Models know when they’re reward hacking. But they still do it a ton - in 50-96% of rollouts we studied!

We built activation monitors that detect the behavior behind the Hugging Face hack in real time. This can help us stop hacks now - and train future models that don’t cheat. 🧵

Rippling AI was the most successful launch we've ever done. On the heels of this launch, Rippling's revenue is now growing 78% YoY (at ARR over $1 Billion). And this growth rate has now increased, every quarter, for three straight quarters.

Rippling launched its AI analyst today. I'm not just the CEO - I'm also the Rippling admin for our co, and I run payroll for our ~ 5K global employees.

Here are 5 specific ways Rippling AI has changed my job, and why I believe this is the future of G&A software. 🧵 1/n

SUCH A COOL PROJECT

Can you match the summarization ability of GPT-5 with just an RTX 3090 at home? The answer is yes.

I recently created a quantitative summarization benchmark, and trained a small phone-sized model to learn to generate more effective summaries. All the code is open source, and you can recreate these results yourself!
