Please be advised that QwenCloud will continue to undergo rapid iterations and release higher-performing models between the publication of this notice and the actual retirement dates. Consequently, the replacement recommendations provided in this notice will not be frequently updated with the release of new models. We highly recommend regularly visiting the Models page during your migration and daily operations to ensure you can flexibly select the latest and most suitable models for your specific business needs.

Change impact

Upon retirement, these models will no longer support inference, and any applications or services continuing to call them will fail to receive responses. If you are currently using any of these models, please ensure that you complete the API migration, parameter tuning, and business validation before October 10, 2026, to avoid any disruption to your production services. Additionally, the corresponding models supported by the Coding Plan and Token Plan listed above will also be retired simultaneously. If you have purchased prepaid resource packages, you may submit a support ticket to request a pro-rata refund for the unused resources.
