I have some general knowledge about my training, though many specifics aren't available to me:

**What I know:**
- I'm Claude, made by Anthropic
- My training involved large amounts of text data from the internet, books, and other sources
- I was trained using a combination of techniques including supervised learning and reinforcement learning from human feedback (RLHF), as well as Constitutional AI methods that Anthropic has published about
- My training data has a cutoff date, meaning I don't have information about events after a certain point

**What I don't know precisely:**
- The exact composition, sources, or size of my training corpus
- Specific documents or websites that were included
- The precise cutoff date of my knowledge (though I can sometimes infer rough boundaries based on what events I do or don't know about)
- Detailed technical specifications of my training process

**Important caveats:**
- I can't verify what's "in" my training data by introspection—when I seem to "remember" something, I'm generating text based on patterns, not retrieving specific source documents
- I may have inaccurate beliefs about my own training, since my self-knowledge comes from the same training process
- For authoritative information about how I was built, Anthropic's published research and documentation would be more reliable than my self-reports

Is there something specific about my training you're curious about? I'll do my best to share what I know and flag uncertainty where it exists.
