The Opta Stack

One AI, continuously optimised. Built by one person in Australia. Pick the apps you need — they all run on the same identity, settings, and intelligence.

The big picture

So what actually is Opta?

Opta is a single unified AI you talk to. Behind the scenes, every Opta response is shaped by an internal team of complementary models — picking the right tool for each kind of thinking — plus a dedicated researcher that keeps Opta's knowledge fresh and accurate.

The user only ever sees Opta. Everything else is invisible infrastructure designed to make Opta more competent, more prepared, and more informed than any single AI model could be on its own.

The thesis — architecture beats parameters. Opta wins not by having the biggest model, but by having the smartest system orchestrating specialised parts.
Anatomy

Three layers, one mind

BODY · execution BRAIN · cognition Opta the whole MIND · reflective mode context ↓ ↑ action

Every task flows through the same cycle. Brain reasons. Body executes via tools, retrieval, and harness. Mind isn't a separate layer — it's the same system turned inward to reflect, learn, and improve. The arrows between them carry context, actions, and learning records.

BRAIN
Cognitive engines — models that reason, decide, synthesise. Routed by task type and stakes.
BODY
Execution infrastructure — harness, tools, skills, retrieval, memory, apps, runtime.
MIND
Reflective mode — same system turned inward. Triggered by learning records and reviews.

Talk to your AI about Opta

Tell Grok, Perplexity, or Gemini to read this site.

Insight is structured to give external AIs instant grounding context. When you're chatting with any AI that doesn't already know what Opta is, paste one of the URLs below and ask it to read.

The /llms.txt file follows the emerging convention for AI-readable site indexes. /depth is the full grounding page — Anatomy, identity, component map, philosophy, mission, principles.
