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
