Built something with LLM4S?

Tell us about it. Open-source projects can be added to this page, and organisations that use LLM4S can list themselves in ADOPTERS.md. Both are voluntary and by pull request: the maintainers do not add anyone on their own.

  • An open-source project

    Open a pull request that adds it to docs/_data/showcase.yml, with a one-line description from your README.

    Edit showcase.yml

  • Your organisation

    Add a row to ADOPTERS.md with your name, a public link and a one-line use case.
