According to Miles Deutscher, a recent study comparing Opus 4.6, the latest Claude model, to its predecessor Opus 4.5 across 165 tasks revealed no performance improvements. However, Opus 4.6 achieved significant advancements by reducing costs and wall time by 50%. While these are notable operational efficiencies, Deutscher advises caution when interpreting AI benchmarks and suggests testing models for specific use cases to evaluate their effectiveness.
