Anthropic's frontier AI workspace powered by Claude 5.5 for agentic coding, analysis, and nuanced writing.
Combines frontier Claude Opus 5.5 and high-speed Sonnet 5.5 with configurable extended thinking, up to 1M-token context windows, and 128K-token outputs.
Pro, Max, and Team Premium plans bundle Claude Code for autonomous command-line software engineering, test execution, and repository-wide refactoring.
Renders live interactive web apps, visualizations, spreadsheets, and formatted PowerPoint decks in a dedicated workspace panel alongside the chat.
Grounds conversations in shared project knowledge bases and connects directly to local filesystems, GitHub, Slack, and internal databases via MCP.
Build, test, and deploy production-grade voice AI agents over API
Configure speech recognition, an LLM reasoning layer and text-to-speech through one API instead of integrating several vendors separately.
The platform handles real-time audio streaming, interruption handling and call state so conversations feel natural and responsive.
Provision Vapi phone numbers or bring Twilio, Vonage or Telnyx, and support both inbound and outbound calling from the same agent.
Simulate calls before launch, then track transcripts, effectiveness metrics and compliance signals across every production call.
Stronger multimodal voice capabilities and reasoning models, but less refined inline artifact generation and agentic coding.
