Deprecated Models: `command-r-03-2024` (and the alias `command-r`) `command-r-plus-04-2024` (and the alias `command-r-plus`) `command-light` `command` `summarize` (Refer to [the migration guide](https://docs.cohere.com/docs/summarizing-text#migration-from-summarize-to-chat-endpoint) for alternatives).
