Why the edge:
- Reliability, Decider +50: Decider 90 (Scored on the local-package checklist, since Decider is open weights the owner runs, as for Kev and Strands Decider.); Gemini Decision 1 40 (Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint.)
- Payments & pricing, Decider +30: Decider 90 (Free Apache-2.0 software with nothing to buy, so 20 + 20 + 20 for pricing, free use and no sign-up, by the self-hosted rule.); Gemini Decision 1 60 (Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint.)
- Transparency & trust, Gemini Decision 1 +18: Decider 52 (Apache-2.0 for the code and model repositories, with the training code, data builders, teacher data and per-stage measurements published.); Gemini Decision 1 70 (Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint.)
- Security & auth, Gemini Decision 1 +7: Decider 38 (Read as software you run.); Gemini Decision 1 45 (Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint.)
- Agent ergonomics, Gemini Decision 1 +5: Decider 80 (Read as an API an agent calls for a decision, as for the other decision models.); Gemini Decision 1 85 (Read on the tool lines, as the other decision-model listings are.)
