As we release better and more powerful models, we routinely retire older ones. We plan to take baidu/ernie-4.5-21B-a3b offline at 08:00 UTC on October 29, 2026. At that point, the model will officially be taken out of service, so please complete your migration to the recommended replacement model, deepseek/deepseek-v4.1-flash, before then.

Action required

If your application uses the affected model, please migrate to deepseek/deepseek-v4.1-flash before the retirement time.
