Hassan's Tev1 0.8B runs on his Mac at about 50ms end to end

Hassan trained Tev1 0.8B, a smaller sibling to the tev1-4B classifier he put out earlier, and filmed it classifying tasks locally through Ollama. He put end to end latency at roughly 50ms and said the video is not sped up. Weights and benchmarks are promised but not out yet.

Someone measured it

TypeSafe posts Deel's numbers on six Jev classification tasks

TypeSafe AI published what Deel measured across six pick-from-a-known-set tasks, including matching repeat analytics questions, blocking PII requests and sorting expenses into about 55 categories. Repeat-question matching went from 70% to 97%, expense categorization from 50% to 86% against human reviewers, and escalation caught the same cases with fewer false alarms.

He describes it as an experiment, with no accuracy numbers attached.
