Anthropic presents Claude 4, the revolutionary code model of the moment

In the ever-evolving landscape of artificial intelligence, a new shining star has emerged: Claude 4, developed by the startup Anthropic. Launched on May 22, this model comes in two distinct versions, namely Claude 4 Opus and Claude 4 Sonnet, each addressing specific needs in the field of software development. Anthropic’s code model claims the leading edge in efficiency and automation of programming tasks. How will this innovation transform our digital future and our approach to development? Let’s explore the capabilities and promises of Claude 4.

The Impressive Features of Claude 4

Claude 4 has already generated considerable interest thanks to its exceptional capabilities. The Opus version, in particular, was designed to handle complex tasks while offering the ability to work autonomously for several hours. This model goes beyond the simple capabilities of a classic chatbot to assert itself as a true development agent. Revolutionary Autonomy

Claude 4 Opus is designed to perform complex tasks thanks to its advanced reasoning. Its battery life of several hours allows it to adapt to multiple contexts without human intervention. This feature is crucial in a development environment where response time and efficiency are paramount. Here are some examples of its capabilities:

Use of external tools for web search.

• Real-time code execution.
• Interaction with MCP server connectors.
• Claude 4 Sonnet for everyday use

In contrast, the Sonnet version is closer to a traditional virtual assistant. However, it also excels in code generation. Claude 4 Sonnet’s performance surpasses that of its predecessor, 3.7 Sonnet. This improvement is mainly due to its better ability to follow precise instructions and clearer code generation.

Model

In terms of performance evaluation, Claude 4 Opus and Sonnet stand out in specific benchmarks related to software engineering. Notably, Sonnet achieved a score of 80.2% on the verified SWE-bench, a test measuring the ability to solve real-world development problems. This score is particularly impressive compared to other refined models from OpenAI and Gemini.

Benchmark and Results

The scores of the various models speak for themselves:

Model

From an economic perspective, the prices of Claude 4 Opus and Sonnet remain relatively high compared to other models on the market. Opus, for example, is priced at $15 for one million input tokens and $75 for output. Claude 4 Sonnet, on the other hand, is available at $3 for one million input tokens and $15 for output. This price, while substantial, is justified by the advanced capabilities of these models. They effectively meet the growing need for automation and innovation in software development.
