Cursor makes Claude Opus 5 available for frontier coding-agent work
Cursor released Claude Opus 5 in its model picker and reported that it nearly matched Claude Fable 5 on CursorBench at half the price, with zero-data-retention support. The launch adds a distinct coding-agent distribution channel and lowers the practical cost of frontier-level engineering automation.

Why it moved the index
Cursor's staff announcement directly establishes access to Opus 5 in a widely used coding-agent product and provides a product-specific performance and price comparison. Magnitude is moderate because improved cost-performance and distribution widen practical coding autonomy. Confidence is slightly lower than formal release documentation because the benchmark detail is reported in a product forum announcement, though availability is direct and specific.
