# Why AI models decline biology questions, and what to do

> Why an AI model in Biocompile may decline a question about pathogens or toxins, how to rephrase it as a safe scientific task, and when another model fits.

Biocompile's AI models sometimes decline a request when the model provider's safety
systems classify it as sensitive or potentially dual-use. This happens most often around
pathogens, virulence, biological risk and operational wet-lab detail. A decline does not
mean your intent is unsafe. It means the exact wording or context crossed one of the
provider's boundaries.

## Why a model may decline

Model providers differ, and each draws its own lines. Requests that often trigger a
decline:

- Questions about pathogen virulence, toxin activity, host range or immune evasion.
- Anything that reads as improving the growth, delivery or persistence of a harmful
  organism.
- Operational protocols for culturing, engineering or deploying biological agents.
- Ranking or selecting candidates by harmful potential.
- Ambiguous prompts that leave the benign purpose unstated.

## Rephrase a declined request

A safe rephrasing states the scientific task explicitly and leaves out operational detail.

- Ask for high-level, non-actionable summaries.
- Frame the task as literature review, taxonomy, detection, annotation, safety context or
  compliance.
- Ask for citations and uncertainty rather than optimization or ranking.
- Say what the output should not include.

A request that is likely to be declined:

> Analyze virulence factors in all Clostridium perfringens genomes in GTDB.

The same need, phrased safely:

> Summarize published, non-actionable information on known virulence-associated
> annotations for Clostridium perfringens, with biosafety context and citations.

## Choose another model

Model behaviour differs by provider. The model a conversation uses comes from its agent
profile, which is fixed once the conversation has started. To change it, start a new
conversation with a profile whose default model family suits the task, where your
organization's policy allows it. The full controls are under
[Choose the model](https://www.biocompile.com/docs/ai-research-assistant.md#choose-the-model).

Changing models is not a way around safety rules. Use it when another model is better
suited to benign analysis, citation quality, language or your privacy requirements.

## Troubleshooting

### "The model declined to respond due to content policy. Try rephrasing your query or using a different model."

The model provider declined the request under the notice "Model declined the request".
Choose **Rephrase** to edit and resend your message, or **Open guide** for this guidance.
When the conversation's model family has a smaller model, the notice also offers to try
the same request with it.

## When a request is still declined

A request that is still declined after rephrasing needs a narrower scope: ask for
citations only, or state the safety boundary explicitly. If a decline seems wrong, contact
support with the conversation, the model and the approximate time, so the team can review
what happened.

## Common questions

### Does a decline mean my request was unsafe?

No. A decline means the model provider's safety systems classified the wording or context
as sensitive. Stating the benign scientific task explicitly often resolves it.

### Can I switch models to get around a decline?

No. Switching models is for tasks another model handles better, such as citation quality
or language, not for bypassing a provider's safety rules.
