Test before switching

- Test your prompts, structured output, streaming and tool calls on staging.
- Compare quality, latency, pricing and rate limits on your workload.
- Keep a rollback path while the old model remains available.

What should I migrate summarize to?
Cohere has not published a successor for this model. That makes the decision yours, and it is worth treating as an opportunity to compare providers rather than defaulting to whatever is nearest. Endpoint responsiveness is measurable; model quality claims mostly are not.

How is this calendar maintained?
Entries are pulled from provider documentation by an automated weekly job and every one carries a link to its source. Nothing is inferred from blog posts or social media. When a provider changes a date, the change appears here after the next run and is visible in the changelog. The full calendar across all providers is on the deprecations page, and this provider’s own list is at Cohere deprecations.
