Anthropic models
Anthropic builds the Claude family, known for careful reasoning, strong writing and reliable tool use. Zeplik leads with Claude Opus 5.5, Anthropic's flagship for demanding reasoning, coding and long-horizon agentic work, which succeeds Claude Opus 5 at a lower price on both input and output. Alongside it Zeplik carries Claude Fable 5.1 and the rest of the current generation — Claude Opus 5, Claude Sonnet 5 and Claude Fable 5 — with the Opus 4.x line and earlier Sonnet and Haiku releases behind them.
