Claude Fable 5 is a Mythos-class model from Anthropic, built for autonomous knowledge work and coding. It supports text, image, and file inputs with text output, with reasoning support and a 1M-token context window. It is suited for long-running, complex, and asynchronous tasks that previously required frequent human check-ins.

Claude Opus 4.6 brings Anthropic's advanced reasoning capabilities to high-stakes workflows. With full adaptive thinking support and a 1-million-token context window, it excels at complex tasks across coding, cybersecurity, financial analysis, and large-scale enterprise agents.

Claude Opus 4.7 excels in autonomous multi-step engineering and long-horizon agentic workflows. It features an Effort Control layer for self-correction and advanced visual intelligence, making it an ideal choice for software engineering, legal, and financial analyses.

Claude Opus 4.8 is a workhorse flagship model designed for high-end reasoning and long-horizon agentic coding. It offers exceptional consistency and autonomy to sustain work on complex, long-running tasks.

Claude Opus 5 is Anthropic's flagship model designed for complex agentic coding and enterprise work, delivering intelligence close to Claude Fable 5 at half the price. It features a 1M token context window, adaptive thinking, and state-of-the-art performance on coding and knowledge work evaluations. It is optimized for bounded, complex tasks

Claude Sonnet 4.6 is Anthropic's balanced production model, offering near-Opus level intelligence at a much lower cost. It features a full upgrade across coding, computer use, long-context reasoning, agent planning, knowledge work, and design, along with an adaptive thinking capability.

Claude Sonnet 5 is the most agentic Sonnet model yet, released by Anthropic on June 30, 2026. It offers a 1M token context window and 128k max output tokens. It is designed for complex, multi-step agentic tasks like coding, tool use, and autonomous planning, achieving performance close to the more expensive Opus 4.8 model. It features adaptive thinking enabled by default and a new tokenizer that produces approximately 30% more tokens for the same text compared to Sonnet 4.6.
