Faster, safer, smarter, cheaper: Anthropic makes the case for Claude Sonnet 5.5

TL;DR Anthropic is introducing Claude Sonnet 5.5 as an optimized alternative to Opus 5.5. While Opus 5.5 edges still edges out Sonnet in many tasks, Sonnet’s speed and low cost of operation make it still worth considering. Sonnet 5.5 represents an even more significant improvement over Sonnet 5, while retaining the same low cost.
