Decomposed prompts boost Jev phishing accuracy to 95%
Early evaluation benchmarks demonstrate that decomposing a phishing email assessment into five narrow, specific questions increases TypeSafe Jev's classification accuracy from 62.6% to 95% on the exact same emails and model. Rather than generating conversational text token-by-token, Jev evaluates unstructured inputs against predefined questions in a single parallel pass to return structured types with calibrated probabilities in 70–500ms, making high-accuracy automated triage both faster and significantly cheaper than traditional LLM pipelines.
Broad single-shot prompting is inadequate for enterprise classification; decomposing tasks into atomic, structured evaluations is essential for production-grade reliability.
* Query decomposition dramatically outperforms broad prompts: Breaking down the evaluation criteria into five focused sub-questions yields a 32.4 percentage point accuracy boost without altering the underlying model or data.
* Shift toward non-generative "System 1" architectures: Conventional LLMs waste compute and introduce schema-parsing overhead, whereas typed parallel evaluators deliver deterministic, low-latency decisions for backend automation.
* Production rigor versus timeline demo hype: While Jev's launch sparked widespread single-prompt demos across social media, real-world utility in security pipelines relies on disciplined multi-query orchestration.
