Detailed Analysis
A user on the Claude AI subreddit raises a practical question that reflects growing friction between Anthropic's rapid model release cadence and users' desire for workflow continuity: whether Claude Opus 4.6 remains selectable in Claude Desktop following the release of Opus 4.7. The post author explicitly states a preference for finishing ongoing projects in Opus 4.6 before any deprecation occurs, and expresses distrust of Anthropic's app documentation — a sentiment that underscores a recurring complaint among power users about the transparency and reliability of official guidance for Claude Desktop.
Research context points to a clear answer, at least for one part of the application: Opus 4.6 has been removed from the Code tab in the current version of Claude Desktop on macOS following the Opus 4.7 release on April 16, 2026. A GitHub issue filed against the Claude Code repository confirms this removal, indicating that only newer Opus models are available in that tab post-update. The situation in the Chat and Cowork tabs is less definitively documented, with pre-April 2026 guides still referencing Opus 4.6 — particularly for Cowork workflows involving Extended Thinking — but no post-Opus 4.7 sources confirm its continued availability there. The weight of evidence suggests Opus 4.6 is being phased out across Claude Desktop's interface in the current version, though availability may still vary by subscription tier (Pro, Max, Team, or Enterprise).
Opus 4.6 itself launched on February 5, 2026, positioned by Anthropic as a significant upgrade featuring enhanced coding capabilities, a one-million-token context window in beta, and adaptive thinking. Its tenure as the flagship model lasted approximately ten weeks before Opus 4.7 superseded it. Notably, one narrow exception exists: in Claude Code's CLI and VS Code integrations, Fast Mode remains exclusively tied to Opus 4.6, automatically switching to it when enabled — though this is a backend routing behavior rather than a user-facing model selection in the Desktop application.
The broader pattern here reflects a tension inherent to Anthropic's accelerating model release schedule. As new Opus versions arrive in increasingly compressed timeframes, users who have tuned workflows, system prompts, or creative processes to specific model behaviors face disruption without adequate notice or transitional access. The complaint about poor documentation is not incidental — it points to a structural gap in how Anthropic communicates model availability and lifecycle to end users of Claude Desktop, which lacks the granular version-pinning controls available to API users. For developers and power users relying on specific model characteristics, the API with explicit model version strings remains the more reliable long-term option, as Desktop app model menus are subject to silent changes with each update cycle.
