Claude

Claude, developed by the American company Anthropic, is a major player in the field of artificial intelligence, particularly recognized for its large-scale language models. Founded by siblings Dario and Daniela Amodei, Anthropic quickly distinguished itself with its focus on AI safety and ethics, introducing the concept of constitutional AI to ensure model alignment with humanistic values.

Areas of Expertise and Key Achievements

Claude positions itself as a powerful tool for coding, complex reasoning, and agent-based automation. The Claude Opus 4 and Claude Sonnet 4 models are a testament to this expertise, outperforming renowned competitors such as GPT-4 and Gemini 2.5 in terms of performance on real-world software engineering tasks. Claude Opus 4, for example, is praised for its ability to operate for several hours without performance degradation, making it ideal for multi-agent architectures.

Claude 3.7 Sonnet, the first hybrid reasoning model on the market, combines speed and depth of analysis, allowing for extensive user-visible reflection. This innovation provides granular control to users via Anthropic's API, enabling them to set a reflection budget in terms of tokens, thus optimizing the balance between response quality and operational costs.

Recent Contributions and Notable Projects

Anthropic recently unveiled Claude 4, which includes Claude Opus 4 and Claude Sonnet 4, designed for advanced coding tasks and complex reasoning. These models incorporate features such as "extended thinking," allowing the AI to dynamically switch between reasoning and tool usage, like web search during a task. Claude Code, an autonomous development "copilot," is also available, offering native integrations for popular development environments such as VS Code and JetBrains.

In May 2025, Anthropic unveiled the Model Context Protocol (MCP), an innovative open-source standard allowing AI models to connect to existing data systems. This initiative aims to overcome the limitations of AI assistants isolated from critical data, thereby facilitating their integration into diverse professional environments.

Position in the Technological Ecosystem

Claude is considered a leader in the field of language models, notably due to its ability to compete with giants such as OpenAI and Google DeepMind. The Claude 4 model surpasses GPT-4 and Gemini 2.5 on software engineering benchmarks, reinforcing Anthropic's reputation as a developer of cutting-edge AI technologies. Furthermore, the company is actively committed to model transparency and safety, as evidenced by the publication of system prompts and system cards detailing evaluation methods and risk mitigation strategies.

Recent Developments and News

Claude was recently mentioned in the context of the European Union's AI Act as a large-scale model presenting potential systemic risks. The code of good practices for general-purpose AI models, developed by the European Commission, emphasizes transparency, copyright, and safety, with specific recommendations for models like Claude.

Meanwhile, Anthropic was involved in a legal case concerning the use of pirated books for training its AI. Although the company was found guilty of retaining pirated books, it was cleared of using them to train its AI, with the judge ruling that the use of legally acquired books constituted fair use.

In conclusion, Claude represents a significant advancement in the field of AI language models, with substantial contributions to research and technological development. Its position in the technological ecosystem is bolstered by its commitment to safety, transparency, and ethics, elements that will remain crucial as AI technologies continue to evolve.
