Current notes 2026
Slack AI add-on can no longer be purchased; AI features integrated into Pro/Business+/Enterprise+, Business+ price increased (updates article, effective from the first renewal after 2025-08-17). Price does not decrease if AI features are deactivated (q4). Salesforce sub-processor documentation (2026-10-02) lists Microsoft Azure as generative AI provider for Slack and You.com for Slackbot web search (q8). Slack sub-processor page redirects to this documentation.
Open points of the review
- Which LLMs/models Slack AI uses: the AI data usage page, too, names only "third-party LLMs", the AI principles page states "The LLMs we use are deployed inside Slack's cloud environment, so model providers do not have access to your data"; model names not published. Relationship to the listing of Microsoft Azure (USA) as generative AI provider in the Salesforce sub-processor documentation still not explained.
