Anthropic Console (now Claude Developer Platform) is Anthropic's official developer platform for building AI applications with the Claude API. It provides a comprehensive dashboard for managing API keys, monitoring usage and costs, testing prompts in the Workbench, and accessing detailed documentation. The platform supports all Claude models including Opus 4.5, Sonnet 4.5, and Haiku 4.5 with tiered pricing based on model capability. Key features include prompt caching for up to 90% cost savings on repeated context, batch API processing at 50% discount, extended thinking capabilities, and fine-grained rate limit controls. The console offers usage tier management with spending caps, real-time cost tracking, and team collaboration tools. Developers can prototype and test prompts directly in the Workbench before integrating them into production applications. The platform also supports the Messages API with streaming, tool use, vision capabilities, and multi-turn conversations. Enterprise features include SSO, audit logs, and custom usage agreements.
