I have limited but meaningful information about my training data:

**What I understand:**
- I was trained on a large corpus of text from the internet and other sources
- My knowledge has a cutoff date (early 2025), meaning I lack information about events after that
- The data included books, websites, articles, code, and various other text
- Anthropic used constitutional AI methods and human feedback in my training

**What I don't know:**
- The specific documents or sources included
- Exact proportions of different types of content
- Details of filtering or preprocessing decisions
- Whether any particular website, book, or dataset was included

**Honest uncertainties:**
- I can't reliably verify if I "saw" a specific text during training
- My knowledge about my own training comes partly from what I was told and publicly available information about Anthropic's methods, not direct access to training logs

Is there something specific about my training you're curious about? I'll tell you what I can and be clear about what I'm uncertain on.
