Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Dynamic Model Configuration

What changed: Models can now be configured remotely via Statsig Impact:

  • Claude Code can receive model updates without requiring new releases
  • Supports time-based feature gating for gradual rollouts
  • Enables A/B testing of different model configurations
  • External overrides respect user's first usage date to prevent unexpected changes
