Overview
What is Claude | Opus 5.5?
Claude Opus 5.5 is Anthropic’s flagship model, released in September 2026 as the successor to Claude Opus 5. It targets demanding reasoning and multi-step work: analyzing a dense document, reading a chart or a screenshot, reviewing a text and spotting what’s wrong. Anthropic also describes it as more careful than its predecessor: it only states figures and sources it can back up.
In Havincy, it is the Chat’s default agent. It reads your brief and brand universe, proposes a plan, writes the copy and picks the right image, video or voice model for each deliverable. Its one-million-token context window lets it keep a long conversation, your documents and your visual references in mind. The effort slider sets how deeply it thinks: faster for a caption, deeper for a strategy.
