Non-destructive compression gateway for AI coding agents. Cuts token bills 25% on turn 1 to past 85% in long or saturated sessions, and fits ~3× more turns in the same context window. Powered by our open-source code-native 4B model. Drop-in for Claude Code, Cursor, Codex, OpenHands, and any BASE_URL agent.

<p align="center"><b>A non-destructive compression gateway for coding agents — cut your input-token bill without changing your agent.</b></p>
<p align="center">Paritok sits between your agent and the LLM as a drop-in proxy. On every request it strips the tool-schema bloat, compresses tool results and file reads, and summarizes stale history — then forwards upstream, billed on the compressed tokens. Nothing is ever permanently discarded: the agent pulls back any exact original on demand. Works with <b>Claude Code, Cursor, Codex, OpenHands</b>, and any agent that honors <code>BASE_URL</code> — <b>you don't change a line of your agent</b>.<br/><br/>Powered by the <b>first open-source 4B compression model trained specifically for coding agents</b> (45K real agent trajectories). Cut input token bills from <b>~25% on turn one</b> to <b>past 85% in long, context-saturated sessions</b>, and fit <b>~3× more turns</b> in the same context window.</p>
