Claude Fable 5Anthropic's most capable widely released model, for the most demanding reasoning and long-horizon agentic work. Thinking is always on with a 1M token context window (also the maximum) and 128K max output. Priced above the Opus tier for the highest capability ceiling in the Claude lineup.
Claude Opus 5Anthropic's successor to Opus 4.8 for complex agentic coding and enterprise work. Strongest on deep reasoning, agentic and long-horizon work, and test-time compute scaling, at half the cost of Claude Fable 5. Thinking is on by default with a 1M token context window and 128K max output.
Claude Sonnet 5Best combination of speed and intelligence in the Sonnet tier, delivering near-Opus quality on coding and agentic work. Successor to Sonnet 4.6 with adaptive thinking on by default, a 1M token context window, and 128K max output.
