Even though the README.md calls the license the Databricks Open Source License, the LICENSE file includes paragraphs such as
> You will not use DBRX or DBRX Derivatives or any Output to improve any other
large language model (excluding DBRX or DBRX Derivatives).
and
> If, on the DBRX version release date, the monthly active users of the products
or services made available by or for Licensee, or Licensee’s affiliates, is
greater than 700 million monthly active users in the preceding calendar month,
you must request a license from Databricks, which we may grant to you in our
sole discretion, and you are not authorized to exercise any of the rights under
this Agreement unless or until Databricks otherwise expressly grants you such
rights.
