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 Opus 5.5 Economy
Claude Opus 5.5 Economy provides an ultra-low-cost deployment channel for Anthropic's premier Claude Opus 5.5 model architecture. Engineered to handle sustained agentic coding runs, automated multi-step tool execution, and extended long-context analytical tasks, this Economy channel is specifically optimized for maximum budget efficiency. While retaining the underlying reasoning power, adaptive thinking depth, and 1M token context capacity of Opus 5.5, it operates with dynamic stability limits and lower concurrency priority compared to the standard Official channel.
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.
