Together launched the experimental tev1-4B-experimental classifier, fine-tuned from Qwen3.5 4B with a Jev-like approach, available on Together serverless at $0.042/M input and $0/M output. The data recipe and a fine-tuning tutorial are also public — Tev1 reportedly cost only $17 to train.

N8Programs cautions that a Jev-like classifier label doesn't imply weak capability: it dominates on a wide range of benchmarks, sometimes by 20 percentage points.
