The Anthropic Claude API provides access to Claude's family of models, including Claude Opus 4.5 (launched November 24, 2025) and ultra-fast Sonnet 4.5. November 2025 updates introduced major API features: Programmatic Tool Calling and Tool Search to reduce token consumption, an 'effort' parameter to balance cost and performance, and guaranteed structured outputs in JSON format. With a massive 200K+ token context window and industry-leading reasoning capabilities, Claude excels at complex tasks like code analysis, document processing, and agentic workflows. Opus 4.5 leads SWE-bench Verified. Known for strong coding performance and safety, Claude is trusted by enterprises and developers worldwide.

Claude Opus 4.5

✓

Anthropic's most powerful AI model with state-of-the-art coding and agentic capabilities

Claude Opus 4.5 is Anthropic's flagship AI model, released November 24, 2025. It delivers state-of-the-art performance on coding benchmarks, leading SWE-bench Verified and outperforming all frontier models. With the new effort parameter, developers can customize the balance between speed and capability. The model features context compaction for longer-running agentic sessions, using up to 65% fewer tokens for long-horizon coding tasks. Opus 4.5 is the most robustly aligned model to date, with industry-leading resistance to prompt injection attacks.

Vercel AI SDK

✓

The AI Toolkit for TypeScript

The AI SDK is the TypeScript toolkit designed to help developers build AI-powered applications with Next.js, Vue, Svelte, Node.js, and more. Integrating LLMs into applications is complicated and heavily dependent on the specific model provider you use. The AI SDK abstracts away the differences between model providers, eliminates boilerplate code for building chatbots, and allows you to go beyond text output to generate rich, interactive components.
