Background and latest developments of CLAUDE AI assistant
Anthropic Team and Technical Philosophy
Claude It is an American startup company Anthropic The R&D and founding team largely comes from OpenAI. Anthropic is known for its "safety first" philosophy, focusing on "reliable and responsible AI," and has attracted investment from Google and Amazon. In May 2025, Anthropic released its latest flagship model. Claude 4At the same time, Sonnet 4 was launched, featuring highly integrated APIs and a strong focus on enterprise-level application scenarios.
4 major upgrades
Claude 4 Officially positioned as a "long-duration autonomous AI agent," it can execute tasks for hours on end, autonomously invoke tools, and optimize coding, inference, file memory, and batch processing capabilities. The two main models are:
- Claude 4 OpusIt boasts the highest computational and reasoning capabilities, and performs best in coding tasks.
- Claude 4 SonnetHigh efficiency, suitable for intensive operations and high-volume enterprise applications.
CLAUDE 4 Features and Core Technologies
Autonomous Task Processing and Extended Thinking
Claude 4 Opus It can perform complex and coherent tasks for extended periods, such as programming, game strategy generation, and multi-step reasoning. Research shows that its sustained operation capability significantly surpasses that of its predecessor (Sonnet 3.7), and it has been used by Japanese companies and open-source teams for automated coding for up to 7 hours.
Coding and Tool Integration
Code processing capabilities This is one of Claude's strengths. The Opus 4 achieved an excellent performance of 79% in the SWE-bench test (GPT-4 Turbo is about 76%), and can automatically repair programs, understand large code projects, and support multi-language SDKs and GitHub Actions integration.
Memory and Multi-session Context
Unrivaled in its class, Claude 4 supports...“"Memory Files"This feature allows for the persistent storage of task progress and important knowledge snippets. The Documents API enables cross-session file reading and writing, making it suitable for multi-step, long-running tasks such as product planning and data report generation.
Multimodal input and image analysis
Claude 4 It has powerful image recognition capabilities and can upload images or files for analysis and summarization, including charts, flowcharts, etc. Application scenarios cover daily life, professional financial analysis, design review, teaching, etc.
Security mechanisms and privacy design
Anthropic employs the ASL-3 security evaluation standard, undergoing comprehensive review and testing before release to significantly reduce "illusions," data leaks, and unintended behaviors. Furthermore, a strict user data isolation policy ensures that chat content is not used in training data, guaranteeing privacy and security.
