Top post: @kimmonismus “It is absolutely crazy how the last two weeks have changed the entire future. It is unprecedented that access to "frontier" models was cut off,and presumably remains cut off forever. It feels like a watershed moment, as if access to the highest level of human intelligence had been blocked. Open source is the future. Open source is the solution. The last two weeks have powerfully demonstrated this.”

Top post: @levie “Some good best practices here on AI token cost optimization. None of these happens though without a deep understanding of the underlying work being done in a non-abstract way. The ultimate implication is that a layer between the work itself and the underlying intelligence needs to deeply understand your workflows, context, and business process. Now, each individual company doing this on their own is unlikely to be effective at scale, so as a consequence, this is effectively the playbook for any applied AI company right now. By evaling the models for the applied use cases, deeply understanding the domain, having tuned UX and features for the use case, and having the ability to support adoption and change (via FDEs), allow this layer to add a ton of value. And as a result, enterprises get higher ROI because you actually can get *more* intelligence per dollar by having optimal architecture and workflows. There will be many horizontal and vertical versions of this approach. Huge opportunity right now.”

Top post: @natolambert “I've been getting a lot more hate than usual as I try to speak my mind about regulatory capture / unintentional attacks on open-source. It's pretty sad, as there are few people in AI that can speak their mind (most companies say they cannot) and I know many people agree with me silently. I also get people saying that you only say that because it supports the outcomes you want, in a weirdly derogatory way. Of course this is true, but I'm choosing to turn down meaningful wealth so I CAN fight for these values, working at non profits to speak my mind. Building a future that is more inclusive, diverse in the application of AI, and fairer for our children. I may not always be right, but it has been clear to me for a while that more openness right now will help way more than supporting the closed causes. I continue to re-visit this and don't think everything should be open like some of the open-source absolutists. I also don't like a lot of my comrades making fun of anthropic, calling the people there evil, etc. Those are not the case. Trying to stay the course!”

Top post: @Suhail “I've started doing a lot of async learning where I'll take every interesting blog post, tweet, arxiv paper and ask AI to teach me it with a specific prompt. I never read it in the moment, I just queue it up for later. Then when I have a block of time (in an uber, before bed, etc), I'll go and read it vs doomscrolling X. This is somehow become better than saving links in Notes or something because when I finally have time to read it, there's this highly approachable artifact for me to dive into, read, and ask follow up questions. I feel like I am learning at a much faster rate than I ever have before. Even if the content was poorly written, AI can fix it to your liking and adapt to your experience level.”

Top post: @kimmonismus “That reads like a solid initial assessment. GPT-5.6 will likely offer a better price-performance ratio than Fable 5; however, given the recent announcement that Fable 5 already has a newer version (5.1?), it seems logical that Fable will likely remain the better overall model for the time being. What’s far worse, though, is that I have to hope I’ll even get access to it in Europe.”
