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.

Muyukani Kizito says JarvisCore uses Jev in its agent runtime for RAG classification and ranking, model routing, subagent routing, and agent decisions.
