Anthropic to Upgrade Claude Voice Mode with Opus, Sonnet, and Thinking Controls
Anthropic is reportedly planning to update Claude's voice mode, allowing users to switch between the Opus, Sonnet, and Haiku models. The update will also introduce a setting to control the model's "thinking" level during voice interactions. This update will allow users to leverage more powerful reasoning and analytical capabilities directly within voice conversations, moving beyond the lightweight Haiku model. It reflects the industry trend of integrating advanced reasoning controls into real-time voice AI. Currently, Claude's voice mode is limited to the Haiku 4.5 model. The upcoming selector will let users choose their preferred model, though the rumored "Claude Fable" model is currently absent from the options.
## BACKGROUND
Claude is a family of large language models developed by Anthropic, consisting of different tiers: Haiku for speed, Sonnet for balanced performance, and Opus for complex reasoning. Voice mode enables real-time spoken conversations with these models instead of text-based prompting.
