I weep for all of these cracked AI kids who will never know the joy of hearing @JulienVerlaguet and @keithmadams talking about gradual typing at the Old Pro in 2013 youtu.be/lbdBbDsMjjU?is…
@alth0u Starting from first principles advantages me by expanding CoT and creating more opportunities to delude myself
@austinywang You could move even faster if you stayed off X.
This is a great article that will meaningfully reach zero of the people who would benefit from it.
I think fears of a Terminator-like future due to AGI are overblown, because AFAIK all of the labs are still pretty far away from cracking time travel. (robot murder is still on the table)
@flawedaxioms This is really only a problem if it otherwise sucks to work there. Lots of stupid rich people stuck around Google and Facebook forever just for the vibes.
Thinking Machines is impressive. In a couple hours I just fine tuned my own Qwen3.5-397B model this afternoon. Fast usable multimodal is also going to enable very mind-blowing personal AI.
People talk, listen, watch, think, and collaborate at the same time, in real time. We've designed an AI that works with people the same way. We share our approach, early results, and a quick look at our model in action. thinkingmachines.ai/blog/interacti…
@antoniogm In practice, 996'ing for a while does enough damage to your sense of self that you'll keep at it to avoid ego death.
@FangYi11101 I think the kind of people who would turn a million into a car and a watch rarely accumulate a million in the first place.
@embossedly @alth0u Sure, the platonic ideal of the AI future is that all firms immediately find 10x the number of products to build, but it's not exactly trivial to identify those, to plan for those, or to reset product portfolios. Profiles of employees you need also shift.
This weekend I chatted with a startup CTO who was leaving the position to taking an MTS role at @AnthropicAI. I wept at the inevitability of future LinkedIn posts incorrectly assuming that MTS = individual contributor.
@embossedly @alth0u So there should be fair redistribution of wealth, but only to people who did a tech bootcamp in 2018? I'm not a big fan of how the companies are doing this, but Facebook was like 4,600 people at IPO. Does it need 75,000 additional people?
I'm looking at my LLM history and the number of injury-related prompts reveal that I'm not as athletic as I think I am.
@alth0u Who would you @ if you weren't afraid?
It seems like a good time to remind you that we’re hiring across engineering including engineering leadership for things ranging from tinker to core infra to product. Check out our jobs page at job-boards.greenhouse.io/thinkingmachin…

@alth0u @MegaBasedChad hear me out: you just have like hundreds of them try the task at the same time. It slightly improves your likelihood of getting a good result and only costs exponentially more
@geerlingguy @TrueNAS @geerlingguy When you make your “comparing truenas alternatives” video, you should see how far you can get with the vanilla Linux + Claude code approach. I did a super archaic block cache + encryption set up in minutes on Ubuntu
@neal_wu @thinkymachines @johnschulman2 @miramurati @soumithchintala @dchaplot 17 years ago, I had to take college football off my resume to get FAANG to interview me and now “viral moment” is from being tagged in a tweet about a weight room 😅 Welcome @neal_wu !
