The System One harness for System One models. Run Jev and other System One models locally or directly on HarnessRouter.ai.

Evidence-backed use cases, patterns, and guidance for building with Jev, TypeSafe AI's System One model. Every claim is labeled and sourced.

Fast, typed, calibrated evaluations for LLM and agent outputs, powered by Jev — with simple, framework-agnostic Python APIs

Community Java SDK for Jev, TypeSafe's System One model: typed questions in, typed answers with calibrated probabilities out. Java 17+, Spring Boot starter (unofficial)

Observable browser stealth game: Jev makes typed guard judgments while deterministic code owns the world.

ReflexBench — open benchmark and evaluation harness for System One models and typed decision engines

AX-first computer use for AI agents on macOS with optional Jev (TypeSafe System One) semantic guards: calibrated target/input judgments before an irreversible action, decisions kept in code. Accessibility-tree targeting, window-scoped input, clipboard-safe paste, read-back verification. Ships a pip CLI, a pi package and a DeepSeek Harness plugin.

An idiomatic, type-safe Elixir port of the official TypeScript AI SDK (ai / ai-sdk) providing unified LLM integrations, streaming text and structured outputs, tool calling, and agentic workflows. Jev is their current flagship model and is the first System One model.

Dynamic latent-state control heads for LLMs: route each query by actual model capability, not task type, to answer, reason, call tools, abstain, or escalate

Self-hosted monitoring harness for System One Models

Community-maintained Go SDK for the TypeSafe AI System One evaluation API, with typed questions, fluent builders, retries, and examples.

Open schemas, recipes, templates, examples and agent tooling for Brida Reflex.

decision-first data cleaning system powered by Jev

Jev-Decision focuses on one thing missing from most current Jev-style open models: a unified decision interface across text and vision.

Code and data for evaluating Jev, a System One model, on scientific decisions and how its choices affect downstream results.

Autonomous, self-hosted AI code reviews, calibrated scoring gauges, and merge gates from any open model.
