BREAKING: Claude Sonnet 5.5 and Claude Haiku 5.5 by @AnthropicAI land on Design Arena's Pareto frontier for price vs. performance in Data Visualization, Game Dev and UI Components, and Haiku 5.5 makes the 3D Design frontier too. In these arenas, no other model is both cheaper and higher-rated.
Sonnet 5.5 takes #2 in Data Visualization and #3 in both Game Dev and UI Components.
Haiku 5.5 is the standout for value. At just $0.10/$0.50 per 1M input/output tokens, it costs a tenth as much as Haiku 4.5 and ranks far higher across single-shot HTML categories:
> #11 in 3D Design, up from #114 for Haiku 4.5
> #15 in Data Visualization, up from #121
> #20 in UI Components, up from #120
> #24 in Game Dev, up from #121
Congratulations to the Anthropic team on delivering this much quality at such a low cost.
