Beating AI Express: Anthropic has added another layer of restrictions to the thinking blocks of its Sonnet 5.5 model. The model’s generated thinking blocks are now tied to the account or organization that created them. When users switch accounts mid-session in scenarios like Claude Code, chat history remains accessible, but thinking blocks from the original account are discarded, requiring Claude to re-infer based on the existing conversation. Anthropic has also added checks for issues such as `organization_binding_mismatch` and `end_user_binding_mismatch` to its API. Previously, Anthropic introduced "context locking" for thinking blocks starting with Fable 5.1: original thinking blocks may become invalid if system prompts, tools, or prior messages are modified. The latest account binding measure is primarily to prevent attackers from switching accounts in batches to repeatedly exploit Claude’s high-quality generated reasoning for model distillation. Sonnet 5.5 is also the first Sonnet model equipped with a "reasoning extraction" prevention classifier. Anthropic notes that Sonnet 5.5’s capabilities are significantly higher than its predecessor, which led to the addition of these anti-distillation measures. The classifier targets large-scale scraping of Claude’s reasoning for training other models, with regular developers seeing almost no impact.
