Replit Power Mode Now Runs on Claude Opus 4.7

Replit Power Mode Upgraded to Claude Opus 4.7

Replit has upgraded its Power mode to run on Claude Opus 4.7, Anthropic's newest flagship model released on April 16, 2026. Users who select Power from the Agent modes dropdown now automatically benefit from the improved model without any configuration changes required.

What Changed

Previously, Power mode operated on Claude Opus 4.6. The switch to Opus 4.7 brings meaningful improvements across the tasks that Replit users depend on most. Anthropic's new model achieves stronger performance on long-running software tasks, complex debugging, and higher-resolution vision — capabilities that map directly to Replit's agentic workflows.

Replit reported that Opus 4.7 achieves the same quality as its predecessor at lower cost, meaning the upgrade translates to both better results and more efficient credit usage for Power mode users. Replit President Michele Catasta noted the model is "more efficient and precise at tasks like analyzing logs and traces, finding bugs, and proposing fixes," adding that it "really feels like a better coworker."

Addressing Real Developer Pain Points

One of the more notable improvements Replit's team highlighted is how Opus 4.7 handles failure modes that were still frustrating with Opus 4.6. In particular, the new model is less likely to give up on hard debugging problems, less likely to loop on tool errors, and less likely to produce code that technically runs but quietly skips the ambiguous part of the spec. For builders using Replit Agent on production-grade projects, these improvements have a direct impact on how much intervention is required during a build session.

Broader Context

The Opus 4.7 launch was notable across the developer tools ecosystem. Anthropic's launch post included early-access quotes from Linear, Cursor, Vercel, Replit, Notion, Warp, Devin, Bolt, and others — all reporting positive results from integrating the new model. Anthropic also introduced a new xhigh effort level with Opus 4.7, positioned between high and max, for situations requiring sustained effort without full resource saturation.

For Replit Power mode users, no action is required — the upgrade is automatic and applies to all new Agent sessions started in Power mode from April 17, 2026 onward.
