In the constantly evolving AI landscape, competition between OpenAI and Anthropic represents a clash of visions.
While ChatGPT 5 focuses on creativity and productivity, Claude 3 was built with a different goal: creating an AI that is safer, more responsible, and more ethical.
Behind its development lies Anthropic’s philosophy—founded by former OpenAI researchers—aimed at building “constitutional” AI systems: models that learn to reason by following predefined moral rules, not just data.
In 2025, Claude 3 becomes a reference point for a new way of thinking about AI: intelligent, yet aware of its own limits.
Anthropic defines its mission as building “AI aligned with human values.”
The core idea behind the Claude project is that artificial intelligence should not only answer, but also evaluate the impact of its responses.
Claude 3 includes an “Ethical Constitution” system: a set of principles inspired by human rights, transparency, and respect for differing viewpoints.
Every output is filtered through a series of internal reasoning steps, allowing the model to decide whether a response is appropriate.
➡️ In practice, Claude 3 isn’t just “intelligent”: it is self-aware of the consequences of its words.
From a technical standpoint, Claude 3 is based on a multimodal model capable of analyzing text, images, and complex documents.
It can read PDF files, charts, slides, and even source code, summarizing information in real time.
Its contextual memory has been expanded up to 200,000 tokens—roughly the equivalent of an entire university textbook—allowing the model to maintain logical consistency in very long conversations.
Its “transparent chain-of-thought” approach also enables it to explain step by step how it reached a conclusion—an uncommon feature in generative AI.
While ChatGPT 5 aims to become a creative and productive copilot, Claude 3 focuses on deep understanding and ethical reasoning.
Features Claude 3 ChatGPT 5
Main focus Logical and ethical reasoning Creativity and productivity
Multimodality Text + images + documents Text + voice + video
Data security High, with local encryption Standard cloud
Memory Long (200k tokens) Contextual and dynamic
Purpose Thoughtful and neutral decisions Fast and adaptive responses
👉 The challenge is no longer only about power, but about responsibility in AI.
Claude 3 uses a “constitutional AI” approach, where training is guided by explicit ethical principles.
This drastically reduces bias, toxic content, and manipulative responses.
All interactions are processed in a private sandbox mode, without storing personal data.
Anthropic also introduced a human-assisted verification system, allowing enterprise users to check the ethical consistency of generated answers.
According to the company itself: “Security is not an additional feature, but the foundation of the entire Claude project.”
Claude 3 is used today in:
publishing and journalism, for fact-checking and summarizing complex sources;
academic research, thanks to its ability to read scientific documents and generate coherent analyses;
tech companies, integrating it into decision-making workflows to ensure neutral and transparent outputs;
education, as a learning assistant for critical thinking and ethical support in academic writing.
In this sense, Claude 3 does not replace humans: it supports them as a digital mentor, ensuring accuracy and responsibility.
Anthropic’s next expected evolution is creating a model capable of understanding human emotions.
Claude 4, already in development, will introduce a level of artificial empathy able to recognize tone, intention, and moral context.
The goal is an AI that not only answers, but also understands when it is appropriate to respond—and how.
The final vision is a system that can cooperate with humans—not to replace them, but to reason together in a constructive way.
