the rumor in chinese web is the following.

Z.ai found a way to crack/overcome the cryptography that safeguarded Claude/Fable's thinking tokens in Claude Code, so Z.ai had the ability to peak into decrypted thinking tokens that Fable produced in Claude Code. Z.ai also shared their findings with other big LLM companies like Moonshot AI, which had 20,000+ accounts speed running through Fable to get their hands on as many high quality thinking tokens as possible for distillation.
