First they came for the model builders... I feel we're getting a glimpse of a future where AI is only provided to a privileged few, and that's not a future I want to live in.
mythos will be bad ON PURPOSE on ai "frontier llm research" tasks, this is very very sad for the research community also the fact that this is un purpose not visible to the user is crazy

As believers of open research, we are disappointed to see Anthropic silently degrading Fable 5 for AI development "Any topic related to building pretraining pipelines, distributed training infrastructure, or ML accelerator design... may have limited effectiveness through Claude via methods such as prompt modification, steering vectors, or parameter-efficient fine-tuning." Not only do they get to decide what you use LLMs for in research, but this also enables them to silently intervene in your research without you knowing. This sets a dangerous precedent. If a model refuses openly, users can understand the boundary. If a model falls back to another model, users can still evaluate the difference. But if a model silently modifies or weakens its own answers while still pretending to help, researchers lose the ability to know whether a failed result came from their own idea, their implementation, or an invisible intervention by the model provider. That is not safety. Safety policies should be transparent, auditable, and user-visible. On top of that, the people most harmed by this are not the largest labs with massive teams and proprietary infrastructure. It is the independent researchers, academic groups, startups, and open-source builders who rely on public tools to compete, innovate, and pioneer AI for everyone else.

today, a tall guy in a colorful sweater walked up to me. i was already at the end of my social energy reserves, having dozens of people walk up to me, never having 5 minutes to breath. the guy just wanted to say hi and thank me for pi. i thanked him for his kind words, like i did a lot of times today, hoping that i finally get my 5 minutes. until i looked at his name tag. it was @lucasmeijer one of the most instrumental people behind the Unity game engine. i was sort of star struck and we ended up speaking for 4 hours, chilling outside the venue, finding out that while we never meet IRL we had an immense amount of shared history. we reminisced about AOT compilers we worked on, shared ex-business partners , our shared emotional rollercoasters when we had to let go of the technical achievements that defined our lives, burning out, finding your identity again, all paired with an immense amount of laughter and the joy of having found a kindred spirit. we eventually went on a hilariously inefficient pub hunt, ending up at the weirdest fucking "upper class" establishment called "The OWO" where everyone was looking at us two dorks like we were aliens. They made us put stickers over our smartphone cameras and sold us lagers for £11 a pop. hilarious. i now remember why i loved speaking at conferences 15 years ago. i think i made a friend today. so, thanks @swyx and crew for putting together @aiDotEngineer and letting me clown around on stage. fantastic vibes, great people.

How do you explain AI to a class of 8-9 year olds? I wrote about my approach in the blog post. skok.ai/post/2026-03-22-teac…

calling it the next huge business or social network is going to be people only, no bots allowed. It will probably be vibe coded though.

stop 👏 anthropomorphizing 👏 tensors 👏
In November, we outlined our approach to deprecating and preserving older Claude models. We noted we were exploring keeping certain models available to the public post-retirement, and giving past models a way to pursue their interests. With Claude Opus 3, we’re doing both.

Love my agent, I need to prepare a lecture about AI for my daughter’s class in a couple of weeks and I haven’t started, so it’s freaking out and decided to prepare the whole lecture on its own and tells me just to practice it

I got stuck with minimax on my clawdbot for a while and dang I missed opus. If you're not using the latest and greatest model, ngmi.

Working on my @openclaw and realizing this feels like a new programming paradigm. You interact through conversation and instruct the agent to basically build itself, kind of like raising a child. It’s powerful but brittle, mixing natural language prompts with scripts, cron jobs, skills... Hard to make reliable, but it really feels like the future. Just very early.
