Models & Usage
Most AI-tooling plans meter you tightly because the model underneath is expensive. A plan built on a single first-party frontier API — a Claude Pro seat, say — burns through its allowance fast, because every token is billed at premium first-party rates. Sigilix is built differently. We run a roster of cheap, highly reliable open and frontier models — the kind that are now industry-standard and dependable for production code work — so our cost base per review is a fraction of a single-vendor stack. That difference is passed straight to you: far more headroom for the same money.The point isn’t “cheap models, cheaper output.” Every finding still clears the full believability pipeline — evidence, provenance, refute/execute, proof-tier receipts. Lower cost buys you more usage, not lower standards.
The models we run
You can pick the model that fits your work and your usage. The roster includes industry-standard open and frontier models such as:DeepSeek V4
Strong reasoning for logic and architecture work.
Kimi K2.7
High-quality, high-throughput code reasoning.
MiniMax M3
Reliable general-purpose code understanding.
GLM 5.2
Capable, cost-efficient coverage across roles.
On the hosted PR ensemble, each specialist — Metis (logic), Argus (security), Iris (performance), Eunomia (tests), unified by Harmonia — runs the model tuned to its role, behind cross-provider fallback so one provider’s outage can’t silence a specialist. See The Ensemble.
Pick your own model
You’re not locked to one choice. Select the model that matches the work and the budget you want to spend, and change it as your needs change. On the CLI and Deep-Research Chat, you can also bring your own model — Codex CLI, Claude Code, or your own SDK and provider keys — and pay that provider directly. Your model still fetches Sigilix’s verified earned-context layer, so it inherits the precision without re-deriving your repo.Generous usage windows
Because the cost base is low, included usage is generous — meaningfully higher than a comparable OpenAI- or Claude-based plan for the same price.Per-seat base + metered usage
Each tier is a per-seat base plus metered usage for review volume and agent tokens. No fixed PR windows — you pay for your team plus the work Sigilix actually does.
Pick the model that fits
Run a cheaper model for routine volume, or a heavier one where it matters. The choice is yours, per your usage.
