On May 12, 2026, StepFun AI notified users that its international version will stop operations on May 27, 2026. The company cited a final shutdown of the service, with all chat histories being deleted upon closure. Users can export their data by manually copying conversations or using the 'Share-Generate Image' export feature. No reasons were given for the shutdown, and no migration plan was offered. The announcement affects all users of the StepFun AI International Version, including those using the Step-3.5-Flash model via OpenRouter.
The decision leaves users with a short two-week window to preserve their data. StepFun AI likely exits the competitive international AI assistant market, which is dominated by players like ChatGPT, Claude, and Gemini. For users who built workflows or stored valuable conversations, this is a sudden loss of service. The company provided no alternative or replacement service. Affected users should act quickly to export their chat history and seek alternative AI platforms.
- StepFun AI International will stop operations on May 27, 2026, with all chat histories deleted.
- Users have until May 27 to export data via copy/paste or the 'Share-Generate Image' option.
- Contact for support is feedback@stepchat.cn; no reason or migration path was provided.
