Anthropic has released the second Anthropic Economic Index report, analyzing usage data following the launch of Claude 3.7 Sonnet. This analysis was based on 1 million Claude.ai conversations collected over 11 days.

Key changes include an increase in the usage share of coding, education, science, and healthcare fields. In particular, Claude 3.7 Sonnet's new 'extended thinking' mode was found to be mainly used by technical occupations such as computer science researchers, software developers, and game designers.

The analysis also included results based on work patterns:

  • Copywriters and editors: Have the highest share of 'task iteration', where humans and the model collaborate to write.
  • Translators and interpreters: Have a very high share of 'directive' behavior, where the model completes tasks with minimal intervention.
