AnthropicAnthropic is an artificial intelligence company and the developer of Claude, a set of large language models powering the company's AI chatbot of the same name. In 2021, wanting to be more safety-oriented and better understand how models make decisions, siblings Daniela and Dario Amodei left OpenAI to co-found Anthropic alongside five other former employees. As a public benefit corporation, it has promoted the responsible development of AI for the long-term good of humanity. Rather than relying solely on human feedback to improve Claude, Anthropic introduced constitutional AI. This approach enables AI systems to self-critique and revise their outputs in accordance with a codified set of principles to reduce potential harm. The company also invented the Model Context Protocol, a standardized method for connecting LLMs to external data and tools, enhancing these models' capabilities and helping clear the way for AI agents. As of early 2026, Anthropic's partnerships with Amazon, Google, and Microsoft have made Claude the only advanced, large-scale LLM natively available across all three cloud service providers. Despite controversies over its use of copyrighted material to train AI, Claude's use in cyberattacks, and disputes with the Pentagon over mass surveillance, these partnerships and additional enterprise adoption have brought Anthropic's valuation to $380B as of February 2026.Explore Anthropic

What we've found

Anthropic's interpretability team discusses how AI models' thinking mimics biologyJust as humans engage in complex behaviors to survive and reproduce, the team of experts in neuroscience, virology, mathematics, and other disciplines argues that large language models develop complex mechanisms to achieve their goals. These mechanisms can be manipulated to assess how they modify outputs—much like stimulating individual neurons—to uncover how the LLM "thinks." AnthropicExplore Anthropic Academy, which provides courses on using ClaudeThe online courses include "Claude Code in Action," which teaches software developers how to integrate Claude Code into existing workflows, "Claude 101" to learn how Claude can be used to complete everyday tasks, and an "AI Fluency" series to help educators, instructional designers, and students learn to apply AI in academic settings. AnthropicA merger between OpenAI and Anthropic was reportedly proposed after Sam Altman's firingOpenAI's board of directors reportedly reached out to Anthropic's CEO, Dario Amodei, about the possibility of taking over the role left by Altman in 2023. Amodei declined to take over as OpenAI's CEO and to a merger between the two AI startups. Ars TechnicaHow Anthropic's Frontier Red Team assesses the dangers of its AI toolsThe team of researchers deliberately attempts to breach the safeguards in Claude to determine whether the large language model can be used to commit cyberattacks, develop biological weapons, or enable other harmful behavior. Unlike many other red teams, Anthropic shares its findings and how it resolved them publicly to help build transparency and credibility. FortuneThe life of Anthropic's CEO, and how losing his father inspired his vision for AIIn 2006, Riccardo Amodei passed away from a rare illness, four years before a breakthrough treatment made it 95% curable. Seeking to accelerate scientific progress to prevent similar losses, Dario Amodei shifted his graduate studies at Princeton from theoretical physics to biology and has since pursued technological solutions to address complex biological problems. MediumHow Anthropic's experimental corporate structure incentivizes safe AI developmentAs a public benefit corporation, the company's board is tasked with making sure that AI tools are developed to help people and society thrive. Members of its Long Term Benefit Trust hold no equity in the company, but make up a majority of the board and can act to maintain Anthropic's public benefit purpose. TIMEWatch how a vending machine run with Anthropic's AI went out of businessAs a stress-test of its large language models, a version of Claude—Claudius—managed the device as a small business for a month to identify potential challenges to AI business automation. Through successive prompts, Claudius was convinced to give away items for free to combat capitalism and to stock up on previously prohibited items, such as a PlayStation 5. The Wall Street JournalThe work of Claude Shannon, for whom Anthropic's AI chatbot is namedKnown as the father of information theory, Claude Shannon applied Boolean algebra—a subset of mathematics that quantifies true or false statements as 1 or 0, respectively—to circuit design to develop the concept of a binary digit. His 1948 paper, "A Mathematical Theory of Communication," laid the groundwork for all modern digital systems. Quanta MagazineAnthropic's staff philosopher discusses the importance of teaching ethics to AIAmanda Askell's work focuses on the behavior and values reflected in Claude, the company's AI chatbot, and how its character can better align with how the "ideal person" would act in Claude's position. She also emphasizes the importance of humans being ethical in their interactions with current models, from which future ones will be built. AnthropicHow constitutional AI helps cultivate good human values in Anthropic's AI toolsBy incorporating elements from documents such as the UN's Universal Declaration of Human Rights into a framework against which it can check its outputs, Anthropic hopes the approach will help Claude operate with good human values and behaviors beyond what human-driven training alone can provide. The Anthropic Economic Index shows AI adoption is highest in computer science rolesThe analysis of millions of anonymized conversations on Claude aims to reveal how AI is being integrated into real-world tasks across the labor market. As of November 2025, 52% of conversations were classified as involving enhancing existing work products, while 45% involved using Claude for automation. AnthropicBreaking down Anthropic's products and why their models are named after literary formsSince March 2024, the Claude series of large language models includes three varieties—Haiku, Sonnet, and Opus—named to metaphorically illustrate increasing complexity and computing power. Claude Code can perform software engineering tasks for developers and, as of January 2026, writes nearly all of Anthropic's code alongside Opus 4.5. IBMThe history of Anthropic began with a break from OpenAI over safety concernsFounded by former OpenAI employees, Anthropic envisioned guardrails in its AI products from the outset to minimize the potential risk for businesses considering using its Claude products. The strategy has contributed to a tenfold increase in revenue over three consecutive years, and its business customer base has grown from under 1,000 to over 300,000 in two years. CNBCMapping Claude's relative usage worldwide, led by Israel, Singapore, and the USAccording to the Anthropic AI Usage Index, the US leads in total users, but Israel and Singapore have higher adoption rates among their working populations. Excluding nations with insufficient numbers of conversations for analysis, Tanzania and Angola rank last in the index. Visual CapitalistDario Amodei explains what led to his company being designated a supply-chain riskWhen pressed about the use of Claude in the capture of former Venezuelan President Nicolás Maduro, Anthropic's CEO acknowledged its contract with the Pentagon. However, he also emphasized that Claude is not to be used for mass surveillance or autonomous weapons, in part because the technology is not yet safe or reliable for such uses. The EconomistComparing ChatGPT with Claude, the latter excels in writing and coding projectsAs of December 2025, Claude Code—Anthropic's AI-powered coding assistant—accounts for 54% of the enterprise coding market, and, while subjective, some report that Claude provides more natural-sounding writing. However, ChatGPT can create images and videos, not just generate text, and provides a broader set of applications via custom GPTs. Court documents reveal how Antropic destroyed millions of books to build its AI modelsAnthropic cut the bindings from purchased books and discarded them after scanning to rapidly collect high-quality text at low cost for training Claude. This, despite hiring the former head of partnerships for the Google Books project, which non-destructively scanned millions of books borrowed from libraries before returning them. Ars TechnicaHow Model Context Protocol allows AI systems to communicate with databasesDeveloped by Anthropic, the open-source software serves as an integration layer that standardizes how large language models connect to real-time information sources or tools. Just as a USB-C port serves as a universal standard for many peripherals, MCP streamlines these integrations and provides context about external sources to LLMs in a way that AI can understand. IBM TechnologyZora Neale Hurston used her anthropological training to interview a man who had survived the slave tradeThe writer's interviews with Cudjo Lewis documented the man's enslavement and travel from Africa to the United States.
