I built non-autoregressive decision models with RL a year ago(laya.convaiinnovations.com)

tl;dr: The author claims to have pioneered non-autoregressive, RL-trained decision models a year before TypeSafe AI's Jev launch, and is releasing Laya, an open-source Apache 2.0 alternative built on bidirectional encoders (ModernBERT/mmBERT). Laya outputs calibrated probabilities for choice/score/boolean schema questions in ~33ms (7.8x faster than Jev), supports 100+ languages via a Unicode-based router, and reportedly beats Jev on accuracy and calibration for most benchmarks—though it degrades on choice sets over 20 options and requires fine-tuning for strong task performance.
HN Discussion:
  • ↓Author failed at marketing/branding, which matters more than the underlying technology
  • ↑Jev's hype-laden language was off-putting and the tech isn't a real breakthrough, validating the author's frustration
  • ↓Prior work like GLiNER predates the author's claim, undermining the pioneering narrative
  • ↓Author is bitter and juvenile; Jev built a product while author only published research
  • ↓Laya has significant technical limitations (tiny context, requires fine-tuning, small model) making the comparison to Jev misleading
