Super exciting work from my friend @RyanBoldi! From an HCI POV, I’m especially excited about how RL on multiple objectives might make models more socially intelligent while avoiding pitfalls of optimizing on one narrow objective (e.g., sycophancy from RLHF)

[Ryan Bahlous-Boldi @RyanBoldi]

Your RL post-training may be sabotaging your LLM’s test-time scaling!

Conventional RL pretends that you can collapse all reward signals *upfront* into a single *scalar reward*.
We introduce Vector Policy Optimization (VPO), which natively maximizes *vector-valued* rewards, boosting test time search performance, even on the original scalar.

Give it a read and let me know what you think! https://t.co/INfmgRG3PL

Sycophancy, disempowerment, homogenization of thought: lots to be grim about for what AI is doing to us, the collapse of our subjectivity into a machine "objectivity". But a lot of AI's value seems to come precisely from scaling this objectivity. How do we make sense of this?

[Andre Ye @andreiskiii]

In the picture I lay out, we need work both *within* norms and work *on* norms. We've already thought a lot about how AI can help us work *within* norms, since that objective was more easily definable. There is more to be done on AI that helps us work *on* norms.

“Should I fear death?” Ask an LLM and you get one answer or a big bag, but little visibility into the decisions and assumptions that produced them. We built the "conceptual multiverse": a system that makes those decisions transparent and intervenable. https://t.co/oQlWs0KFHu

Thank you so much to my incredible collaborators @JennyHuang99, @upcycledwords, Rose Novick, @ta_broderick, and @mitchellgordon!

[Andre Ye @andreiskiii]

Check this blogpost out! I think this is a really exciting and important direction to be thinking about.

[jenny huang @JennyHuang99]

recently, i’ve been thinking about ways to design ai systems to be more compatible with slow thinking 🐌.

There's been a lot of excitement about pluralistic value alignment 🌈 — AI that reflects the full range of human perspectives

But no formal way to benchmark whether we're actually making progress. 🤔
