Jev-systemOne-model
1GitHub stars
A GitHub repository whose only published description is its name: Jev-systemOne-model. It was created and pushed on 2026-09-29, has one star, and lists neither a language nor a license; the digest captured no README, so its contents cannot be verified.
Jev Repos & SDKs#community#github#unverified
CommunityRahulKumarsingh2001/Jev-systemOne-model
System One Native
1GitHub stars
A Python decision engine that runs Choice, Noul and Score questions on Gemini's free tier, Groq, OpenAI or a local Ollama server with local response validation. The README calls it a drop-in alternative to Jev and ships agent skill and plugin installs.

CommunityRodrigoAlbe/system-onePython
TIEG.SystemOne.LLamaSharp
1GitHub stars
A .NET extension for LLamaSharp implementing a System One pattern: it extracts raw logits from a single parallel batch pass to classify in under 100 ms, bypassing autoregressive generation and reserving VRAM for larger fallback models.

Jev
0GitHub stars
A GitHub repository simply named Jev, created and pushed on 2026-10-02 with 0 stars, 0 forks, and no listed language, license or description; the sweep captured no README, so what it contains and how it relates to TypeSafe's model cannot be confirmed.

JEV
0GitHub stars
A GitHub repository named JEV, created and pushed on 2026-10-08 with 0 stars, 0 forks, and no listed language, license or description; the sweep captured no README, so its contents and any link to TypeSafe's Jev model remain unverified.
