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.

One AI API key for text, image, video, and code models
Call many different models through one base URL and one API key, so existing OpenAI-style clients and SDKs usually need only minor changes.
Access text and reasoning models alongside image, video, and audio/music generation endpoints from the same integration.
Route routine traffic through a value tier to reduce spend, and move critical workloads to an official tier when stability matters more than cost.
Manage credentials and usage in one place instead of juggling separate accounts, quotas, and invoices across vendors.
