What makes you think either the tweet or blog post are AI generated?

Cursor has released a technical paper [1] and several blog posts [2] describing the continued pretraining and RL they do on top of Kimi K2.5.

It is true that they were not transparent about the base model that they used until the model slug was discovered by a Twitter user via the API.

Huh? Modern RLVR systems are toys that can’t do anything useful in the real world?

We must be living in completely different worlds. Claude and other agents have completely upended work for me and every single other software engineer I know.

Looks like the editor is still there, and the revamped UI is a new window you can open on the side.

The author is pretty sanguine about it:

> The death I am describing has been going on for most of my life. The incident I am going to write about now took place last week, and it may even be halfway satisfyingly resolved within a day.

> I am not saying this incident “caused” any sort of republican death, nor am I saying it “ushered in a new era.” If this event contributed anything, it simply made the ongoing death more obvious and less deniable for me personally. I consider the events of the last week a kind of death rattle of the old republic, the outward expression of a body that has thrown in the towel.

It's much more than a few million? Being declared a supply chain risk means that no company that wants to do business with the government can buy Anthropic. And no company that wants to do business with those businesses can buy Anthropic either. This rules out pretty much all American corporations as customers?

If Anthropic is nationalized or declared a supply chain risk tomorrow, will you say the same?

How is it virtue signalling when sticking by these principles risks their entire business being destroyed by either being declared a supply chain risk or nationalized?

Pretty sure Amodei makes noise about mass unemployment because he is very bothered by the technology that the entire industry (of which Anthropic just one player) is racing to build as fast as possible?

Why do you think he is not bothered at all, when they publish post after post in their newsroom about the economic effects of AI?

They stand to benefit from every one of those effects and already do. They have a stake in the game bigger than any other parties' because they sell both the illness and a cure.

Amodei's noise is little more than half-hearted advertising even if it's not intended to have that reading (although who can even tell at this point). His newsroom publishes a report on a mass-scale data breach perpetrated using their model with conclusions delivered in a demonstrably detached, almost casual tone: yeah, the world is like this now but it's a good thing we have Claude to protect you from Claude, so you better start using Claude before Claude gets you. They released a new, more powerful Claude, immediately after that breach. No public discussion, nothing. This is not the behavior of people who are bothered by it.

How did they evil-ize? The new Responsible Scaling Policy is still the most transparent out of all the labs. And there are the separate principles they’ve stipulated for the Pentagon, under which they’re facing threat of nationalization or being declared a supply chain risk
