> 3.4 million is the number of sessions Anthropic detected. The actual number of Claude sessions trained on is likely >100 million. That's an increase of only a single order of magnitude, increasing my estimate of exfiltrated tokens from 0.05 to 0.15 trillion - a far cry from the 15 trillion required. > They are used for post-training Possibly - it may be too much data for post-training, unless further curation was d…
You're conflating pre-training data volume with post-training data volume. Nobody is suggesting Moonshot used 15 trillion tokens of Claude data to pre-train a base model from scratch. That would be impossible and nonsensical. This is entirely about distillation, which happens during post-training (alignment and SFT). Here, datasets are measured in millions or billions of tokens, not trillions. 50 billion Claude token…
But from evidence it was data generated by Opus 4.5. Is Opus 4.5 larger, stronger model and Kimi K3 a weaker, student model? I don't think so.
Also, I searched on HuggingFace "fable data", first link was a "distillation dataset", including samples from Fable, there are 2 milion code samples of Fable output. So this fully legal and sits in the open, somehow is not a distillation attack? Who knows, maybe Moonshot used this for training.
