12B open model Chon-1.0 tops JevBench; slow thinking triggers 10s rule

xoai · x · 2026-10-22

Chon-1.0-12B by Ninh Nguyen takes the new #1 spot among open models on JevBench with a capability score of 85.3, ahead of a 31B model at 82.5. However, it tends to "think" when unsure — its slowest 5% of decisions take 33 seconds. In response, a new rule is coming: decisions taking more than 10 seconds will count as failed. The author also submitted re-runs for Chon-1.0-12B and Chon-1.0-E4B, plus a new evaluation request for Chon-1.0-12B-Fast.
