As of June 30, 2025, claude-3-opus is deprecated. The expected removal date for this model is January 2026. Anthropic recommends migrating to claude-opus-4-0 before January 2026. We strongly recommend carrying out this migration since claude-3-opus support will be removed from future Cognigy.AI versions. Refer to the list of all upcoming removals on the Deprecations and Removals page.
