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.

Start from a target or your own sequence and have Cradle design an optimized plate of candidates informed by your data and domain knowledge.
Improve efficacy, developability, and manufacturability in parallel rather than one property at a time, compressing time to a target profile.
Every round incorporates results from the previous one, so experimental data compounds across campaigns and prior failed programs stay useful.
Everything in the web application is exposed through the API, so computational teams can script campaigns and wire Cradle into existing pipelines.
