Sonnet 5.5 is a great model, fantastic tool use, fast. It's also highlights the tradeoffs different models make in this case, humor We saw a significant regression on the @goodstartlabs LOL Alignment Bench 5.5 gets the joke less than Sonnet 4.5 did a year ago Makes sense as a small model focused mainly on tools, but these tradeoffs have real impacts on people using them We're going to need so many more: • creative • interpretable • diverse environments that make intelligence legible

Sonnet 5.5 improves on Sonnet 5 across benchmarks, in some cases dramatically. It’s a faster, lower-cost complement to Claude Opus 5.5, strongest at well-scoped everyday tasks, fixing bugs, and creating polished documents, slides, and spreadsheets. https://t.co/w8zB9WXxK7
