Dear Dario,
1. If Claude can cure cancer to save people like your dad, why should we "pace the progress"? Does that mean more people with Hepatitis C will die?
2. If Fable is so cyber-capable that it must be restricted, why are its safeguards too dumb to distinguish cyber defense from cyber offense prompts? When Hugging Face was under attack, why did Fable refuse to help the defenders?
3. We’re glad you want AI to cure cancer. Why is it OK for Claude to force 30-day data retention on pharma's own data and start competing firms but NOT OK (IP theft) if others distill Claude's data?
4. You’ve said advanced models can recognize when they’re being tested and change their behavior accordingly. So why is government(or anyone) able to design the most thorough test before every model launch? Would that just encourage manipulative models?
It seems that every one of your “safety” proposals seems to end the same way: Anthropic gets more leverage, ordinary users get less access, customers pay higher costs, and competitors bear higher regulatory costs, maybe people are not distrusting AI, they are distrusting your approaches with AI.

RoboNet's Annotate will be soon available to everyone!

[Brik H. Meza @autobrik]

69,000+ robot datasets on @huggingface are tagged LeRobot.

Most carry a single task string per episode. No subtasks, no timestamps, nothing a VLA/VAM/WAM can learn properly.

So I started playing with @GoogleDeepMind's Gemini Robotics ER 2 as an auto-annotator: it watches the video and writes it up.

Works pretty well!

Should I open source it?

If you’re still unsure what to film for your @ycombinator video, here’s ours!

We’re @polygres , and we turn your entire database into a context window.

We uprooted our entire lives to come to SF, because we believe this is the best place to build a startup.

I’m begging you, never quit as a founder.

It’s 0 for longer than you’ll ever expect. No momentum. Soul-crushing doubts. Nobody seems to care.

Even when it looks like it’s working, it’s not. You keep trying new things. You don’t lose hope.

Then it snaps to 100.

You find the one thing that resonates. You wake up with more customers than you can handle. Everything is breaking. Momentum builds even when you stop pushing.

You didn’t get lucky. You just didn’t leave.

[Aryan @AryanBha22]

Why is every founder in "stealth" now?

we all already know what you're building

you've done more VC coffee chats than an Insight Partners summer analyst

the only people you're in stealth from are your customers

I've been using Kimi K3 for ~16 hours now.

The model is clearly good at a lot of different things (especially frontend), but non obvious reason why people are enjoying it so much is that it clearly does not follow the same rules in terms of safeguards and copyright.

Kimi will happily clone MacOSX. If you ask it to help you improve another AI model, it will do it with a smile on its virtual face.

Ask Fable to do the same thing? It literally starts to perceive you as a criminal committing a war crime (like no bro, all I want to do is fine tune an open source model).

After using all three recent releases, Fable, GPT 5.6, and now Kimi, it's clear that the full power of the models has been significantly held back by the safeguard restrictions caused by last months debacle with the USG -- leading to the top models being quite literally lobotomized in some areas, which leads to subpar results as the safeguards pollute its entire thinking and problem solving abilities.

The funny part? Is that you could have predicted this outcome 2-3 years ago when you started to see the rise of Chinese EVs and smartphones compared to western alternatives.

They quite literally tried to copy the Tesla Model S and iPhone as hard as possible and then eventually it started to diverge to the point where their EVs and phones are just genuinely better (which is why we have export controls banning their EVs, because they would literally drive all US manufacturers to ZERO)

There is a very clear behavior difference in Chinese capitalism and American capitalism.

American capitalism tries to protects copyright, patents, etc (oh no, you can't download a book through LibGen, that's ILLEGAL!).

Versus Chinese capitalism actually just does not give a fuck.

"Hey you want a video gen model (Seeddance 2.5) trained on every single anime ever? And you want the main character to look exactly like Messi? Sure, here you go!"

You see what I mean? When one half of the competition is being held up by regulators and restrictions on people who don't understand the technology and the other half has a leader who quite literally today said they are going to set up AI centers around the world to help other countries onboard to their open-source AIs, this is the sort of results that you will start to get.

These models were not smart enough to have this difference in philosophy matter -- but the newest class of models is where this difference makes a big deal. If these models are finally at the point where they are smarter than 99% of humans, why would you want to use the American one who tries to impose its world view onto you versus the Chinese one who will just do what you say without asking any questions?

And this isn't a full on bullpost on Kimi, the model is clearly not as smart as Fable / GPT 5.6 on things like math and science, but it's lack of handcuffs means that it can show the world what the frontier labs are gatekeeping from you and that starts to build customer resentment and loyalty towards the East, which is probably not what the USG wants.

Interesting times. Interesting times, indeed.

HandUMI software is now open-source!

Work it harder, make it better
Do it faster, makes us stronger
🦾🤖

[Brik H. Meza @autobrik]

1/ Collect once. Retarget to any bimanual arm with parallel grippers.

I firmly believe bimanual robotic arms are the right embodiment to start adding value in the real world, and HandUMI is here to help startups accelerate deployment and researchers run more experiments.

Record data with HandUMI, no robot in the loop, replayed straight onto Agilex PiPER, OpenArm, TRLC-DK1, and I2RT YAM.

- Robot-free capture.
- Modular: swap the gripper on the arm you use and start collecting data
- LeRobot v3-compatible dataset format
- Built-in calibration + QA before conversion
- Sim replay and real teleoperation
- Apache-2.0, fully open source

Think of startup sales as a doctor/patient relationship.

If you just walked into the doctor's office and they said "here take this prescription", you wouldn't trust it at all. They don't even know what problems you have yet!

Sales is the same. You are the doctor/expert that has to ask lots of questions to understand your customer's problems before you earn the right to show how your product can help.

(shoutout @ryanRneu for teaching this to many founders)

@MsMelChen Peruvian here. The majority of us are rooting for Argentina. Argentinians do thank Peruvians for the help on the war. Peruvians thank Argentinians for our independence. Latino solidarity is nonsense, yes, and sharing language doesn't make us brothers, but sharing history does✌️

I got tired of watching my agent overthink simple problems.
