Anthropic Unveils Claude Opus 5 and Expands Voice Capabilities to Opus and Sonnet

Key points

Anthropic launched Claude Opus 5, delivering near-top-tier intelligence at half the cost of its Fable 5 model, priced at $5 per million input tokens and $25 per million output tokens ^[8].
Claude Opus 5 serves as the default model on Claude Max, a $100-per-month subscription plan, and is also available on Claude Pro ^[9].
Claude's voice mode has expanded beyond the lightweight Haiku model to support the more powerful Opus and Sonnet models, enabling complex reasoning and voice-controlled tool usage ^[7].
The updated voice functionality integrates deeply with connected workplace tools like Slack, Canva, and Figma via the Model Context Protocol ^[7].

The Rise of Claude Opus 5

The artificial intelligence race has officially entered an era of economic efficiency. Anthropic has released Claude Opus 5, a high-performance model engineered to deliver nearly all the intelligence of its flagship Claude Fable 5 at half the operating cost ^[8]. By pricing input tokens at $5 per million and output tokens at $25 per million, the company is shifting industry focus away from raw, unchecked capability and toward the financial viability of daily enterprise workflows, coding projects, and autonomous agent operations ^[8].

Market availability for the new model is immediate across Anthropic’s ecosystem. It has been designated as the default model for Claude Max, the company’s premium subscription tier starting at $100 per month, and stands as the most robust model accessible to subscribers on Claude Pro ^[9].

Voice Mode Gets Intelligent

Beyond raw model economics, conversational AI is taking a major leap forward. Anthropic has upgraded its voice mode infrastructure, moving past the lightweight Haiku model to integrate the advanced reasoning capabilities of Opus and Sonnet ^[7]. Previously limited by reliability constraints, the voice interface now handles sophisticated conversational tasks with greater accuracy and depth [[3, 6]].

This upgrade transforms voice interaction from a novelty into a functional workspace asset. Users can now speak naturally to direct Claude through complex workflows, utilizing connected applications and tools entirely through voice commands [[5, 7]].

Ecosystem and Workflow Integration

The convergence of advanced voice models and multimodal architecture is deeply tied to enterprise productivity. Powered by the Model Context Protocol, the enhanced voice mode allows users to seamlessly interact with workplace platforms like Slack, Canva, and Figma hands-free ^[7]. Whether managing agent tasks or orchestrating multi-app projects, the integration bridges the gap between conversational convenience and heavy-duty execution ^[7].
