Claude Sonnet 4.6
Versatile multimodal language model for coding, agents, computer use, and production reasoning
Claude Sonnet 4.6 Overview
Claude Sonnet 4.6 is Anthropic's most capable Sonnet model, built for daily production use across coding, agent workflows, long-context reasoning, computer use, and professional knowledge work. It supports adaptive and extended thinking, strong instruction following, high-volume automation, and a 1M-token context window in beta.
Commercial use
How to Use Claude Sonnet 4.6
Overview
Claude Sonnet 4.6 is a versatile multimodal language model built for daily production use across coding, reasoning, agents, and professional workflows.
It is best suited to teams that want a strong balance of capability, speed, and cost for real-world deployment rather than a pure flagship model for only the hardest tasks.
Strengths
High-Performance Coding
Claude Sonnet 4.6 is strong across the software lifecycle, including planning, implementation, debugging, maintenance, refactoring, and codebase navigation.
Agent and Automation Workflows
The model performs well in long-running agent systems that depend on instruction following, tool selection, error correction, and reliable multi-step task execution.
Computer Use
Sonnet 4.6 is a strong fit for browser-based and UI-driven automation tasks where the model needs to understand and act inside software environments rather than only process plain text.
Strong General Knowledge Work
The model works well for research, operations, finance, content, and internal business automation where strong reasoning and professional-quality outputs matter but Opus-level cost is not necessary.
Large Context and Flexible Thinking
Claude Sonnet 4.6 supports adaptive and extended thinking, along with a 1M-token context window in beta. This makes it useful for large documents, long conversations, and workflows that need deeper context retention.
Capabilities
Text-to-Text
Claude Sonnet 4.6 supports general-purpose text generation, reasoning, structured drafting, summarization, coding assistance, and agentic task execution.
Image-to-Text
The model accepts image inputs for multimodal understanding tasks, including visual interpretation, screenshot analysis, and image-grounded reasoning.

More models from Anthropic
Claude Opus 4.7 is Anthropic's highest-capability generally available Claude model. It is designed for demanding coding, agent orchestration, multimodal reasoning, and high-stakes professional workflows, with stronger instruction following, better high-resolution vision, adaptive thinking, and a 1M-token context window.
Claude Haiku 4.5 is Anthropic's fastest and most cost-efficient Claude model. It is built for latency-sensitive applications, high-volume agents, sub-agent orchestration, coding assistance, and budget-conscious deployments that still need strong reasoning and multimodal understanding.
