What will be open
The layer that understands documents, images, audio and video; long-term memory and the relationships between people and events; tool calls, long-running tasks and human review.
How it will be open
Changes flow back into the public core; major changes are discussed openly as proposals first; the roadmap and compatibility information are published together.
Who with
Developers, scenario authors, and people trying it on all kinds of devices. The project is still early, and the rules will be set together with the community.
