Claude models include safeguards that can flag a message and stop the response. Some are intentionally broad and can flag legitimate coding, cybersecurity, and biology work. See Our Approach to User Safety for more about these safeguards.

​
When safeguards flag a message

When a model’s safeguards flag a message, Claude Science pauses the session and shows a Chat paused card above the composer, unless it switches models automatically. If another model can continue, select Retry with <model> to retry on the model the card names. That model has its own safeguards. The session stays on it until you choose a different model in the composer.

​
Switch models automatically

When safeguards flag a message for content related to life sciences research, Claude Science can retry it right away on another model instead of stopping at the Chat paused card. It does this only when a model is available for automatic switching, and at most once per message. A notice names the model it switched to, and the session stays on that model until you choose a different one in the composer. Automatic switching is on by default. To turn it off, go to Settings > General > Model and turn off the Switch models when a message is flagged toggle. The Chat paused card shows the same toggle when it offers Retry with <model>. Turning the toggle on from the card can also retry the paused message right away.

Life Sciences Verification Program (beta)

Under Anthropic’s Life Sciences Verification Program (beta), verified organizations on Team and Enterprise plans can use Claude models with fewer life sciences restrictions. Protections against the most serious misuse stay in place, and safeguards can still flag a message. What is the Life Sciences Verification Program? has the details, including which models it applies to and how an organization applies.

​
Choose a use case

If you have access through the Life Sciences Verification Program (beta), your organization specified one or more approved research use cases. Claude Science sends a session’s use case with the requests it makes for that session, so Claude’s safeguards can apply the access approved for that work. Anthropic also monitors program usage against the scope your organization shared when it applied. See What is the Life Sciences Verification Program? for data retention and safety review. With one use case, Claude Science applies it to every session. With more than one use case, you choose one for each session:
  • Claude Science asks you to choose the one that matches your work when you first send a message in a session, unless you’ve set a default. Everyday tasks like writing or coding are allowed with any use case.
  • To switch during a session, open the model picker in the composer and select Use case.
  • To set a default on this computer, select Set as default when Claude Science offers it, or choose one from the Default use case menu under Settings > General > Model.
The use case controls need version 0.1.49 or later of the Claude Science app. If you’re up to date and don’t see a use case, ask your organization’s admin.
