~ > spark model list -- 26 models, one list
spark model NAME serves one; spark ember NAME adds a second, for conversations. auto picks among the rows tested on the line under Apache-2.0 or MIT; any other license is shown and asked about before the download. Every file is sha256-verified. Your own rows: spark model add URL --license. A row is a pull request: CONTRIBUTING.md.
source: models.env on GitHub -- this page is that file at spark v1.37
