Frequently asked questions
- What does Sigilix announce here?
- Model releases and product notes for the Boreas, Pyroeis, Astraeus, and Phanes model line, plus updates to the tools around them. Each announcement explains what a model is tuned for rather than presenting it as a general-purpose leaderboard win.
- Are Sigilix models ranked as beating other models?
- No. Benchmark figures are shown against same-tier peers and described as competitive within that tier, with the source rows disclosed. The models are capability tiers for CLI and agent work, kept separate from the role-specialist ensemble that powers PR review.
- Why is Phanes announced but not available?
- Phanes stays on a private evaluation path until its memory guardrails behave like product infrastructure: visible citations, auditable provenance, rejection of stale context, and confirmation on high-impact actions. The announcement is about that release bar, not a launch.
