A user shared early hands-on impressions of Claude Sonnet 5.5: it feels faster, smarter and more efficient than Sonnet 5.0, sits quite close to Opus 5.5 in capability, and is roughly 30% more affordable.
Note this is anecdotal feedback rather than official benchmarks, but it's an early signal on the new model's price-performance.
