About
Claude Opus Latest is Anthropic’s model identifier that always redirects to the latest model in the Claude Opus family. The model accepts text, images, and files, and produces text outputs. It supports tools, vision, and reasoning, with a 1,000,000-token context window and a maximum output of 128,000 tokens. The listed model ID is ~anthropic/claude-opus-latest, and its official site is OpenRouter. It was released and created on 2026-04-21. Input pricing is 4 USD per 1M tokens, while output pricing is 20 USD per 1M tokens. Because the identifier redirects to the latest family member, behavior and capabilities may follow whichever Claude Opus model is current behind that alias. Builders can therefore use one endpoint while targeting the family’s latest model, provided their integration handles a moving model target and the stated text, image, and file inputs.
