Everyone trains RL by spending compute where the model is uncertain.

That's wrong.

Spend it where it actually teaches the model something. Here's what that looks like

Our Northstar model is finding a new home on Mac mini. Interested in seeing what people build with this.

This is the year of computer use – and so we're hosting a hackathon with @sfcompute, @nvidia and @usekernel on computer use, open source models & evals,

Frontier performance, at a fraction of the cost. Northstar is built for real-world workflows — and strong vision capabilities enable impact across real apps.

@albrgr @davidshor @dwarkesh_sp Last time I looked into this Anthropic overshot a lot and OpenAI were mostly in range, slightly above.

@magnushambleton Following up on this, it's happening in the US! Flock is currently solving 10% of reported crime in the US.

@antirez Note, that it's not merged.

@copyconstruct AI coding tools can't solve these problems.
