# langflow vs CosyVoice

langflow and CosyVoice share 5 technologies: FastAPI, pyarrow, uvicorn, Rich, and Pydantic. Both are written in Python.

- [langflow-ai/langflow](https://seerepo.com/r/langflow-ai/langflow): Langflow is a powerful tool for building and deploying AI-powered agents and workflows.
- [QwenAudio/CosyVoice](https://seerepo.com/r/QwenAudio/CosyVoice): Multi-lingual large voice generation model, providing inference, training and deployment full-stack ability.

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
