Context as Image. OmniGlyph is a local compression proxy for LLMs: it renders the bulky parts of each request — system prompt, tool docs, old history, large tool outputs — as dense PNG pages and lets the model read them. Models bill text per token but bill an image by its dimensions, not by how much text is packed inside. Measured end-to-end bill reduction: 59–70%.

The proxy only converts when the exact per-provider billing math says it wins, and only for models that passed the reading benchmark (fail-closed gate).
