Claude 4, Anthropic's latest AI advancement, introduces two powerful models: Opus 4 and Sonnet 4, setting new benchmarks in coding, reasoning, and AI agent capabilities. Opus 4 excels in complex, long-running tasks, achieving top performance in coding benchmarks like SWE-bench (72.5%) and Terminal-bench (43.2%). Sonnet 4, an upgrade from its predecessor, balances efficiency and precision, making it ideal for everyday use cases. Both models feature extended thinking with tool use, allowing them to alternate between reasoning and external tools like web search. Enhanced memory capabilities enable them to extract and save key facts for continuity in tasks. Claude Code, now generally available, integrates with popular IDEs and GitHub, streamlining developer workflows with inline edits and background task support. Available via Anthropic's API, Amazon Bedrock, and Google Cloud's Vertex AI, these models offer hybrid modes for instant responses or deeper reasoning, catering to a range of user needs. Pricing remains consistent with previous versions, ensuring accessibility without compromising performance.
