Anthropic removes Opus4.6 from Claude Code. Opus4.7 released, replacing its predecessor.
As we reported on April 22, Google engineers have been turning to Anthropic's Claude Code amid internal challenges. Now, a significant development has occurred with the silent removal of Opus4.6 from Claude Code. This move has raised questions, particularly since Opus4.6 was working fine after cache problems were resolved. The removal comes on the heels of the release of Opus4.7, suggesting a potential shift in Anthropic's strategy.
This development matters because Opus4.6 was a flagship model, representing a major leap in intelligence for complex workflows, professional-grade coding, and deep reasoning. Its removal may impact users who have grown accustomed to its capabilities, especially those who have been using it for tasks like catching blind spots early and persisting on difficult tasks.
What to watch next is how Anthropic will address the concerns of its users and whether the removal of Opus4.6 is a sign of a larger strategy to push users towards newer models like Opus4.7. Additionally, it will be interesting to see how this move affects the competitive landscape, particularly in relation to OpenAI's offerings, given the recent exchange between OpenAI CEO Sam Altman and Anthropic over marketing strategies.
