Workers AI moved Kimi K2.5 retirement from 10 May to 30 May 2026 and automatically aliases requests to the higher-priced K2.6 model.

Previous state

Kimi K2.5 remained directly addressable until the original 10 May retirement target.

Current state

Retirement moved to 30 May and requests automatically resolve to Kimi K2.6.

Who needs to care

Workers AI applications calling @cf/moonshotai/kimi-k2.5.

What to do

Evaluate K2.6 capability and pricing and update explicit model governance rather than relying silently on the alias.

What the source does not prove

K2.6 has different pricing and potentially different behaviour; the alias is not guaranteed to be impact-free.
