ason-format/ason
ASON (Aliased Serialization Object Notation) is a serialization format designed to optimize token consumption in LLM (Large Language Model) contexts while maintaining human readability and guaranteeing complete round-trip fidelity.
ASON helps you send structured data like customer lists, product catalogs, or analytics logs to Large Language Models (LLMs) more efficiently. It takes your standard JSON data and converts it into a more compact format, which the LLM can still fully understand. This tool is for anyone building applications with LLMs who wants to reduce API costs and improve performance, such as AI developers working with RAG systems or function calling.
Used by 1 other package. Available on npm.
Use this if you are regularly sending structured data (like objects and arrays) to LLMs and want to significantly cut down on token consumption and associated API costs.
Not ideal if your data is extremely unique, non-uniform, or deeply nested, as the token savings might be less significant compared to highly structured, repetitive data.
