Expanded LLM models available in Agent Studio
Builders have full visibility and control over which LLM model powers their Genies in Agent Studio, with support for versioned models across Anthropic and OpenAI.
- Model selection — Choose specific versioned models across Anthropic (Sonnet 4.x) and OpenAI (GPT-5.x) directly in Agent Studio.
- Latest model access — Take advantage of the newest model releases as they become available from leading providers.
- Model audit logs — Track LLM model version changes and timestamps for each Genie, making it easier to correlate behavioral differences and troubleshoot.
- Auto-migration for deprecations — When LLM providers sunset older models, Genies automatically upgrade to a recommended replacement, preventing service disruption.
Upcoming auto-migration — April 14, 2026: Claude Sonnet 3.7 reaches end-of-life and all Genies still using it will automatically migrate to Sonnet 4.6. Rollback will not be available. Builders can upgrade early using the new model selection dropdown — testing in advance is recommended to ensure expected behavior.
