Agentic Chat (Claude Opus 4.7) is GitLab Duo's integration of Anthropic's latest Opus-generation model, exposed inside the Duo Agent Platform for AI-assisted development work. GitLab announced the model's availability on its blog, positioning it as Anthropic's newest offering aimed at stronger agent behavior, and the Duo provider catalog lists it under the claude-opus family as a provider-specific routing entry. That positioning places it alongside sibling Duo deployments of Claude Opus 4.5, 4.6, and 4.8, signaling an ongoing pattern of bringing successive Opus revisions into GitLab's coding assistant surface for repository-aware tasks.

Practically, the model is configured for long-running, multi-step work: the Duo catalog advertises reasoning and tool-calling support, and the catalog row carries a one-the cataloged API limit that suits agents operating across large codebases. Within the Duo Agent Platform it fits use cases such as autonomous code review, refactoring proposals, security analysis follow-ups, and tool-driven investigation pipelines where the model can call external functions rather than only emit free-form text. Because the Anthropic base-model card and post-training details are not in the supplied evidence, the overview stays grounded in what GitLab and the catalog publish: it is a tool-using Opus variant delivered through Duo for agentic developer workflows.
