Hello everyone, today I bring you the latest blockbuster release of Anthropic - Claude 4 : including the top coding "big shot" Opus 4 and the flexible and efficient Sonnet 4. The two major models are released together to fully upgrade your AI office and development experience!
1. What is the strength of Claude 4? ?
1. Claude Opus 4 - The world's strongest "coding power"
• SWE-bench: 72.5%, Terminal-bench: 43.2%, outperforming similar models • Sustained combat capability: can work continuously for several hours and handle thousands of complex tasks • Industry Verification:
• Cursor : Strongest code comprehension • Replit : Large-scale changes to multiple files are more accurate • Rakuten : 7 hours of independent reconstruction and stable output
2. Claude Sonnet 4 – A new star that balances performance and efficiency
• SWE-bench: 72.7%, closely following Opus 4 • Better controllability: more precise response to commands • Partners’ Voice:
• GitHub : Copilot Coding Agent Foundation • Manus : Complex instruction following ability is greatly improved • Sourcegraph : Deeper problem understanding and elegant code
2. Three major new features?
1.
Extended thinking + tool use (Beta)
Claude 4 can switch freely between "thinking" and "tool calling" (such as network search, file reading and writing) to give more accurate and reliable answers.
2.
Parallel tool execution & memory enhancement
• Call multiple tools in parallel, high efficiency • Automatically generate "memory files" under local file access, making long-term tasks more coherent • Example: Opus 4 records “navigation guides” while playing Pokémon, perfect for decision-making!
3.
Claude Code is now available
• VS Code, JetBrains native plug-in, Inline editing, real-time collaboration • GitHub Actions, Claude Code SDK background task support • @Claude Code in PR can automatically fix CI and respond to review comments
3. New API Capabilities: Building Smarter AI Agents?
Anthropic API adds four new killer features:
• Code execution tool : sandbox operation, safe and controllable • MCP connector : seamless connection with external systems • Files API : read and write local/cloud files • Prompt Cache : Hit rate soared in 1 hour, saving costs
4. How to get started? ?️
1. Open the Anthropic console or search for "Claude" on Amazon Bedrock or Google Vertex AI 2. Choose Opus 4 or Sonnet 4:
• Opus 4: $15 (input) / $75 (output) per million tokens • Sonnet 4: $3 (input) / $15 (output) per million tokens
3. Configure tools and file permissions to experience "extended thinking" and "automatic memory" 4. Install the VS Code/JetBrains plugin and enable Claude Code with one click
summary
Claude 4's Opus 4 and Sonnet 4 take AI coding, reasoning, and agent processes to the next level. Whether you are deeply engaged in scientific research, writing, or daily coding, or want to quickly incubate intelligent applications, you can find the right help.
