Claude Opus 4.7 vs Copilot: Which Should You Use?
A plain comparison of a model and an assistant for business buyers.
Anthropic released Claude Opus 4.7 on April 16, 2026, as a large language model for complex, multi-step work like coding and analysis.
The key difference is what you are comparing. Opus 4.7 is a model you access through the Claude API and Claude products. Copilot is Microsoft's assistant brand built into apps like Microsoft 365 and developer tools, and it can run different underlying models over time.
Business buyers care because the right pick depends on whether you want a model to build on or an assistant already inside your apps.
