Question 1

What does self-improvement mean in Harmonia?

Accepted Answer

Harmonia rewrites its own Lisp source code (Ouroboros) and rolls out compiled Rust binaries (Phoenix). Every change goes through 6 safety gates. Failed changes automatically roll back. Improvements sync across agent fleets via Git and persistent storage.

Question 2

What is the difference between Community and paid plans?

Accepted Answer

Community is free and self-hosted — you bring your own OpenRouter key and pay LLM providers directly. Paid plans include a managed Harmonia instance with LLM budget included: Individual (limited), Basic (7x), Pro (20x). Paid plans also include the Harmonia App with A2UI, automatic updates, and priority support.

Question 3

Can organisations use the Community plan?

Accepted Answer

Yes. The Harmonia Community License (HCL-1.0) permits organisations of any size to use, modify, and deploy Harmonia freely. The only restriction is offering Harmonia as a hosted service for third parties — that requires a separate commercial license. For managed infrastructure, see paid plans.

Question 4

What makes the memory system different?

Accepted Answer

S-expression encoding with information-theoretic compression. Nightly crystallisation scores memories by harmony, fact density, decision keywords, and access frequency. High-value entries are preserved; low-signal entries compress via pattern generalisation. A concept graph with domain classification tracks semantic relationships across all memories.

Question 5

What is A2UI?

Accepted Answer

Agent-Adaptive UI. 21 rich components rendered natively on iOS, Android, and Web. All other channels get automatic text fallback. Available through the Harmonia App on paid plans.

Question 6

What is OS⁴?

Accepted Answer

A FreeBSD-based operating system with Harmonia integrated as a native runtime. Supports x86 and ARM. Used in industrial robotics, automotive, agriculture, avionics, and logistics.
