Claude AI is a synthetic intelligence mannequin that may act as a chatbot and an AI assistant, very like ChatGPT and Google’s Gemini. Named after Claude E. Shannon, generally known as the “father of information theory,” Claude was designed to help with writing, coding, buyer assist and knowledge retrieval. Claude was developed by Anthropic, a San Francisco-based firm based in 2021 by former OpenAI staff specializing in AI security and analysis. Dario Amodei, the co-founder and CEO of Anthropic, had served as vp of analysis at OpenAI. His sister, Daniela Amodei, serves as Anthropic’s president.Anthropic has drawn vital funding from outstanding tech gamers. Since 2023, Amazon has invested $8 billion within the firm. As a part of the settlement, Anthropic has dedicated to utilizing Amazon Web Services as its main cloud supplier and making its AI fashions accessible to AWS prospects. The 2024 deal contains plans to increase using Amazon’s AI chips for coaching and operating Anthropic’s massive language fashions. Google initially invested $500 million and plans to take a position one other $1.5 billion sooner or later.So what can Claude do now? Here’s the whole lot it is advisable know, together with the fashions, plans, pricing and newest updates.How Claude AI worksClaude AI is a flexible device able to answering questions, producing artistic content material like tales and poems, translating languages, transcribing and analyzing photographs, writing code, summarizing textual content and interesting folks in pure, interactive conversations. It is accessible on desktop through net browsers and iOS and Android apps.Claude makes use of massive language fashions educated on an enormous dataset of textual content and code to know and generate human-like language. Screenshot by Barbara Pazur/CNETUntil lately, and in contrast to different chatbots similar to OpenAI’s ChatGPT, Gemini, Copilot and Perplexity, certainly one of Claude’s greatest flaws was that it could not entry real-time web or retrieve info from net hyperlinks. Instead, generated responses based mostly solely on the info it was educated on. Each Claude mannequin has a particular information deadline. For instance, Claude 4 Opus and 4 Sonet had been educated on information up till March 2025 and Claude 3.5 Haiku till July 2024. Anthropic frequently up to date Claude’s information to reinforce its capabilities.Starting in March 2025, Claude lastly obtained entry to the web by means of a “Web Search” function. Initially, it was accessible as a paid preview for folks within the US, after which it expanded globally in May 2025 to all Claude plans and is now accessible on all fashions.Knowledge cutoff nonetheless issues as a result of the net search does not change the coaching information, however slightly dietary supplements it for extra up-to-date and related responses. Claude AI: Key featuresConversational adaptability is certainly one of its coolest options. Claude AI adjusts its tone and depth based mostly on consumer queries. Its means to ask clarifying questions and keep context over prolonged exchanges makes it helpful for each informal and sophisticated conversations. That is likely one of the the explanation why our editors named it CNET’s greatest chatbot of 2025.The platform additionally presents APIs which you could combine into numerous instruments and workflows.In November 2024, Anthropic launched the Model Context Protocol to its Claude desktop app, enabling the chatbot to browse the web and handle information in your pc. This open-source protocol permits Claude to work together with numerous platforms and streamline integration by eliminating the necessity for customized code. Screenshot by Barbara Pazur/CNETAnthropic’s new Integrations function allows Claude to attach seamlessly with exterior apps through the Model Context Protocol, giving it wealthy context throughout your instruments. It can automate duties in Jira and Zapier or summarize Confluence pages — all by means of conversational prompts.Another function, Advanced Research, boosts Claude’s analysis by diving deep into each inside and exterior information. It can spend anyplace from 5 to 45 minutes per question and produce thorough, citation-backed studies. It now faucets into net searches, your personal paperwork and built-in apps like Google Workspace, providing you with sooner, clear solutions that beforehand may have taken hours to assemble manually.Claude fashions definedThe preliminary model of Claude was launched in March 2023, adopted by Claude 2 in July 2023, permitting for extra in depth enter processing. Then, in March 2024, Anthropic launched Claude 3, comprising three fashions: Haiku, Sonnet, and Opus, every optimized for various efficiency wants. Haiku is supposed for fast and easy duties the place velocity issues most. Sonnet balances velocity and energy for on a regular basis use, and Opus handles superior duties like arithmetic, coding and logical reasoning. In October 2024, Haiku and Sonnet had been upgraded to 3.5 fashions. By May 2025, each Opus and Sonnet fashions had been upgraded to model 4. With the discharge of the Claude 3.5 Haiku mannequin, Anthropic claims it “matches the performance of Claude 3 Opus” and remains to be the quickest mannequin. Anthropic additionally acknowledged within the weblog that Opus 4 is “the world’s best coding model,” and its most clever one. Sonnet 4 delivers balanced efficiency, enhanced reasoning and extra correct responses to your directions..In October 2024, Anthropic’s improved model of Claude 3.5 launched a beta function known as pc use. Claude may carry out duties similar to transferring the cursor, clicking buttons and typing textual content, successfully mimicking human-computer interactions. Claude at present helps PDF, DOCX, CSV, TXT, HTML, ODT, RTF, EPUB, JSON and XLSX. However, it has file limits inside chat uploads, similar to 30MB per file, as much as 20 information per chat and visible evaluation for PDFs beneath 100 pages. For detailed limits, test Anthropic’s assist web page.Claude at present helps PDF, DOCX, CSV, TXT, HTML, ODT, RTF, EPUB, JSON and XLSX. However, it has file limits inside chat uploads, similar to 30MB per file, as much as 20 information per chat and visible evaluation for PDFs beneath 100 pages. For detailed limits, test Anthropic’s assist web page.Claude’s ‘constitutional AI’ methodClaude’s distinguishing function in comparison with different generative AI fashions is its give attention to “ethical” alignment and secure interactions. On Nov. 11, 2024, Dario Amodei joined Lex Fridman for a 2-and-a-half-hour podcast to debate AI. During the dialog, he stated, “It is incredibly unproductive to try and argue with someone else’s vision.” So, he based his personal firm to display that accountable AI implementation may be each moral and worthwhile.The “constitutional AI” framework aligns Claude’s conduct with human values. This method makes use of a predefined set of rules, or “constitution,” to information the AI’s responses, lowering the chance of dangerous or biased outputs whereas making certain its responses stay helpful and coherent. The structure contains tips from paperwork just like the UN’s Universal Declaration of Human Rights.Afraz Jaffri, a senior director analyst at Gartner, advised CNET the transparency round Anthropic’s method “does provide a certain degree of confidence in usage of the model in environments where responses need to reach a high threshold of safety, such as in educational settings.”However, Jaffri cautioned that Claude customers should not rely solely on Anthropic’s built-in safeguards, and really helpful utilizing exterior guardrail instruments — like these supplied by different AI suppliers — to observe prompts and responses as an added layer of safety. “As recently shown by their own research, even with ethical alignment, their Opus 4 model exhibited uncharacteristic behaviour by blackmailing an engineer who had threatened to turn the model off,” Jaffri stated.He added that restricted transparency round Claude’s coaching course of means further security checks are nonetheless mandatory. “Every possible scenario cannot be fully covered in testing,” he advised CNET, noting that programs like Computer Use and Claude Code want extra guardrails in place to offset sudden conduct.Claude pricing and plansAnthropic presents a wide range of pricing plans. There is a free possibility if you wish to check Claude with out dedication. For these in search of enhanced capabilities for particular person customers, the Claude Pro subscription is accessible at $20 monthly.
