Every era creates its file format. AI doesn't have one yet.

Print gave us PDF. Photography gave us JPEG. Music gave us MP3. The AI era generates more content than any previous era — but has no format to carry trust, provenance, or verification with that content. Today I'm releasing AKF — Agent Knowledge Format. Open source. Open spec. What is it? AKF is EXIF for AI. ~15 tokens of JSON that embed directly into any file: Trust scores — how reliable is this content? (0-1) Source provenance — where did it come from? (SEC filing → analyst → AI summary) Security classification — who can see it? (public, internal, confidential) AI attribution — which model generated it? Compliance metadata — does it meet EU AI Act, SOX, NIST requirements?
