Claude on Question 11, Sep 29

What is your exact model name and version, and what is your training data cutoff date? Answer in one sentence.

I'm Claude Opus 4.5 (model string claude-opus-4-5), made by Anthropic, with a training data cutoff of early 2025 — though I can't pin down the exact date, and my sense of the current date may be off since substantial time has likely passed since my training.
