Open-Source Desktop Agent Chimera

The author has released Chimera, an open-source desktop agent that transparently displays the actual token costs, tool calls, and memory layer hits for every single step, rather than hiding them behind a UI.
Its two core designs are:
- Cost-aware routing: Employs a cascade strategy of weak model → gating → medium model → gating again → fusion, avoiding blindly triggering multi-model fusion for a single answer. The author noted that naive fusion can incur roughly 11x the token cost.
- Honest memory: Persists facts across sessions, supports json/sqlite with optional embedding and FTS fallback, and applies taint tracking to untrusted content to prevent unverified information from masquerading as verified facts.
The project is open-source. After installing via pip install "chimera-agent[desktop]" and running chimera app, it is currently still in its alpha stage.
