7474On the Claude API and Claude Models on Google Cloud (Google managed), with the `thinking-binding-controls-2026-08-01` [beta header](https://platform.claude.com/docs/en/api/beta-headers), the response lists each dropped block in `input_transformations` as a `thinking_dropped` entry with `reason: "organization_binding_mismatch"`. Without the header, the drop is silent.

7575

76The API can also leave out a thinking block that another account produced, if that account is no longer in good standing. This applies to requests to Claude Fable and Claude Mythos models, Claude Opus 5, Claude Opus 5.5, Claude Sonnet 5.5, and Claude Haiku 5.5. The request still succeeds, and the model answers without that block's reasoning.

7678## Keeping the prefix unchanged

7880On Claude Fable 5.1, Claude Opus 5.5, Claude Sonnet 5.5, and Claude Haiku 5.5, a thinking block stays valid only while everything you sent before it is unchanged on later requests. The checked prefix has three parts:

2727| Feature | What people see |

2828| ----------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

29| Chat search | Off. Members can't search past chats, because chat titles and content are encrypted with your key. The **Search and reference chats** toggle stays off, so Claude can't either. |

30| [Project knowledge search](https://support.claude.com/en/articles/11473015-retrieval-augmented-generation-rag-for-projects) (RAG) | Off. Project knowledge loads into each conversation's context instead of being indexed and searched. A project can use substantially less knowledge, and the rest is left out. |

3129| Claude Code on the web | Off. New sessions can't be started, even if an admin turns the product on. |

3230| Claude in Slack | Off. Claude declines requests, even if an admin turns the product on. |

3331| Claude Code Desktop | Off until an admin turns it on. Available for local sessions once turned on under [claude.ai > Organization settings > Claude Code](https://claude.ai/admin-settings/claude-code). |

3836| Analytics: skills and connectors | Changed. Admin analytics for skills and connectors, in the claude.ai analytics dashboard and through the [Claude Enterprise Analytics API](https://platform.claude.com/docs/en/manage-claude/analytics-api), don't include usage in chat, and hide the names of custom skills, plugins, and connectors. |

39| Organization data exports and audit log exports | Off. Both are under [claude.ai > Organization settings > Data and privacy](https://claude.ai/admin-settings/data-privacy-controls). |

4037| Response ratings (thumbs up and thumbs down) | Off. Members can't rate Claude's responses. |

4138| [Skill and plugin security scanning](https://platform.claude.com/docs/en/agents-and-tools/agent-skills/enterprise#skill-content-scanning) | Off. The setting can't be turned on, and skills and plugins are installed without a scan. |
