A simple chat started with Haiku can deepen by switching to Opus. This flexibility provides the advantage of instant responses to different needs. Model switching significantly enhances user experience. ## Business-Specific Solutions Opus and Sonnet models can perform complex analyses and execute tasks on behalf of users. For example, they can turn meeting notes into one-page summaries or automatically reschedule your calendar if your train is delayed. These features are optimized for professional use. ## Multilingual Support Expands Voice mode is now available in 8 new languages besides English, including French, German, Spanish, Hindi, Indonesian, Italian, Japanese, Korean, and Portuguese. This expansion reflects Anthropic's goal of reaching a global user base. ## User Behavior Shapes Development The company notes that voice mode was used differently than expected. Users began employing it not just for quick questions but to discuss serious business problems. This feedback influenced the decision to add voice support to more powerful models. ## Competition in AI Assistants Anthropic's move intensifies competition in the voice AI assistant market. Users now have an alternative that offers deeper analysis and multilingual support. This development may push other industry players to accelerate similar features. ## Sources covering this story - https://www.theverge.com/ai-artificial-intelligence/970065/anthropic-voice-mode-claude-opus-sonnet-haiku-ai — --- _Summary written by Brifing from the original reporting.
