Claude Opus 4.7

Anthropic's next-generation Opus model, built for long-running, asynchronous agents. Building on the coding and agentic strengths of Opus 4.6, it delivers stronger performance on complex, multi-step tasks and more reliable agentic execution across extended workflows. Especially effective for asynchronous agent pipelines where tasks unfold over time - large codebases, multi-stage debugging, and end-to-end project orchestration. Beyond coding, brings improved knowledge work capabilities from drafting documents and building presentations to analyzing data. Maintains coherence across very long outputs and extended sessions, making it a strong default for tasks that require persistence, judgment, and follow-through.

Claude Sonnet 4.6

Sonnet 4.6 is Anthropic's most capable Sonnet-class model yet, with frontier performance across coding, agents, and professional work. It excels at iterative development, complex codebase navigation, end-to-end project management with memory, polished document creation, and confident computer use for web QA and workflow automation.

Claude Opus 4.6

Anthropic's strongest model for coding and long-running professional tasks. Built for agents that operate across entire workflows rather than single prompts, excelling at large codebases, complex refactors, and multi-step debugging. Shows deeper contextual understanding, stronger problem decomposition, and greater reliability on hard engineering tasks. Also excels at sustained knowledge work, producing near-production-ready documents, plans, and analyses in a single pass.

Claude Opus 4.1

Claude Opus 4.1 is an updated version of Anthropic's flagship model, offering improved performance in coding, reasoning, and agentic tasks. It achieves 74.5% on SWE-bench Verified and shows notable gains in multi-file code refactoring, debugging precision, and detail-oriented reasoning. The model supports extended thinking up to 64K tokens and is optimized for tasks involving research, data analysis, and tool-assisted reasoning.

Claude Opus 4

Claude Opus 4 is Anthropic's most powerful model, setting new standards for coding, advanced reasoning, and AI agents. It excels at long-running tasks and complex problem-solving, with capabilities like extended thinking with tool use and improved memory.

Claude Sonnet 4

Claude Sonnet 4 is a significant upgrade to Sonnet 3.7, delivering superior coding and reasoning while responding more precisely to instructions. It balances performance and efficiency for various use cases.
