Ant open-sources LemonDecider, a 4B decision model clocking 50.7ms
Ant just open-sourced LemonDecider, a 4B model trained on Qwen3.5 that makes direct routing, binary checks, and scoring decisions without generating wordy answers. It handles multiple decisions in a single forward pass, clocks a 50.7ms median latency to edge out Jev 1.14, and includes 1.2M training samples.
