Anthropic Releases System Prompts for Claude AI

Simon Willison1 min brief

In brief

  • Anthropic has made a significant move by publishing the system prompts used in their Claude AI applications, including Claude.ai and their mobile apps.
    • This is a big deal because it allows users to see exactly how the AI behaves and evolves over time.
  • For instance, they’ve shared historical changes like the original prompt from October 15th, 2023, and an updated one from January 18th, 2024.
  • The platform now organizes prompts by model version, such as Haiku 4.5 or Fable 5.1.
    • This makes it easy to compare different versions (or “diff” them) to see how the AI’s responses have been tweaked.
  • For example, they’ve added guidelines like avoiding song lyrics and copyrighted characters, improving how the AI handles conversations, and setting a reliable cutoff date of June 2024 for accurate information.
  • Looking ahead, this transparency could set a new standard in AI development.
  • Users can now track changes themselves, making AI systems more accountable and easier to understand.
    • It’s a step toward greater openness in the field, which is something many have been calling for.
