Claude
Designed for real-world enterprise agentic workflows, the Claude 5 lineup introduces a clear tiered intelligence architecture: Claude Fable 5 (the state-of-the-art flagship for complex long-horizon research), Claude Opus 5 (built for agentic software development and complex engineering tasks), Claude Sonnet 5 (the ultimate combination of speed and high intelligence), and Claude Haiku 4.5 (ultra-fast, cost-effective execution).
All Models
Claude Fable 5.1 Economy
Claude Fable 5.1 is Anthropic's upgraded flagship frontier model engineered for high-complexity software development, long-horizon agentic workflows, and multi-step knowledge work. Built on Mythos-tier reasoning, Fable 5.1 significantly enhances autonomous self-verification and root-cause troubleshooting while reducing safety false-positive interventions by up to 60%. Powered by an optimized prompt-caching architecture featuring a 75% reduction in cache-read pricing, it cuts total operating costs by 25% to 45% for highly agentic tasks.
Claude Opus 5 Economy
Claude Opus 5 is Anthropic's ultra-flagship frontier model engineered for extreme cognitive density, deep logical reasoning, and expert-level scientific synthesis. Powered by native adaptive thinking and a 1-million-token context window, it resolves complex multi-step mathematical, architectural, and coding challenges with unprecedented accuracy and near-zero hallucination rates. Coupled with rigorous enterprise safety alignment, Claude Opus 5 excels at high-stakes operations, including legal compliance, quantitative financial modeling, advanced biosecurity research, and mission-critical software architecture auditing.
Claude Opus 4.8 Economy
Claude Opus 4.8 is Anthropic’s most powerful officially released Opus model, designed for complex reasoning, long-horizon agentic coding, and highly autonomous professional workflows. It supports text, image, and file inputs and produces text output. It features a 1-million-token context window, up to 128,000 output tokens, and built-in capabilities for adaptive thinking, tool use, and structured outputs. The model excels at advanced coding, browser and computer-use agents, enterprise knowledge work, financial and legal analysis, and multi-step tasks requiring sustained judgment and high reliability.
Claude Fable 5 Economy
Claude Fable 5 is Anthropic’s officially released Mythos-tier model, designed for autonomous knowledge work, advanced reasoning, and long-horizon coding. It supports text, image, and file inputs and produces text output. It features a 1-million-token context window, up to 128,000 output tokens, and built-in always-on adaptive thinking, tool use, and structured outputs. The model shares the same underlying model family as Claude Mythos 5 but was released publicly with stronger safety safeguards. It is suitable for complex software engineering, multi-step agentic workflows, enterprise research, document analysis, and professional tasks requiring sustained reasoning and high reliability.
Claude Sonnet 5 Economy
Sonnet 5 is Anthropic’s most capable Sonnet-class model, delivering frontier-level performance across coding, agentic workflows, and professional tasks. It features adaptive thinking with selectable reasoning levels—**low**, **medium**, **high**, **max**, and **x-high**—along with a 1-million-token context window and support for text, image, and file inputs. Built with an updated tokenizer, Sonnet 5 also incorporates real-time cybersecurity safeguards designed to block high-risk dual-use activities.
Claude Haiku 4.5 Economy
Claude Haiku 4.5 is Anthropic’s fastest and most efficient model, delivering near-frontier intelligence with significantly lower cost and latency than larger Claude models. With performance comparable to Claude Sonnet 4 across reasoning, coding, and computer-use tasks, it brings advanced capabilities to real-time, high-volume applications. As the first Haiku model to support extended thinking, Haiku 4.5 offers adjustable reasoning depth, summarized or interleaved thinking, and tool-assisted workflows spanning coding, Bash, web search, and computer use. Scoring over 73% on SWE-bench Verified, it ranks among the world’s leading coding models while remaining highly responsive for sub-agent orchestration, parallel execution, and large-scale deployment.
Claude Opus 4.6 Economy
Claude Opus 4.6 is Anthropic’s most powerful officially released Opus model, designed for complex reasoning, long-horizon agentic coding, and highly autonomous professional workflows. It supports text, image, and file inputs and produces text output. It features a 1-million-token context window, up to 128,000 output tokens, and built-in capabilities for adaptive thinking, tool use, and structured outputs. The model excels at advanced coding, browser and computer-use agents, enterprise knowledge work, financial and legal analysis, and multi-step tasks requiring sustained judgment and high reliability.
Claude Opus 4.7 Economy
Claude Opus 4.7 is Anthropic’s most powerful officially released Opus model, designed for complex reasoning, long-horizon agentic coding, and highly autonomous professional workflows. It supports text, image, and file inputs and produces text output. It features a 1-million-token context window, up to 128,000 output tokens, and built-in capabilities for adaptive thinking, tool use, and structured outputs. The model excels at advanced coding, browser and computer-use agents, enterprise knowledge work, financial and legal analysis, and multi-step tasks requiring sustained judgment and high reliability.
