dweve-ai/hedl
Token-efficient data serialization for LLM/AI. 50% fewer tokens than JSON, 93% better value/token. Rust, schema validation, LSP.
This helps AI application developers significantly reduce the cost of communicating structured data to Large Language Models (LLMs). It takes your existing JSON, converts it into a token-efficient format, sends it to the LLM, and converts the response back to JSON. AI engineers and developers building LLM-powered applications who are concerned about API costs will find this useful.
Use this if you are sending structured data like user records, product catalogs, or order histories to LLMs and want to cut down on token usage and API costs without changing your application code.
Not ideal if your application does not frequently send structured data to LLMs or if you are not concerned about the token costs associated with LLM interactions.
