Upcoming model updates (December 2, 2026)
Newer OpenAI GPT models are coming to the Basic, Standard, and Premium tiers for prompts in Copilot Studio, Power Automate, and Power Apps. As part of this update, the Anthropic, Grok, and earlier GPT models listed in the following table retire by December 2, 2026. Prompts that use a retiring model automatically move to the replacement model for their tier.
| Tier | Retiring models | Replacement model |
|---|---|---|
| Basic | GPT-4.1 mini | GPT-6 Luna |
| Standard | GPT-4.1, GPT-5 chat, GPT-5.3 chat, Claude Sonnet 4.6, Grok 4.1 Fast reasoning | ChatGPT-latest |
| Premium | GPT-5 reasoning, GPT-5.2 reasoning, Claude Opus 4.6 | GPT-6 Reasoning |
What changes
- Automatic migration: Affected prompts move to the replacement model for their tier by December 2, 2026. You don't need to select a replacement model. Keeping a prompt configured with a retiring model doesn't prevent migration.
- No change to tier pricing: Tier pricing stays the same. Actual consumption and costs can vary with usage, including input and output token counts.
- Possible differences in responses: Responses can differ after migration, including wording, formatting, and how instructions are followed.
- Retiring models are removed: After retirement, the previous models are no longer available in prompts.
