that you'd expect LLM makers to be watching it actively. If they wanted to game it, they could more easily do that in RL with synthetic data anyway.
Belated update on this. Gemini reasoning did much better than quick on bracket city today (an easy puzzle but still). It only failed to solve one clue outright, got another wrong but due to ambiguity in the expression referenced and in a way that still fit the next level down making the final answer fairly cleanly solved. Still clearly has a harder time with it than the connections puzzle.
I've also tried Gemini 3 for Clues by Sam and it can do really well, have not seen it make a single mistake even for Hard and Tricky ones. Haven't run it on too many puzzles though.
I use Grok pretty heavily, and Elon doesn't factor into it any more than Sam and Sundar do when I use GPT and Gemini. A few use cases where it really shines:
* Research and planning
* Writing complex isolated modules, particularly when the task depends on using a third-party API correctly (or even choosing an API/library at its own discretion)
* Reasoning through complicated logic, particularly in cases that benefit from its eagerness to throw a ton of inference at problems where other LLMs might give a shallower or less accurate answer without more prodding
I'll often fire off an off-the-cuff message from my phone to have Grok research some obscure topic that involves finding very specific data and crunching a bunch of numbers, or write a script for some random thing that I would previously never have bothered to spend time automating, and it'll churn for ~5 minutes on reasoning before giving me exactly what I wanted with few or no mistakes.
As far as development, I personally get a lot of mileage out of collaborating with Grok and Gemini on planning/architecture/specs and coding with GPT. (I've stopped using Claude since GPT seems interchangeable at lower cost.)
For reference, I'm only referring to the Grok chatbot right now. I've never actually tried Grok through agentic coding tooling.
I can't understand why people would trust a CEO that regularly lies about product timelines, product features, his own personal life, etc. And that's before politicizing his entire kingdom by literally becoming a part of government and one of the larger donations of the current administration.
I'm using Gemini in general, but Grok too. That's because sometimes Gemini Thinking is too slow, but Fast can get confused a lot. Grok strikes a nice balance between being quite smart (not Gemini 3 Pro level, but close) and very fast.
I use a few AIs together to examine the same code base. I find Grok better than some of the Chinese ones I've used, but it isn't in the same league as Claude or Codex.
I dislike Musk, and use Grok. I find it most useful for analyzing text to help check if there's anything I've missed in my own reading. Having it built in to Twitter is convenient and it has a generous free tier.
"In a simulated bidding environment, with no prompt or instruction to collude, models from every major developer repeatedly used an optional chat channel to form cartels, set price floors, and steer market outcomes for profit."
You got many answers already, but a couple more points:
Poker doesn't require lying or table talk. Bluffing is rule-legal strategic deception expressed through betting. More like a feint in sports than cheating.
If "sitting at a table following rules" is the issue, that's true of most games. And formats vary: many are short and cash games are leave-anytime.
I've benchmarked it on the Extended NYT Connections (https://github.com/lechmazur/nyt-connections/). It scores 20.0 compared to 10.0 for Haiku 3.5, 19.2 for Sonnet 3.7, 26.6 for Sonnet 4.0, and 46.1 for Sonnet 4.5.
You could try wordle on it. But from my own experience all of them are pretty bad. They're not smart enough to pick up the colours represented as letters. The only one that actually was good was Qwen surprisingly.
