A Ruby gem for asking Jev and other decision models typed questions, with no dependencies beyond the standard library.
@obieDecision models like Jev answer typed questions about some text with calibrated probabilities instead of writing text. This gem gives Ruby apps one client for them.
It uses OpenRouter by default, with TypeSafe's own API as a second option and room for more providers as they appear. Nothing to install beyond the gem itself.
A single interface across dozens of AI providers, with a calibrated decide call powered by Jev for the routing and gating choices text generation was never meant to make.
Jev
TypeScript
Node.jsConnects Claude Code, Claude Desktop, Codex, Hermes and pi to Jev, so an agent gets back a typed judgment with a real probability instead of prose it has to parse.
Jev
GoA type-safe Scala client for Jev, added as a new module to sttp-ai, SoftwareMill's existing Scala toolkit for OpenAI, Claude and Gemini.
Jev
ScalaA C++20 library that turns application context straight into typed enums, boolean decisions and scores, with a local or remote Jev-style backend behind one API.
Jev
C++
CUDATurns any open-weight LLM into a Jev-style decision model, reading typed choices and calibrated probabilities straight from its logits or hidden states.
Jev
Python
vLLMTrims long command output with Jev before Claude Code reads it, so later turns carry less noise.
