RL with Verifiable Rewards, Where the Verifier Is a Wet Lab

Lila Sciences treats the wet lab as a verifier in an RL loop, generating 10 trillion experimental tokens to train a single generalist model across biology, chemistry, and materials. The lab becomes a data center, not a product factory — and the counterintuitive result is that breadth across sciences yields better model depth than narrow specialization.

PARE: A Stateful Benchmark for Proactive AI Assistants

This work exposes a core blind spot in proactive AI assistant research: benchmarks that flatten apps into stateless APIs can't test real-world anticipation and timing. The proposed PARE framework models applications as finite state machines, enabling stateful user simulation and a 143-task benchmark across communication, productivity, and scheduling domains.

The Harness Is the New Battleground for Enterprise AI Data Trust

The core tension exposed here is that enterprise AI adoption forces customers to hand over their proprietary knowledge—not just pay for compute—because every user query generates a trajectory that can be fed back into the model to improve it. Unlike SaaS, where customer data stayed in isolated databases, AI vendors can legally and technically absorb that data into their own intellectual property. Satya Nadella and Alex Karp both warned publicly that companies are paying for intelligence twice: once with money, and again with the trade secrets they must reveal.

Meta’s Mosseri: AI token budgets may be capped per engineer in 1-2 years

Adam Mosseri predicts that within a year or two, Meta will need to cap AI token budgets per engineer because the burn rate could equal their salary. The article details how companies like Meta, Uber, and Microsoft are already wrestling with runaway AI costs, forcing a shift from unlimited experimentation to managed resource allocation.
