Official VSCode extension for the ZEON data format.
ZEON is an ultra-lightweight, tabular data format engineered specifically for AI token economy. By eliminating the heavy syntax and nested brackets found in JSON, it provides LLMs with highly structured grid data using the absolute minimum number of tokens possible. This drastically reduces prompt costs and speeds up generation while remaining clean and readable.
JSON vs ZEON (Token Economy)
ZEON can reduce your LLM payload token usage by up to 56% compared to standard JSON, while keeping the data perfectly structured for AI consumption.
