Anthropic says new safeguards sharply reduce AI distillation attacksAnthropic said reasoning-token extraction is now 10 to 100 times lower than before after it restricted access patterns, blocked proxy networks and banned tens of thousands of accounts. The company identified campaigns associated with Chinese AI firms including Z.ai, while acknowledging the claims were based on its own monitoring.→OpenAI links a 16,000-request reasoning-extraction campaign to Moonshot-associated usersOpenAI said activity peaked at 16,000 requests from more than 4,000 users on July 24 and 25, with a broader related cluster exceeding 15,000 users. The operators copied encrypted reasoning between conversations and asked another model to decrypt it; OpenAI said no encryption or stored user data was compromised.→Experts dispute claims that Kimi K3’s capability came mainly from Fable distillationUS officials alleged that Moonshot used covert distillation of Anthropic’s model and restricted Nvidia hardware, but the reporting did not include technical evidence for the claim. Independent researchers argued that the timing and training requirements make simple distillation an insufficient explanation for Kimi K3’s performance.→
