Claude Opus 4.8

« A reasoning model that is twice as fast and half the cost, works longer on difficult tasks, checks its own work more thoroughly, and is highly resistant to attempts to circumvent it. It integrates easily with Cursor or via API »

« A powerful LLM model designed for coding, research, and long-running agentic tasks, featuring 500,000 tokens of context, tool calls, and fine-tuned reasoning effort. Available directly in Cursor and Grok Build »

« An AI model built for code and autonomous agents. It features a context window of one million tokens and enables detailed analysis of documents, charts, and screenshots. It is 40% less expensive than its predecessor (Opus 5) »

« Discover a next-generation AI model designed for advanced use while remaining highly secure. You’ll enjoy top-tier performance for coding, analysis, and research, while safeguards block sensitive applications such as cybersecurity and biology »

« Choose between two models optimized for professional work, coding, and using tools. They improve speed and significantly reduce costs compared to the previous generation »

« A model that is 30% faster and up to 30% less expensive than the Sonnet 5 version, designed for debugging, drafting polished documents, and creating presentations. It also allows you to work on texts, interfaces, and images »

« Moonshot's LLM model, which rivals the best proprietary models on numerous benchmarks. Designed for long-form coding, advanced reasoning, and knowledge work tasks, it is also the first open-source model to surpass the 2.8 trillion-parameter mark »

« A premium model designed for everyday use, offering improved capabilities in coding, reasoning, and agent-based tasks, while remaining more affordable than the next tier up. Available on the Pro and Max plans at Anthropic »
