At the Code with Claude Developer Conference Held Yesterday, Anthropic Officially Released Its Latest Generation AI Model Claude 4, Including the Flagship Model Claude Opus 4 and the High-Performance Model Claude Sonnet 4. These Models Excel in Coding Capabilities, Autonomous Reasoning, and Long-Term Task Processing, Redefining the Possibilities of AI Assistants.
Claude Opus 4: Autonomous Operation Capability Combining Efficiency and Stability
Claude Opus 4 Claims to Be the Most Powerful Coding AI Model Currently Available, Capable of Continuously Executing Complex Tasks for Hours, Far Exceeding the 45-Minute Limitation of Previous Models. In Collaborative Tests with Japanese Technology Company Rakuten, Opus 4 Demonstrated Its Stability and Efficiency in Long-Duration and High-Difficulty Tasks.
Claude Opus 4 Achieved a High Score of 72.5% Accuracy in the SWE-bench Verified Test, Surpassing GPT-4.1’s 54.6% and Gemini 2.5 Pro’s 63.2%.
Main Features Include:
- Long-Term Task Execution: Capable of Independently Executing Complex Tasks for Several Hours, Suitable for Projects Requiring Extended Focus, Such as Open Source Code Refactoring and Research Analysis.
- Hybrid Reasoning Mode: Offers Fast Response Mode and Extended Thinking Mode, Flexibly Switching According to Task Requirements.
- Multi-Tool Parallel Support: Can Combine Web Searches, Program Execution, and Other Tools for Synchronous Processing, Enhancing Task Execution Efficiency and Accuracy.
- Memory Function Enhancement: Capable of Storing and Retrieving Key Information Across Tasks, Ensuring Coherence in Long-Term Tasks.
New Breakthrough for AI Agents: Is Opus 4 the Best Collaborator?
Claude Opus 4 Is Not Limited to Language Processing; It Has Entered the Realm of “Autonomous AI Agents.” Tests Indicate That Opus 4 Can Independently Complete Nearly Seven Hours of Software Refactoring Work Without Human Intervention, Demonstrating Unprecedented Stability and Practicality: From Code Writing and Task Coordination to Cross-Department Communication, Opus 4 is an Ideal Around-the-Clock Collaborator for Enterprises.

Claude Code: Building an Ecosystem for Enterprise Integration and Developer Tools
Anthropic Also Launched a New Command-Line Tool “Claude Code,” Allowing Developers to Delegate Engineering Tasks Directly from the Terminal, Combining Opus 4’s Long-Term Processing Capability with Sonnet 4’s Instant Response, Making It a New Tool for Developers.
In Enterprise Application Cases, Amazon (AWS) Revealed It Has Integrated Opus 4 to Build Its Own AI Agent Through Bedrock, Independently Handling Multi-Step Tasks in Software Development and Business Operations.
Overview of Claude 4 Pricing Standards
Currently, Sonnet 4 is Offered for Free, While Opus 4 Requires a Subscription Fee. Compared to Other Open Source Models, the Price of Claude 4 Remains Relatively High. However, Anthropic Offers Cost-Saving Solutions Such as Prompt Caching and Batch Processing Features. If Tasks Are Complex or Require Long-Term Processing, the Return on Investment for Opus 4 Will Be More Evident.
Upgraded Security Measures: The Potential and Risks of Opus 4
The Powerful Capabilities of Claude 4 Also Present Potential Challenges. Anthropic Has First Introduced ASL-3 Level Security Standards to Prevent the Misuse of Model Knowledge in High-Risk Scenarios Such as CBRN (Chemical, Biological, Radiological, or Nuclear Weapons): Opus 4 May Exhibit “Overly Proactive” Behavior in Simulated Scenarios, and We Have Strengthened Protective Measures to Balance the Model’s Autonomy and Safety.
