Jev prioritizes System 1 reasoning for ultra-fast classification, targeting latency bottlenecks in agent workflows rather than chain-of-thou
Jev abandons text generation to become a pure decision engine with sub-200ms latency and negligible costs.
Ex-OpenAI researcher Diogo Almeida launches Jev System 1, claiming it is 200x faster and 400x cheaper than standard LLMs by stripping out te
Jev excels at rigid schema-based routing but fails on open-ended generation or complex reasoning.
Together AI fine-tunes Qwen3.5 4B into a Jev-style classifier for $17 in 25 minutes.
