Ahrefs Domain Rating benchmarked 3 Nov 2026, rebuilt 3 Nov 2026.
A data format that injects a metadata layer allowing comments, tags, and attributes for LLM interaction while remaining parser-ignorant.
What it is
AK Data is a data format designed for efficient large language model communication. It reduces syntactical noise by up to 50% compared to JSON through schema-first design and positional tuples, achieving 21.7% token savings in compact mode. The format supports metadata injection via tags and attributes that are visible to LLMs but invisible to parser logic, enabling context passing without affecting application behavior. AK Data includes full support for C-style comments, multiline strings, and mixed records, with implementations available in TypeScript/Node.js and Python, plus a command-line interface for integration into CI/CD pipelines.
What it is built with
- Schema-first design with type validation
- Metadata injection with tags and attributes
- C-style comments and multiline strings
- Positional tuples for high density
- CLI for file conversion and testing
- Escaped identifiers with backticks

Questions from the bench
- What languages does AK Data support?
- AK Data is available in TypeScript/Node.js via npm and Python via PyPI, with a command-line interface available for Python.
- What can you do with metadata injection in AK Data?
- Metadata injection allows you to pass context to the LLM through tags and attributes (e.g., deprecated flags, source origins) that are visible to the model but invisible to application logic.
- How does schema-first design prevent format issues?
- Schema-first design lets you define structure once, and AK-Data validates data types (int, number, bool) before they reach your LLM context, preventing hallucinated formats.
