Onyx — the operator that builds, markets, and runs the whole business

What it does

• The whole business, one prompt. A single objective can drive a working app, a landing page, a promo video, a week of scheduled multi-platform posts, and a spoken recap of what shipped — one run no single-purpose tool can span.
• You own what it makes. Competitors rent you your own output and keep you inside their host and their meter. What Onyx produces is yours — portable and under your control.
• A brain that already knows you. Tephra sits underneath on every prompt, so Onyx starts with your brand rules, your past decisions, and your context already loaded, instead of a blank slate every time.
• A fleet, not a single model. Onyx fans each objective across specialist sub-agents running concurrently on many models, then merges the result — top-tier quality at a fraction of the cost by using the right model for each part.
• Real tool-use, real work. It reads the live web, writes and edits files, executes code, and drives long multi-step tasks to completion — not a chat that describes the work, the operator that does it.
• Studio-grade video, built in. Onyx generates brand-consistent, unwatermarked video on real GPU and can schedule it out in the same run. Video is not a separate subscription.

How to get Onyx

Onyx is part of VIP — $39/mo at the member rate through the Obsidian Metrics community, or $59/mo direct from the website. Or buy the seat outright for $599 once: perpetual access with no subscription. Usage is metered either way; the $599 seat includes approximately $300 of usage credit, and once that credit is spent you top up to keep using it. The seat itself does not expire — the credit gets used up. See membership and pricing.

Frequently asked questions

What is Onyx?

Onyx is the operator — a whole business team in one place that you talk to like a CEO. You set an objective in plain language and a fleet of specialist sub-agents, running concurrently across many models and drawing on a deep capability library, produces the real deliverable and reports back while your conversation stays open. Tephra sits underneath as its memory, so it already knows your business instead of starting cold. It is an educational and productivity tool: you own what it makes and you stay the one who decides.

What can Onyx actually do?

It runs the whole business, not one slice. From a single objective it can build an app and a landing page, generate a brand-consistent promo video on real GPU, schedule a run of multi-platform posts, and give you a spoken recap — reading the live web, writing and editing files, and executing code along the way. No single-purpose tool spans that; each of them is a feature of Onyx.

How is Onyx different from other AI tools?

Three structural differences. You own what it makes — competitors rent you your own output and keep you in their host and meter. It already knows your business through Tephra, instead of starting from a blank slate every prompt. And it runs the whole workflow end to end on a fleet of models, reaching top-tier quality at a fraction of the cost by routing across them, rather than doing one narrow step.

How much does Onyx cost?

Two ways to get it. As a subscription, Onyx is part of VIP — $39/mo at the member rate through the Obsidian Metrics community, or $59/mo direct from the website. Or buy the seat outright for $599 once: perpetual access to Onyx with no subscription.

Is Onyx metered?

Yes. Usage is metered. The $599 seat includes approximately $300 of usage credit; when that credit is spent you buy more to keep using it. The seat does not expire — the credit does. On VIP, usage is metered on top of the subscription. We do not sell 'unlimited' or 'lifetime' Onyx.

Does Onyx give investment advice?

No. Onyx is educational and operational. It helps you find, structure, and act on information. It does not provide personalized investment advice, and no result is promised. We are not financial advisors.
