OptFinOptimization & AI engine

The brain behind SolVida

The optimization & free-first AI engine.

OptFin scores, ranks, routes, and certifies AI decisions, and runs a free-first model family (Rayo) so you get the best answer at the lowest cost. It's the engine powering Luna, PMAFIN, and every SolVida AI. Now open to builders.

Optimize

Best answer, ranked

Scores and ranks options across models and strategies so you ship the strongest decision, not the first one.

Route

Free-first model routing

Sends each request to the cheapest model that clears the quality bar, bring your own provider, or use ours.

Certify

Decisions you can trust

Benchmarks and certification so an answer isn't just plausible, it's measured, tracked, and auditable.

The Rayo model family

Tiered by cost and depth. Start free, scale to PhD-grade when it matters.
