About Respond.io
Respond.io upgraded its AI Agents to GPT-5.6 and added TikTok Business Messaging for US accounts.
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.
