This is what possible means here: real shipped surfaces, built end to end by one person in Australia, on an architecture designed to be understood rather than believed on faith.
Opta runs on the brain you choose: frontier cloud models when you want their reach, or a fully local brain through Opta Local. Owning the stack means the choice stays yours — two things make that real.
Choose the local brain and your data, your prompts, your context never leave your hardware. No model provider sees what you work on — not even us.
Frontier cloud models when a job wants their scale; your own Apple Silicon when it wants privacy or zero per-token cost. Switch brains without losing your agent.
Local-first needs an inference engine, and the ones on the shelf treat local AI as a commodity runtime rather than something to optimise. So we engineered our own: Apple-Silicon-native, tuned across the GPU and Neural Engine of the machine in front of you.
Meet Opta LocalThis interpretation is the output of a loop we run every day. It never closes, and what no longer holds gets dropped.
Revise feeds back into use. The belief stays alive, never frozen.
High AI competence shouldn't be a developer privilege. Opta Learn is the path from chat-only user to architecture-grade user: the steep part of the curve, flattened.

Opta builds one stack and points it two ways: apps you run, and services you hire. Pick your door.
The Opta Agent in your hands: deep competency underneath, a simple surface on top, and a brain that can run entirely on your own Apple hardware.
