Claude is Anthropic's family of AI assistant models, used by roughly 245 million monthly active users across its chat, API, and enterprise surfaces. Haiku, Sonnet, and Opus tiers cover chat, coding, and long-document work, and Max plans add a 1-million-token context window for full-codebase or full-book prompts.
About Claude
Claude is Anthropic's family of AI assistants, available through a web app, developer API, and enterprise deployments. Anthropic released Claude Sonnet 5 on June 30, 2026 as the most agentic model in the Sonnet line, and Claude Opus 5 followed on July 24, 2026 as the new flagship model. Anthropic also launched Claude Science, an auditable AI workbench designed for conducting all stages of scientific research. Scientists can analyze literature, perform multi-step research, generate detailed artifacts, and develop manuscripts for peer review publication within a single, transparent interface that prioritizes interpretability and auditability. The platform serves researchers, developers, and enterprises. API users span machine learning engineers building production systems, research institutions evaluating frontier models, and Fortune 500 companies implementing autonomous agents. Claude is available on the web, via API, and through enterprise deployments on AWS, Google Cloud, and Microsoft Azure. Anthropic was founded in 2021 by siblings Dario Amodei (CEO) and Daniela Amodei (President), both former OpenAI executives, and is headquartered in San Francisco. The company raised a $30 billion Series G round in February 2026 at a $380 billion valuation, with total funding topping $40 billion from backers including Google, Amazon, and Salesforce Ventures.
Pricing
Free tier: limited daily messages, Sonnet 5 as the default model. Pro: $20/month for web access with priority Opus access. Max 5x: $100/month; Max 20x: $200/month; both add a 1-million-token context window. Team Standard: $25/seat/month; Team Premium: $125/seat/month with Claude Code CLI included. Enterprise: custom pricing with SSO and spend controls. Developer API: Sonnet 5 at an introductory $2/M input and $10/M output through August 31, 2026, then $3/$15 standard afterward. Fable 5 and Mythos 5 run at a 50% weekly usage limit through July 12, then meter at $10/$50 per million tokens.
Key Features
- Claude Opus 5: Claude Opus 5 launched July 24, 2026 as Anthropic's new flagship, approaching Claude Fable 5's frontier intelligence at roughly half the price and posting the strongest internal benchmark results yet on evaluations like Frontier-Bench and GDPval-AA.
- Claude Sonnet 5: Agentic model released June 30, 2026 with near-Opus 4.8 performance, now the default on Free and Pro plans. Sonnet 5 plans multi-step tasks, calls tools like browsers and terminals, and executes autonomously at a level that previously required larger models.
- Claude Science: Auditable AI workbench for scientific research with literature analysis, multi-step experiments, artifact generation, and manuscript development for peer review.
- MCP Support: Model Context Protocol support ships on every tier, letting Claude connect directly to external tools, databases, and file systems through a standardized protocol instead of custom integrations.
- Vision & Code Execution: Analyzes images and runs Python code in a sandbox, combining multimodal reasoning with practical computation.
- Enterprise Deployment: Available on AWS, Google Cloud, and Microsoft Azure with SSO, spend alerts, and API entitlements for team/enterprise plans.
- Claude Code's 1M-Token Context: Sonnet 5 is the default model in Claude Code, Anthropic's coding agent, with a 1-million-token context window for full-repository analysis in a single session.
- Claude for Government (beta): Beta compliance features and richer admin analytics showing usage and cost by group and user.
Pros
- The 1-million-token context window on Max plans is large enough to hold an entire codebase, a long legal contract, or hundreds of research papers in one session, a rare capability among frontier chat assistants.
- Claude Opus 4.8 leads SWE-bench Verified at 88.6% and GPQA Diamond at 93.6%, ahead of all publicly benchmarked alternatives as of May 2026.
- SOC 2 Type II, ISO 27001:2022, HIPAA (with BAA), and Zero Data Retention make Claude the compliance-ready choice for regulated industries including healthcare, legal, and financial services.
Cons
- No native image, audio, or video generation: Claude accepts image inputs but outputs only text and code, requiring a separate tool for any generative media task.
- Trustpilot shows a wave of April 2026 billing complaints over unauthorized gift-subscription charges and double-billing, indicating Anthropic's billing and support operations have not kept pace with growth.
- Free tier only includes base Haiku-class models; unlocking Sonnet 5 for daily use and occasional Opus access requires a paid plan, so the real cost of full capability is higher than the free headline suggests.
Frequently Asked Questions
How much does Claude cost in 2026?
Claude's Free plan costs nothing and defaults to Sonnet 5 with limited daily messages. Pro is $20 a month for higher limits and priority Opus access, while Max 5x ($100/month) and Max 20x ($200/month) add a 1-million-token context window. Team plans run $25 or $125 per seat per month, Enterprise is custom-priced, and the developer API bills Sonnet 5 at an introductory $2 per million input tokens and $10 per million output tokens through August 31, 2026, reverting to $3/$15 afterward.
Is Claude free to use?
Yes, the Free plan has no cost and includes a limited number of daily messages with Sonnet 5 as the default model, plus basic vision and file uploads. It does not include voice mode, priority Opus access, or the 1-million-token context window, which are reserved for Pro and Max. Message limits reset daily and can tighten during weekday peak hours.
What are the best alternatives to Claude?
ChatGPT is the closest mainstream alternative, with stronger native image and video generation through DALL-E and Sora integrations. Gemini offers a comparable large context window and tighter Google Workspace integration for teams already on Google Cloud. Perplexity is a better fit for citation-heavy web research rather than coding or long-document work.
How does Claude compare to ChatGPT in 2026?
Claude and ChatGPT both charge $20/month for their base paid plan, so the choice comes down to strengths rather than price. Claude's Sonnet 5 leads on long-document analysis and autonomous multi-step coding, while ChatGPT keeps the edge on generated visuals via DALL-E and Sora. Teams handling regulated data often pick Claude for its Zero Data Retention and HIPAA-ready compliance, which ChatGPT's consumer plans don't match.
How do you get started with Claude?
Sign up free at claude.ai or console.anthropic.com; no credit card is required for the Free plan. New users get Sonnet 5 by default in the chat interface, or can generate an API key from the developer console to integrate Claude into an application. Developers building coding workflows can install Claude Code from the same console and connect it to a terminal or IDE in a few minutes.
Top Alternatives
- ChatGPT: Pick Claude for coding depth and long-context analysis; pick ChatGPT for its Codex agent and broader multimodal generation.
