You don’t need frontier lab resources for frontier lab automated LLM evaluation.
To prove this, we’re open-sourcing j1-nano and j1-micro: two absurdly tiny (600M & 1.7B parameters) but mighty reward models competitive with orders-of-magnitude larger peers.
j1-nano and j1-micro
First came pre-training scaling; then came inference-time scaling.
Now comes judge-time scaling.
Despite progress in AI through scaled inference-time compute, AI remains unreliable in open-ended, non-verifiable domains. The key limitation is not generation—it is evaluation.
i've been entirely consumed these past few weeks by the LLM-as-a-judge research agenda.
there's lots of great work, but there's also lots of noise, confusion, and redundancy in the literature. i’ve started curating the highest-quality reads here:
super excited to share what we've been cooking up at @haizelabs🕊️🕊️
we are now in the era of grossly excessive AI hype and demoware.
but it is high time to recalibrate and revisit the difficult, unsexy, underlying problem that everybody is avoiding -- the AI reliability and
Today is a bad, bad day to be a language model.
Today, we announce the Haize Labs manifesto.

We showcase below one particular application of haizing: jailbreaking the
