The use of LangExtract involves the following costs and deployment methods:
- Open source policy: released under the Apache 2.0 license, the code is fully open source and hosted on GitHub, allowing community contributions
- Cost of use: the tool itself is free, but there are API call fees for using cloud-based models (e.g., Gemini); local models (e.g., run through Ollama) do not require API keys and related fees
- Deployment: Supports cloud model API calls and can also be extended to third-party local model inference endpoints
- Environment Requirements: Python-based development, support for modern Python package management methods, deployable in a variety of development and production environments
Overall, LangExtract provides flexible deployment options, allowing users to choose the right model and runtime environment for their actual needs and budget.
