Automated README summary
Automatically summarized from the README on 18 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
S1 Studio is an open-source web workbench for testing structured decision models that speak the /v1/systemone protocol, including TypeSafe AI jev, Cloudflare clef, Ollama clef, and custom endpoints. It visualizes Choice, Score, and Noul probability diagnostics for developers.
How it uses Jev
Users pick the TypeSafe AI endpoint (jev-latest) as a profile and build up to 64 typed questions (choice, score, noul) against a text or JSON state, optionally with images. S1 Studio sends the request and renders calibrated probabilities as diagnostic cards, threshold sliders, and bimodal warnings; it also exports SDK code.
Primitives:choicescorenoul
Technique worth stealing
Treating model output as calibrated probabilities and diagnosing them visually (threshold simulation, confidence, bimodal detection) instead of reading generated text.
Try it
Open https://s1-studio.miniasp.com/ or run make install then make dev locally.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
