The most interesting part of this is probably Salesforce taking such an aggressive marketing position by calling it 'SlackGPT', when the 'GPT'-suffix is currently strongly associated with OpenAI.

Particularly ironic since Slack doesn't seem to be launching any type of GPT-like model as part of this announcements, it appears just to be a rebranding of a bunch of APIs Slack already has, with the enterprise software marketing dress-up as a revolutionary AI productivity boost.
