Census AI Columns now supports Anthropic's leading AI models, including Claude 3.5 Sonnet and Haiku, alongside GPT-4o and GPT-4o Mini. The addition brings significant performance improvements, particularly in complex reasoning tasks, but also presents a challenge in deciding which model to use due to varying performance numbers across different benchmark tests. While none of the models excel at complex reasoning, Claude 3.5 Sonnet stands out for its high accuracy in coding and graduate-level reasoning tasks, while GPT-4o offers well-rounded performance and consistency across various tasks. GPT-4o Mini is a budget-friendly option for high-volume data enrichment tasks. To get started, customers can begin with lower-cost models, identify critical use cases, A/B test different models, and monitor both performance and costs to optimize usage.
