Build generative AI solutions with Anthropic’s state-of-the-art model, Claude
Claude 4 by Anthropic
Claude Haiku 4.5, Sonnet 4.5, and Opus 4.5 are hybrid reasoning models offering two modes: near-instant responses and extended thinking for deeper reasoning. These foundation models were developed to build advanced AI agents that can analyze thousands of data sources, execute long-running tasks, write high-quality content, and perform complex actions.
Claude Opus 4.5 is Anthropic's most intelligent model and sets a new standard for production code, sophisticated agents, and complex office tasks. Opus 4.5 delivers state-of-the-art coding capabilities and frontier performance at one-third the cost of previous Opus-level intelligence. It excels at complex, longer-running tasks that require pulling information across multiple data sources, handling ambiguity and reasoning about tradeoffs without hand-holding. With advanced capabilities including tool search and tool use, Claude can scale to use hundreds of tools. Plus an effort parameter, in beta, that lets you balance performance with latency, and cost, Opus 4.5 serves as an ideal virtual collaborator for sustained reasoning and production-grade work. From transforming multi-day coding projects into hours-long tasks to managing comprehensive workflows across finance, cybersecurity, manufacturing, healthcare, and sales, it handles the most demanding enterprise applications with unprecedented reliability.
Claude Haiku 4.5 delivers near-frontier performance matching Claude Sonnet 4's capabilities in coding, computer use, and agent tasks at substantially lower cost and faster speeds, making state-of-the-art AI accessible for scaled deployments and budget-conscious applications. It excels at applications like customer service agents and chatbots where response time is critical, while delivering significant performance improvements for computer use tasks that enable faster and more responsive applications. This model unlocks new use cases where customers previously had to choose between performance and cost, enabling cost-effective agent experiences and supporting multi-agent systems for complex coding projects. This allows Haiku 4.5 to power large-scale financial analysis and research applications with unprecedented efficiency, maintaining Claude's unique character while delivering the performance and cost-effectiveness needed for production deployments across enterprise environments.
Claude Sonnet 4.5 is Anthropic's most intelligent model and its best performing for building complex agents, delivering leading coding capabilities and executing across development tasks while maintaining the optimal balance of speed and cost for production environments. It excels at autonomously planning and executing complex, multi-step workflows and is particularly effective in areas like finance, research, and cybersecurity. With enhanced tool handling and memory capabilities, Claude Sonnet 4.5 serves as an ideal virtual collaborator for sustained reasoning and long-horizon tasks. This allows Sonnet 4.5 to handle sophisticated agent applications with unprecedented reliability, from managing comprehensive research projects to executing end-to-end business process automation across multiple enterprise systems.
Trustworthy AI Systems
Benefits
By default, Anthropic's Claude models have a 200,000 token context window enabling you to relay a large volume of information to Claude. This translates to roughly 150,000 words, or over 500 pages of material. Sonnet 4 and 4.5 now offers an expanded context length of 1 million tokens (preview). This allows for large-scale code analysis, lengthy document synthesis, and the creation of more sophisticated context-aware agents that can maintain coherence across hundreds of tool calls and multi-step workflows, including complete API documentation and interaction histories.
Building Agentic AI with Amazon Bedrock AgentCore and Claude
Amazon Bedrock AgentCore and Claude are revolutionizing enterprise agentic AI by combining frontier model capabilities with production-grade infrastructure. Learn how AgentCore's fully-managed services—including Runtime, Memory, Identity, Gateway, Code Interpreter, Browser Tool, and Observability—enable developers to focus on agent logic and business value rather than building infrastructure from scratch. Learn how Claude's high performance and contextual understanding, paired with AgentCore's enterprise-grade security, reliability, and built-in tools, deliver autonomous agents that can run for up to eight hours with automatic scaling.
