jev-demo
A customer-service routing demo that batches Jev questions before following the resulting route.
Assesses classification levels, human-handoff intent and frustration, with low-confidence escalation.
↳ Combines routing and human handoff while leaving response generation to the application.
hugo-alves
jev-router-playground
A model-routing playground where Jev picks a candidate and users compare the resulting answers.

can1357
oh-my-pi
Oh My Pi includes an optional TypeSafe judgment provider for bounded decisions in coding-agent workflows.
Sends agent state and typed questions to Jev and parses structured answers.
↳ Adds a replaceable judgment provider to existing agent workflows.
BerriAI
litellm
LiteLLM can use Jev to classify requests for its complexity-based model router.
Maps requests to configured complexity classes that drive backend routing.
↳ Makes the complexity judgment behind routing inspectable.
kunchenguid
firstmate
Firstmate can optionally use Jev to match task briefs to dispatch rules before local policy chooses an Agent configuration.
Sends the task brief and candidate rules to Jev, then resolves execution profiles with confidence and local conditions.
↳ Separates semantic matching from the final dispatch policy.
openchamber
openchamber
OpenChamber’s optional automatic model router uses Jev to classify a message before selecting a configured model and reasoning level.
Jev selects a task category; local category mappings determine the model configuration.
↳ Keeps routing categories and their model assignments explicit.
bastani-inc
atomic
An optional Jev decision backend in the Atomic coding Agent for bounded structured choices such as routing.
Sends predefined questions to Jev and decodes answers for callers; regular models still generate code.
↳ Separates structured decisions from text-generation interfaces.
WrongStack
WrongStack
An optional Jev dispatch classifier for choosing among WrongStack specialist Agents.
Jev evaluates the task against eligible specialists; local dispatch rules use the result.
↳ Makes specialist selection a configurable step in an existing coding Agent.
notque
vexjoy-agent
An optional Jev routing path that matches VexJoy requests to specialist Agents, skills and workflows.
After deterministic routing guards, Jev judges the remaining candidates and required workflow components.
↳ Keeps repeatable routing rules and model-selected candidates in separate stages.
kitze
skillbox
A self-hosted, versioned Agent skills library with optional Jev recommendations.
Jev scores task relevance among skills the client is allowed to access.
↳ Suggests relevant skills while retaining the library’s client access scope.
yusukebe
hono-jev-router
An experimental semantic HTTP router for Hono using natural-language route descriptions.
Jev scores request-to-description matches; code selects the first route above its threshold.
↳ Explores semantic routing; the author explicitly warns against using it for authentication or authorization.
BillionsBobby
JevRouter
Routes among models, subagents, skills, MCP tools and CLIs using a shared candidate set.
Jev makes a Choice; the router separately checks availability, permissions, risk and confirmation policy.
↳ Records model choices separately from execution policy.
maker-KK
todo-jev
A task-routing experiment combining skill conditions and environment checks to suggest rules, skills or a large model.
Jev classifies requests and matches skills, with heuristic fallback when unavailable.
↳ Classification and recommendations are implemented; execution handlers still return examples and need real integrations.
davila7
jev-model-router
A community Claude Code Templates mod that uses Jev to suggest subagent models and reasoning levels.
Evaluates task tier, reasoning needs and production risk; local policy maps results to invocation settings.
↳ Makes routing rules and per-request choices explicit and configurable.
wundercorp
loki
Loki optionally adds Jev typed-judgment tools and routes a new session to a model within the selected gateway.
Assesses the first task’s capability needs; local policy chooses a same-gateway model and keeps the route sticky.
↳ Makes model routing explicit while retaining the selected route for the session.
DECRUX9812
typesafe-skill-router
An opt-in Hermes Agent plugin that asks Jev to suggest one relevant skill before a model call.
Compares the request with the skill roster; inserts a suggestion only when suitable and abstains on failure.
↳ Adds a targeted skill hint that the Agent can still ignore.
gargpratyush
jev-router
A Claude Code and CLI proxy that asks Jev to score task complexity and pick a model from the account’s available set.
Scores task, reasoning, and tool complexity, then chooses among the exact models the account can run; failures keep the current model.
↳ Makes model choice an inspectable closed-set decision, and never blocks a prompt when Jev is down.
aaronshaf
opencode-jev-orchestrator
An OpenCode orchestrator that keeps a cheap sticky parent model and, when Jev flags a hard turn, escalates through a child subagent.
Scores task, reasoning, and tool complexity, then chooses fast / balanced / strong / long; local policy stays, escalates, or fans out.
↳ Keeps a cheap sticky parent model and opens a stronger child only when Jev flags a hard turn.
iamvatsalpatel
tiershift
Policy-driven model routing framework routing every LLM call to the cheapest capable tier in ~180 ms via TypeSafe Jev.
Uses declarative YAML policies evaluated by Jev discrete classification without requiring pre-collected training data.
↳ Provides unified TypeScript and Python interfaces to minimize inference spend with minimal routing overhead.
FirasSX914
Janus
Framework for measuring when to employ Jev versus generative LLMs on proprietary datasets, routing queries based on measured benchmarks.
Benchmarks Jev response accuracy and latency via a TypeSafe provider integration, deriving empirical routing policies.
↳ Replaces intuition with empirical data when adopting discrete decision models, optimizing overall cost while preserving task success.
kuldeepsinh19
jev-decision-gateway
A gateway that asks Jev continue / tool / verify questions and invokes a generative LLM only when policy says generation is needed.
TypeSafeClient.systemOne answers policy questions; the adapter then decides whether a generative model runs.
↳ Places expensive generation behind a Jev gate. Author-reported call savings were not retested here.
prismhq
jev-router
An open-source LLM router built on LiteLLM and Jev: dynamically routes requests based on task complexity and context.
Evaluates reasoning requirements of input prompts via single forward pass, delegating dispatch to LiteLLM.

mejiasd3v
pi-jev-router
Automatic model router for Pi coding assistant: integrates Jev via Vercel AI Gateway to dispatch tasks efficiently.
Quickly estimates task complexity from code context and user query, routing between SLMs and frontier models.
↳ Brings out-of-the-box intelligent cost-saving routing directly into the Pi terminal workflow.
rajdhakad9826
jev-router
Cost-aware LLM router that picks the cheapest model capable of handling a query, using TypeSafe's Jev for fast classification instead of an LLM call.
Jev returns a structured decision for the local program; consult the source for the exact decision policy.
↳ Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.
