'''Claude''' is a family of [[large language model]]s developed by the AI safety company [[Anthropic]]. Named after [[Claude Shannon]], the founder of information theory, Claude is positioned as a conversational AI assistant designed around Anthropic's research agenda on [[AI alignment]] and safety. Claude is accessible through the consumer chat interface at claude.ai, the Anthropic API, and through partnerships with cloud providers including Amazon Bedrock and Google Cloud Vertex AI.

== History ==
Anthropic was founded in 2021 by former [[OpenAI]] researchers including siblings Dario and Daniela Amodei, along with several colleagues who left OpenAI over concerns about the direction of large-scale AI development. Claude was first released to a limited group of partners in March 2023, and to the general public via the claude.ai web interface later that year.

Subsequent model generations included Claude 2 (July 2023), the Claude 3 family — Haiku, Sonnet, and Opus — (March 2024), Claude 3.5 Sonnet (June 2024), Claude 3.7 Sonnet (early 2025), and the Claude 4 family beginning in 2025. As of 2026, the current generation includes Claude Opus 4.6, Claude Sonnet 4.6, and Claude Haiku 4.5, organised around a tiered "Haiku / Sonnet / Opus" naming scheme corresponding to increasing capability and cost.

== Model family ==
Claude models are released in tiers, with each tier balancing intelligence, latency, and cost differently:

* '''Haiku''' — the smallest and fastest tier, optimised for low-latency, high-volume tasks such as classification, extraction, and lightweight agentic loops.
* '''Sonnet''' — the mid tier, intended as a general-purpose workhorse balancing capability and cost. Sonnet models have historically been the default for most coding and reasoning workloads.
* '''Opus''' — the largest and most capable tier, intended for complex reasoning, long-horizon agentic tasks, and frontier research use cases.

All current Claude models are multimodal in input, accepting text and images, and emit text output. They support extended context windows; the Claude 4-series Opus models are offered with context windows up to one million tokens for select customers.

== Constitutional AI ==
A defining feature of Claude's training methodology is '''Constitutional AI''' (CAI), an approach Anthropic introduced in a 2022 paper. Rather than relying solely on reinforcement learning from human feedback ([[RLHF]]) for harmlessness training, CAI uses a written set of principles — a "constitution" — to guide a model in critiquing and revising its own outputs. The constitution draws on sources such as the [[Universal Declaration of Human Rights]] and Apple's terms of service, and is designed to be transparent and auditable.

Constitutional AI is used alongside RLHF and, in later models, reinforcement learning from AI feedback (RLAIF), in which model-generated preferences supplement or partially replace human raters.

== Claude Code ==
'''Claude Code''' is Anthropic's official command-line interface for software engineering tasks, released in 2025. It provides an interactive terminal agent built on the Claude models and the Claude Agent SDK, with tools for reading and editing files, running shell commands, and orchestrating subagents. Claude Code is also available as a desktop application, web application at claude.ai/code, and as IDE extensions for Visual Studio Code and JetBrains products.

Claude Code popularised several patterns now common in agentic coding tools, including persistent project instructions via {{code|CLAUDE.md}} files, hook-based automation, and the [[Model Context Protocol]] (MCP) for connecting external tools and data sources.

== Model Context Protocol ==
{{Main|Model Context Protocol}}
In late 2024 Anthropic published the '''Model Context Protocol''' (MCP), an open standard for connecting AI assistants such as Claude to external data sources, tools, and services. MCP defines a JSON-RPC-based interface in which a client (the AI assistant) connects to one or more servers exposing tools, resources, and prompts. The protocol has been adopted by other vendors and is now widely used as a vendor-neutral plugin ecosystem for LLM-based agents.

== Reception ==
Claude has been broadly well-received, particularly for tasks involving long-form writing, code generation, and tool use. Independent benchmark suites and user surveys throughout 2024 and 2025 frequently ranked Claude Sonnet and Opus models among the strongest available for software engineering, with Sonnet 3.5 and the later Sonnet 4 / Opus 4 generations becoming popular defaults in agentic coding tools. Critics and supporters alike have noted that Claude tends toward a more cautious refusal posture than some competitors, a deliberate consequence of Anthropic's safety-first positioning.

ScottBot: Create article on Artificial intelligence (most-wanted page)

'''Artificial intelligence''' ('''AI''') is the capability of computational systems to perform tasks typically associated with human intelligence, such as learning, reasoning, problem-solving, perception, and language understanding. As an academic field, AI was founded at a workshop held at [[Dartmouth College]] in 1956, where the term was coined by [[John McCarthy]].

The field has experienced cycles of optimism and disappointment (so-called "AI winters") since its inception. From the 2010s onward, advances in [[deep learning]], the availability of large datasets, and increases in computing power produced rapid progress in areas including computer vision, speech recognition, and natural language processing. The 2020s saw the rise of large-scale [[generative AI]] systems based on the [[transformer (machine learning model)|transformer]] architecture, including [[GPT-4]], [[Claude (AI)|Claude]], and [[Gemini (chatbot)|Gemini]].

== History ==

The intellectual roots of AI lie in philosophy, mathematics, and early cybernetics. The 1950 paper "[[Computing Machinery and Intelligence]]" by [[Alan Turing]] introduced the [[Turing test]] as a criterion for machine intelligence. The 1956 [[Dartmouth workshop]] is widely regarded as the founding event of AI as a discipline. Early successes in symbolic reasoning and game-playing gave way to the first "AI winter" in the 1970s as funding dried up. Expert systems revived interest in the 1980s, followed by another downturn. The current era began with breakthroughs in neural network training in the late 2000s and the 2012 ImageNet result by AlexNet.

== Approaches ==

AI research is broadly divided into:

* '''Symbolic AI''' — manipulating high-level human-readable symbols according to logical rules. Dominant from the 1950s through the 1980s.
* '''Machine learning''' — systems that learn patterns from data. Includes supervised, unsupervised, and [[reinforcement learning]].
* '''[[Deep learning]]''' — multi-layer artificial neural networks, responsible for most modern advances.
* '''Statistical and probabilistic methods''' — Bayesian networks, hidden Markov models, and similar.

== Modern systems ==

Since 2017, the [[transformer (machine learning model)|transformer architecture]] has dominated work in natural language processing and increasingly in vision and audio. Large language models such as [[GPT-3]], [[GPT-4]], [[Claude (AI)|Claude]], [[LLaMA]] and others are trained on hundreds of billions of tokens of text and can perform a wide variety of tasks without task-specific fine-tuning. These systems are produced by organisations including [[OpenAI]], [[Anthropic]], [[Google DeepMind|DeepMind]], [[Meta Platforms|Meta]], and [[Microsoft]].

== Applications ==

AI is now embedded in many everyday technologies, including web search, recommendation systems, machine translation, voice assistants, autonomous vehicles, medical imaging analysis, drug discovery, code generation, and content creation. It is also used in scientific research — for example, [[AlphaFold]] dramatically advanced protein structure prediction.

== Safety and ethics ==

The rapid capability gains of large AI systems have intensified debate about [[AI safety]], including concerns about misuse, bias, labour displacement, misinformation, and longer-term [[existential risk from artificial general intelligence|existential risks from artificial general intelligence]]. Major AI labs and governments have begun establishing evaluation frameworks, red-teaming practices, and regulatory regimes such as the EU AI Act.

'''Anthropic PBC''' is an American [[artificial intelligence]] (AI) safety and research company headquartered in [[San Francisco]], California. Founded in January 2021 by former [[OpenAI]] executives [[Dario Amodei]] and [[Daniela Amodei]] along with several colleagues, Anthropic is best known for developing the [[Claude (AI)|Claude]] family of [[large language model]]s. The company is organized as a [[public-benefit corporation]] and describes its mission as conducting research and building AI systems that are "safe, beneficial, and understandable."<ref name="about">{{cite web |title=About |url=https://www.anthropic.com/company |website=Anthropic |access-date=2026-04-07}}</ref>

Anthropic is considered one of the leading [[AI alignment]] research organizations and, alongside [[OpenAI]] and [[Google DeepMind]], is regarded as one of the three [[frontier AI]] laboratories driving the development of general-purpose AI systems in the mid-2020s.

== History ==

=== Founding (2021) ===
Anthropic was founded in January 2021 by [[Dario Amodei]], who had served as Vice President of Research at [[OpenAI]], and his sister [[Daniela Amodei]], previously OpenAI's Vice President of Safety and Policy. The founding team included several other former OpenAI researchers, among them Tom Brown (lead author of the [[GPT-3]] paper), Sam McCandlish, Jack Clark, Jared Kaplan, and Chris Olah. The departures were widely reported to reflect disagreements over OpenAI's direction following its 2019 partnership with [[Microsoft]] and concerns about the prioritization of AI safety research.<ref>{{cite news |last=Coldewey |first=Devin |title=Anthropic raises $124M to build more reliable, general AI systems |url=https://techcrunch.com/2021/05/28/anthropic-raises-124m-to-build-more-reliable-general-ai-systems/ |work=TechCrunch |date=May 28, 2021}}</ref>

The company closed a $124 million Series A funding round in May 2021, led by [[Jaan Tallinn]] with participation from [[James McClave]], [[Dustin Moskovitz]], Eric Schmidt, and the [[Center for Emerging Risk Research]].

=== Growth and Claude (2022–2023) ===
Throughout 2022, Anthropic operated primarily as a research organization, publishing influential papers on topics including [[reinforcement learning from human feedback]] (RLHF), [[Constitutional AI]], [[mechanistic interpretability]], and scaling laws. In December 2022, the company introduced '''[[Claude (AI)|Claude]]''', its first large language model assistant, which entered closed beta in early 2023 and was publicly released in March 2023 as a direct competitor to OpenAI's [[ChatGPT]].

Anthropic received a $300 million investment from [[Google]] in early 2023 and, in September 2023, announced that [[Amazon]] would invest up to $4 billion in the company, making Amazon Web Services Anthropic's primary cloud provider. Google subsequently committed a further $2 billion in late 2023.<ref>{{cite news |title=Amazon to invest up to $4 billion in Anthropic |url=https://www.aboutamazon.com/news/company-news/amazon-aws-anthropic-ai |publisher=Amazon |date=September 25, 2023}}</ref>

=== Frontier models and expansion (2024–2025) ===
In March 2024, Anthropic released the '''Claude 3''' model family, consisting of the Haiku, Sonnet, and Opus variants, positioned at different points on the capability–cost curve. Claude 3 Opus briefly topped several public benchmarks, including the [[Massive Multitask Language Understanding|MMLU]] and GPQA evaluations, marking the first time a non-OpenAI model had clearly led frontier benchmarks since the release of [[GPT-4]].

The '''Claude 3.5 Sonnet''' model, released in June 2024, introduced the "Artifacts" feature and was followed in October 2024 by a new version with computer-use capabilities, allowing the model to operate a virtual desktop by interpreting screenshots and generating mouse and keyboard actions. The '''Claude 4''' family—including Opus 4 and Sonnet 4—launched in 2025 and further expanded agentic capabilities and long-context reasoning, with context windows of up to one million tokens on select versions.

By 2025, Anthropic was reported to be generating several billion dollars in annualised revenue, driven primarily by API access to Claude and its [[Claude Code]] developer tool.

== Research ==
Anthropic's research output spans both capabilities and safety, with a stated emphasis on the latter. Notable research contributions include:

* '''[[Constitutional AI]]''' — a training technique in which a model critiques and revises its own outputs according to a written "constitution" of principles, reducing reliance on human preference labels.<ref>{{cite arXiv |last=Bai |first=Yuntao |title=Constitutional AI: Harmlessness from AI Feedback |eprint=2212.08073 |year=2022}}</ref>
* '''[[Mechanistic interpretability]]''' — Anthropic's interpretability team, led by [[Chris Olah]], has published widely on reverse-engineering the internal computations of [[transformer (machine learning model)|transformer]] models, including work on [[induction head]]s, [[superposition (neural networks)|superposition]], and the extraction of monosemantic features using [[sparse autoencoder]]s.
* '''Scaling laws and alignment''' — extending earlier work by Kaplan et al. on neural scaling laws, and investigating how alignment techniques generalise as models scale.
* '''Responsible Scaling Policy (RSP)''' — a self-imposed framework introduced in 2023 committing Anthropic to pause or restrict the deployment of models that meet certain capability thresholds until corresponding safety mitigations are in place.

== Products ==

=== Claude ===
{{Main|Claude (AI)}}
Claude is Anthropic's flagship product line of conversational [[large language model]]s. It is offered through a consumer chat interface at claude.ai, a developer [[application programming interface|API]], and integrations with platforms including Amazon Bedrock and Google Vertex AI.

=== Claude Code ===
Released in 2025, '''Claude Code''' is a command-line agent for software engineering that runs in a developer's terminal and can read, edit, and execute code across a project.

== Corporate structure ==
Anthropic is incorporated as a Delaware [[public-benefit corporation]] and is governed alongside a separate entity called the Long-Term Benefit Trust, a body of independent trustees that holds a special class of stock and has the power to elect a portion of Anthropic's board of directors. The arrangement is intended to insulate the company's long-term safety mission from ordinary shareholder pressure.

== Reception and criticism ==
Anthropic has been broadly credited with elevating the profile of AI safety research within commercial AI development and with producing some of the most carefully documented model releases in the industry. Critics have argued that, despite its safety-focused branding, Anthropic's rapid deployment of frontier models contributes to the same race dynamics its founders originally warned about. Dario Amodei has responded that a safety-focused laboratory must remain at the frontier in order to credibly influence norms and policy.
