Closed AI makes you a reseller; open AI makes you an owner
Build on a closed API and you're effectively reselling someone else's model at their price — your margin is whatever they leave you, and your business exists at their discretion. Build on open weights running on your own compute and the model is a tool you own, the margin is yours, and no vendor sits between you and your customers. That's the difference between renting a storefront and owning the building.
What makes it ownable
Open-weight engine
The models powering your product are open weights — runnable, inspectable, and yours to keep, not a license that can be pulled.
Your own compute
The engine runs on your Modal, so your costs are compute at cost — not a per-call markup that grows with every customer you serve.
Your margin
No middleman skim on each generation means the spread between what you charge and what you pay stays yours.
Your data moat
Your customers' data lives in your own database — a real asset that compounds, not something pooled into a vendor's platform.
Your outputs to sell
Everything produced is yours, free to package, price and sell however you choose.
Repeatable
The same owned stack stands up business after business — your build, your accounts, every time.
Open-source business vs. API reseller
| The model | Open weights you own | Licensed access you rent |
| Your cost | Compute, at cost | Markup per generation |
| Your margin | Yours to keep | Whatever's left over |
| Your data | Your asset | Their platform |
| Your business | You own it | Exists at their will |
Questions about ownership
What makes this an open-source AI business?
The models in the production path are open weights running on infrastructure you own. You're not licensing access to a closed model — you're operating a stack you control end to end.
How does open source help my margin?
No per-generation API markup. You pay your own compute at cost, so the spread between your price and your cost stays with you instead of a vendor.
Do I own the customer data and outputs?
Yes. Customer data lives in your own database and the outputs are yours — both real, sellable assets that belong to your business.
Is the whole thing open source?
The production models are open weights on your compute. The platform's intelligence and governance layer is proprietary and runs on our side — it directs the work; your owned stack does the work.
Own it, don’t rent it.
Your compute. Your data. Your outputs.
