Starship flights going monthly
President of @SpaceX Gwynne Shotwell on CNBC this morning on Starship: • Starship Flight 13 is about a month away. • Expect to see hopefully see Starship flights on a monthly basis after that. • SpaceX hopes to attempt orbital injection on Flight 14. • It’s realistic to have Starship reaching orbit by the end of 2026.

but why is this, specifically, this regulation? the model can be trivially jailbroken into a hacking machine that threatens national security, but it's fine if 300m americans have access to it? it's fine if american felons use it but not canadians on work visas? what is the regulatory framework now? how will future decisions be made? is gpt 5.5 safe? anthropic asked for thoughtful measured far-thinking partnership with governments on the shared problem of safely delivering this technology, not blunt capricious flailing.

Wow this aged well
StackOverflow's sale last year ended up being well-timed. The boilerplate / example code use case is increasingly better served by copilot. The "why isn't my code working" use case is about to get eaten by GPT-4 chatbots. What's left?

Lotta focus on SpaceX ipo, rightly, but I looked more into the humanoid robot market, and: @Tesla is going to get so much more valuable.
Optimus will be the biggest product ever made. A general-purpose humanoid robot that can do useful work at scale will change the economics of labor & manufacturing. Goal is to get Optimus to high-volume production as fast as possible. If you’re great at AI, engineering, or manufacturing & want to build this, join us! → tesla.com/careers/search/?qu…

Wow. Inherited memory via proteins in E. coli?
Jun 11
Found research from May that shows e. coli "remember" environmental conditions their ancestors lived through and behave differently because of it, all without a brain, neurons, or a nervous system. Inherited proteins handle the memory. The mechanism is what's so cool. Different cellular components relax on different timescales, so the cell integrates its history as a power law instead of a single decay constant. This is an extremely elegant expression of memory as a biochemical hidden state, emergent from ribosome dynamics, that lets a granddaughter cell respond to stress it never personally experienced. It is also oddly close to the logic behind recurrent neural networks. My main takeaways are that memory might predate minds and a growing belief that AI is convergent with biological intelligence. paper: journals.aps.org/prxlife/abs…

Or “Fab 5”
Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Its capabilities exceed those of any model we’ve ever made generally available.

Trampoline Rocket retweeted
This is a super exciting release - Claude Fable 5 is the same underlying model as Mythos but with added safeguards. The benchmarks are great and it's SOTA on everything by a margin but I'll add that *qualitatively* also, this is a major-version-bump-deserving step change forward (imo of the same order as Claude 4.5 was in November), peaking especially for long problem-solving sessions on very difficult problems. You can give it a lot more ambitious tasks than what you're used to, the model "gets it" and it will just go, and it's never felt this tempting to stop looking at the code at all (but don't do this in prod!). The model still has quirks that people will run into and the safeguards are configured to be a little too trigger happy for launch, which can hopefully be tuned over time. I feel a lot of things changing as working software increasingly comes out on a tap. The Jevon's paradox kicks in and I feel my own demand for software growing substantially. You can ask for anything - explainers, visualizers, dashboards, bespoke single-use apps (e.g. a full wandb that is hyper-specific just for your project), you can 10X your test suite, auto-optimize code, run giant research projects with custom HTML for the results, anything! "Free your mind" (Matrix ref). Really looking forward to all the things people build!

Fable 5 is state-of-the-art on nearly all tested benchmarks, with exceptional performance in software engineering, knowledge work, scientific research, and vision. The longer and more complex the task, the larger Fable 5’s lead over our other models.

New Mythos 5 doing a bunch of real science with only high-level human overview. Amazing.
Replying to @AndrewCurran_
Quotes from the release today: 'Using Mythos 5, our internal protein design experts accelerated aspects of the drug design process by around ten times. In one example, they found that Mythos 5, with protein design and bioinformatics tools but no human assistance, matches or beats skilled human operators. In doing so, the model executes all of the tasks that are normally completed by a scientist: choosing binding sites, selecting and running protein design tools, and recovering from failures along the way.' 'During early testing, Stripe reported that Fable 5 compressed months of engineering into days. In a 50-million-line Ruby codebase, the model performed a codebase-wide migration in a day that would otherwise have taken a whole team over two months by hand.' 'Mythos 5 is our first model to consistently produce novel, compelling scientific hypotheses. In blinded head-to-head comparisons against Opus-class models, our scientists preferred Mythos’s molecular biology hypotheses ~80% of the time, and have advanced several to experimental evaluation. In the meantime, one Mythos hypothesis—a novel mechanism for an E. coli protein—was corroborated in a study from a lab independently working on the same problem.' 'Mythos 5 conducted novel genomics research in over a week of largely autonomous work. It assembled single-cell data for millions of cells spanning 138 animal species and designed and trained a custom machine learning model to identify cells performing the same role in even distantly related organisms. With only high-level human input, Mythos 5’s trained model outperformed a recent model published in the journal Science—despite being 100 times smaller. We intend to publish these results in the coming months.'

It's finally out!!! @METR_Evals found that more than half of SWEBench results is unmergeable slop. FrontierCode represents over 1000 hours of maintainer validated software engineering work most frontier models cannot yet solve, much less solve with high quality. Cog had IOI Gold medalists and top code maintainers Look At The Data — FrontierCode includes 3000 rubrics covering code quality and anticheat reward hacking plaguing other benchmarks. FC Diamond is so hard that Opus 4.8 scores 13.8%. Three eras of AI coding : Three eras of benchmarks 2021 • Autocomplete : HumanEval 2023 • Passing Tests: SWEBench, TerminalBench 2026 • Maintainable Code: FrontierCode to me the most beautiful chart when I requested a special historical run into all extant old models, the data was finding that the easiest third of FC tasks (in FC Extended) were rapidlly and suddenly solved over late 2025 - Opus almost doubled from a 41% pass rate to 74% in 4 months. This describes the "WTF happened in Dec 2025" vibe shift that a lot of folks from @dhh to @karpathy have called out: it is the difference between getting 95% success in 2 rerolls vs 6, making it finally feasible to go up the next layer of abstraction in agentic coding, eg @GeoffreyHuntley's ralph loops or @bcherny's /goals or @steipete's "loops that prompt your agents" without fearing too much that things go off the rails. My guess: as AI accelerates from here, each FrontierCode tier will saturate in sequence, hopefully ~annually. I've already asked the team to prepare FrontierCode 2027.... The old mountains will be destroyed. Their rubble becomes regolith. And from that regolith, the next model forest grows. Circle of life.
Introducing FrontierCode: a coding eval that raises the bar for difficulty & quality. Each task took 40 hrs of work by leading open-source maintainers. Models write sloppy code that works but isn’t maintainable. Our eval is first to measure: would you actually merge this code?
