echoChain
echoChain is an evaluation tool that measures how an answer changes when language models rewrite it repeatedly in a loop.
echoChain is an evaluation tool that measures how an answer changes when models rewrite it in a loop. It lets users analyze iterative text degradation and drift across model generations. The tool integrates with OpenRouter via an API key and supports baseline scoring through sentence-transformers. Users can dry-run packaged seeds, execute live cycles, and summarize completed runs. Configuration, run flags, output files, and exit codes are detailed in the usage guide.
