Zeta-G1.0 Max
The cheapest, fastest, and most reliable coding agent on the planet — and the numbers below are measured, not marketing.
Cost per 1M output tokens
The frontier models that score lower also cost far more. Lower is cheaper — published list prices (hover for source).
Zeta-G1.0 Max is the fastest, most production-accurate, and the cheapest — by more than an order of magnitude over the frontier models it out-scores on ZetaBench.

Safe vibecoding
The end of vibecoding.
Vibecoding shipped fast and broke quietly — hallucinated APIs, empty catch blocks, missing auth, cross-tenant leaks. We didn’t ban it. We made it safe. Every build is gated, proven, and fail-closed.

One prompt
The whole system. Generated.
You write one sentence. Zeta returns a verified, multi-tenant, full-stack app — a real product IA (dashboards, settings, billing), realtime chat & notifications, a unique design, and a signed proof it works.
Spec
Your idea, compiled to a strict, verifiable domain.
- ISL spec — entities, behaviors, invariants
- Pre / postconditions + policies
- Stdlib auto-merge (auth, ledger, tenancy)
- Self-healing parse loop
Database
Postgres + Drizzle, multi-tenant by construction.
- Tables, FKs, indexes, enums
- Auto-injected tenant_id + owner FKs
- Row-Level Security policies
- Versioned migrations + raw DDL
- Verified double-entry money ledger
Backend
Server actions scoped to tenant + role, by default.
- withTenantRole() on every db op
- Zod validation from the spec
- Email/password + OAuth auth
- Realtime chat + notifications (SSE)
- Idempotent mutations — exactly-once
- Rate-limiting, structured logging
Frontend
A real product surface — full app IA, not a toy UI.
- Auto product IA: sidebar nav from the spec
- Dashboard · Insights · Settings · Account · Billing
- CRUD pages: list · detail · create · edit
- Skeletons, loading, empty & error states
- Page transitions + link prefetch
- Search · filter · sort · pagination
- 25 shadcn-style primitives, real a11y
Design
A distinct brand per app — never the same template.
- 16+ oklch themes × 3 design modes
- Per-app brand, font, density, skin
- Composed landing page (compile-gated)
- Responsive grids + smooth scroll
Capabilities
Bolt-ons added automatically when the idea needs them.
- Stripe billing & subscriptions
- In-app chat & activity feed
- Idempotency keys — no double-charge
- RBAC, webhooks, notifications
- File upload, full-text search
- Cron jobs, audit log, backups
Ship targets
More than a web app — a deployable system.
- gRPC proto + server/client
- Cloudflare edge workers
- Terraform AWS infra-as-code
- Runtime contract monitor
- Solidity + Foundry (on-chain ideas)
The proof
Every build carries evidence it actually works.
- Real compile gate (tsc / next build)
- Runtime cross-tenant RLS proof
- SMT-proven ledger invariants
- Security · fake-success · hallucination scans
- Signed ShipGate certificate (SHIP / NO_SHIP)
Then: live preview, ZIP, GitHub push, or one-click deploy — gated on the proof, so a build that fails verification can’t ship.
Five things Zeta does that other agents can't.
Anyone can call a frontier model. Only Zeta gates its output behind machine-checked proofs — the moat is correctness, speed and cost, not the model.
The ISL contract layer — not vibes.
Other agents emit code and hope it compiles. Zeta compiles idea → ISL → app— a typed contract of domains, invariants, events and views. Invariants are checked before ship. The spec is the source of truth, never the model's guess.
spec.isl
domain Wallet {
balance: Money >= 0
invariant never_negative:
balance >= 0
event Withdraw(amount)
requires balance >= amount
ensures balance' = balance - amount
}ShipGate is a proof gate, not a vibe check.
A generated app must pass every gate — fake-success-UI detector, firewall-enforce, RLS-proof, tsc exit 0 — or it never ships. Most agents fail-open: they produce broken code and call it done. Zeta blocks, and attaches the proof bundle.

Solidity that's proven, then signed.
/api/contract/prove runs forge build, tests, slither and Halmos symbolic execution. Vulnerable → REFUTED / NO_SHIP. Safe → PROVEN + signed certificate, keccak-anchored on-chain. Other agents “review” contracts; Zeta proves conservation invariants and refuses to certify what it can't.

End-to-end runnable repo, live-booted.
idea → ISL → codegen → next build exit 0 → boots a real app in isolated Postgres → iframes the live preview. Real scrypt auth, RLS tables, BYO-key Stripe, a working money loop. Not a snippet — a bootable product, proven.

It self-heals its own output.
Zeta reads its own gate failures, patches, and re-runs until green — bounded attempts, no infinite spin. Imported projects: Gemini installs, builds and debugs to green, then Zeta takes over. A closed correctness loop, not one-shot generation.

Fail-closed
It refuses to ship broken code.
Anyone can demo AI writing code that looks finished. Plant a real flaw — missing auth, a leaked key, RLS switched off — and the gate returns NO_SHIP. A build that can’t prove itself can’t leave the door.
Planted: a mutation with no auth, a hardcoded key, RLS left off.
- Compiles (tsc + next build)
- Mutations require authentication
- Auth guard present in emitted code
- Row-level security proven at runtime
- No hardcoded secrets or dangerous sinks
- Inputs validated with zod
Blocked. Download, deploy and the ship button stay locked.
Self-healed, re-gated. Every claim now carries evidence.
- Compiles (tsc + next build)
- Mutations require authentication
- Row-level security proven at runtime
- No hardcoded secrets or dangerous sinks
- Generated test suite executes green
- Declared properties proven by symbolic exec
Cleared. Now you can preview, push, or deploy.
Same prompt, two outcomes — the only difference is whether the evidence checks out. The gate is fail-closed: degraded tooling or an unproven claim counts as NO_SHIP, never a false green.
Formal proof · not a static scan
Prove your contract. Sign the proof.
Upload Solidity and get a signed, bytecode-bound certificate — Foundry + Halmos symbolic execution with cvc5, non-vacuity enforced. Degraded tooling never returns a false green. Build web3 apps on the demo; prove contracts here.
