Anthropic enables Claude Opus and Sonnet in Voice Mode
TestingCatalog reports Claude Voice Mode now answers with Opus and Sonnet after a hidden model selector spent roughly three weeks defaulting to Haiku. The change moves Anthropic’s higher-capability models into real-time voice interactions.
Key takeaway
Voice Mode is shifting from a Haiku-only path to Anthropic’s flagship text models, which raises the bar for latency, cost, and speech-interaction quality expectations.
Context
For about three weeks, Claude’s Voice Mode UI exposed a model selector that still routed traffic to Haiku regardless of user choice. TestingCatalog says that behavior flipped today, with Opus and Sonnet responses now coming through the voice interface.
The update is a product-surface change rather than a new model release, but it matters because it puts Anthropic’s strongest general models into spoken, low-latency sessions. That expands the practical use cases for voice agents while tightening the link between chat-model quality and real-time audio UX.
