Jev Benchmarks for Review Pipelines

Niels Bantilan benchmarked Jev against a “System 2” approach for customer support, code review, and legal contract review. He reports Jev was up to x2.6 faster and at least x10 cheaper, with no loss in quality.

🤔 Where do #Jev and other "Decision Models" fit into your current agentic or non-agentic pipelines? The short answer: anywhere you might have LLM calls with a #pydantic model or json schema to type-cast your raw data into structured categories, Likert-scale numerical scores, or true/false decisions. I ran three benchmarks with @flyteorg on https://t.co/WczbNQoVLn in the context of three use cases: - Customer support - Code review - Legal contract review In all three cases, using Jev was faster (up to x2.6) and cheaper (at least x10) with no loss in quality compared to using a "System 2"

Bantilan ran the benchmarks with Flyte. He describes decision models as suitable for LLM calls that turn raw data into structured categories, Likert-scale scores, or true/false decisions.
