Workers AI — Planned model deprecations (May 30, 2026)
Key Points
- Deprecation date: 2026-05-30
- Kimi K2.5 will alias to K2.6
- Update model IDs before deprecation
Summary
Cloudflare is refreshing the Workers AI model catalog and will deprecate a number of models on 2026-05-30. Remove references to deprecated model IDs before that date. @cf/moonshotai/kimi-k2.5 has an extended deprecation date and will be automatically aliased to @cf/moonshotai/kimi-k2.6 on 2026-05-30 (note the higher price for K2.6).
Key Points
- Action required: update application code, configs, and infra to stop using deprecated model IDs before 2026-05-30.
- Kimi K2.5: requests will be aliased to
@cf/moonshotai/kimi-k2.6on 2026-05-30 — reviewk2.6pricing and capabilities and test behavior before the cutover. - Recommended replacements (examples):
@cf/zai-org/glm-4.7-flash,@cf/google/gemma-4-26b-a4b-it,@cf/moonshotai/kimi-k2.6. - Scope: the deprecation list includes multiple Llama, Mistral, Gemma, Phi-2, SQLCoder, UForm, and BART variants — consult the Workers AI model catalog for the full list.
- LoRA and -fast variants: many
-fastand-loravariants remain active now (e.g.-loraand-fastsuffixes listed), but LoRA models may be deprecated in the future — plan for retraining/migration of LoRAs. - Testing & validation: run integration tests for tool-calling, vision, and pricing changes; update CI and deployment manifests to reference replacement models.
