Deploy Smarter AI Agents directly into Slack Threads
Let AI agents participate in team discussions autonomously.
Configure your ChatGPT Workspace Agents to use GPT-5.5 with 'Smarter Slack thread replies' enabled to allow them to follow and join conversations without constant @mentions.
The Scenario
Your team is brainstorming a project in Slack. You want an AI expert to stay in the conversation, answering follow-up questions from colleagues automatically without you having to manually trigger it for every message.
Before & after
You had to @mention the agent for every single follow-up question in a Slack thread. Managing a group discussion with an AI required constant manual tagging, taking 5–10 minutes of active monitoring per thread.
Select your agent, set reasoning to 'High', and ask it to respond to Slack threads. The agent will now autonomously monitor and reply to follow-ups in the thread, managing the project while you work elsewhere, costing you 0 minutes of manual management.
The Prompt
Create a workspace agent using GPT-5.5 with [HIGH/MEDIUM/LOW] reasoning effort. Set it to 'Slack thread mode' so it can respond to all relevant follow-up messages in a thread without needing a new @mention for each reply.
Workspace agents on the Business plan now support GPT-5.5 and can be configured for smarter Slack thread participation.
