An independent, Jev-inspired System One engine written in C# and .NET 10: a pinned Laya/mmBERT checkpoint runs through pure C# CPU and CUDA kernels with Native AOT, returning typed Choice, Score and Boolean decisions to .NET applications. Probabilities are explicitly uncalibrated.
Jev Models & Reimplementations#community#dotnet#inference
Unofficial .NET port of the JavaScript SDK covering SystemOne noul, choice and score questions with env-based config, retries and typed errors.
Jev Demos & Experiments#community#github

.NET 10 client plus MCP server for the Jev evaluation API, covering noul, choice, and score questions with typed answers, probability distributions, and confidence values.
Jev Tools & CLIs#community#github
1GitHub stars
Dependency-free .NET client for Jev targeting net8.0, sending state plus Choice, Score, and Noul questions and returning typed answers with confidence for threshold gating.
Jev Repos & SDKs#community#github
1GitHub stars
Independent .NET client for the System One API with typed noul, choice, and score questions, DependencyInjection integration, cached model discovery, local validation, and typed errors.
Jev Repos & SDKs#community#github
MIT-licensed Microsoft.Extensions.AI providers for Anthropic Claude and TypeSafe Jev, plus a SupportDesk console sample wiring triage, drafting, and review together.

.NET 10 client for the TypeSafe evaluation API that evaluates a state against typed questions and returns structured answers.
Jev Benchmarks & Evaluations#community#github
3GitHub stars
.NET port of the JavaScript SDK that batches Choice, Score, and Noul questions in one call, resolved by explicit options, environment, then defaults.
Jev Repos & SDKs#community#awesomejev#catalog-import
4GitHub stars
.NET client for System One where you declare choice, score, and yes-or-no questions in C# and get typed answers with probabilities and confidence back, installable as one NuGet package.
Jev Repos & SDKs#community#awesomejev#catalog-import
3GitHub stars
Unofficial .NET 10 HTTP client for TypeSafe Jev and the Jev-compatible local Laya server that posts the shared /v1/systemone body and returns typed Choice, Score and Noul answers, with no runtime package dependencies.
Jev Repos & SDKs#community#jevbest#catalog-import
3GitHub stars
A community-maintained .NET 10 client for the official TypeSafe Jev API, covering the Choice, Score and Noul primitives with Microsoft.Extensions.AI composition, model discovery and ten runnable samples. Released as tentative 0.6.0 with live compatibility unverified.
Jev Repos & SDKs#community#awesomejev#catalog-import
3GitHub stars
A C# client for the TypeSafe System One API with one dependency, a faithful port of the official Python SDK's behaviour, and typed answers bound to properties by name.
Jev Repos & SDKs#community#awesomejev#catalog-import
2GitHub stars
A .NET 10 and React 19 support-ticket triage application: one batched Jev call yields five typed decisions, a deterministic rule engine makes the final call, and every field reports whether the model or a rule decided it. Accepts Persian and English.
Jev Tools & CLIs#community#jevbest#catalog-import
1GitHub stars
A pre-release .NET decision library that keeps the domain in a dependency-free Core assembly and reaches Jev through a pluggable provider, so changing vendors does not mean rewriting your application model.
Jev Repos & SDKs#community#jevbest#catalog-import
1GitHub stars
C# client for Jev, TypeSafe AI's System One model. Typed Noul, Choice and Score questions go out with one state in a single round trip and come back with a value, a probability distribution and a confidence number. Choice questions can be built from an enum, so the compiler finds the switch branch you forgot.
Jev Repos & SDKs#community#awesomejev#catalog-import
2GitHub stars
A Windows MCP server for Codex and Claude Code that runs bounded UI Automation tasks and durable multi-source research jobs, letting Jev choose only among actions deterministic code created, and returns a compact typed trace instead of a stream of screenshots.
