Jev guides and FAQs

Understand Jev's state, Choice, Score and Noul outputs, how they differ from chat, and which decisions belong in ordinary code.

Understand what a decision engine does, how Jev's Choice, Score and Noul outputs differ from rules and chat models, and how to evaluate one.

Find official recipes and community demos, then choose a Jev example that matches the decision you need to build and evaluate.

Compare the official Jev playground with community demos and runnable samples by task, evidence, provider and the next step to test.

Use typed decisions for semantic SQL and graph navigation. Plan permissions, caching, evidence and review before adding model calls to data pipelines.

Build a Jev search workflow: retrieve candidates, check relevance and answerability, preserve provenance, and keep unsupported RAG answers out.

Design exclusive categories, independent tags and a review queue. Start with a typed Python example and test unreadable, ambiguous and hostile documents.

Design model-assisted risk checks with deterministic permission boundaries, review paths and failure handling. Compare the different Jev Guard projects.

Find the official SDKs and request shape, distinguish OpenRouter Decisions from chat routing, and check community Java, Rust and adapter compatibility.

Choose Jev paper tools for discovery, PDF feedback, claim marking or systematic screening, with clear boundaries for retrieval and review.

Choose between an agent skill, model router, permission hook and context tool. See what Jev does inside a coding agent and what the LLM still does.

Use Jev inside Hermes Agent for skill selection, model routing and command approvals. See the documented projects, setup steps and failure modes.

Wire Jev into the Pi coding agent: tool-call gates, auto mode, model routers and context selection, with the projects that document each job.

Compare context pruning projects, decide what must survive compaction, and evaluate token savings against the agent's ability to finish its task.

See how text-only Jev fits browser, voice, game and robot loops, and why community visual models need separate evidence and hardware checks.

Find Jarvis, office assistants, Mac bridges, call visualizers and browser extensions. Compare client permissions and which model actually writes replies.

Call Jev's typed Decisions API through OpenRouter, separate it from jev-router chat routing, and handle authentication, versions and errors.

See how the community Paperclip Jev plugin routes issues and proposes browser actions, how to install it, and where human approval stays.

Compare Laya, LEV, Kev and other independent decision tools by weights, protocol, hardware and evaluation, without confusing them with Jev.

Read benchmarks without mixing datasets or model versions. Measure accuracy, calibration, review coverage, latency and cost on your own workload.

Understand Jev Trader's decision loop and how to evaluate trading experiments with independent risk limits, execution records and realistic test conditions.

Compare JEV-MLX, Jev Visual and OneJev by hardware, modality, protocol and evaluation limits before choosing local Jev-like inference.
