# Models and data

Vatio runs the model for you: there is no model to host and no model key in
`vatio.yml`. Every request to a model goes through
[OpenRouter](https://openrouter.ai), and only to endpoints with zero data
retention.

## Which models

Every agent uses the same models. Vatio picks them and may change them, and
this page always lists the current ones.

| Job | Model |
|---|---|
| Replying to visitors | DeepSeek V4.1 Flash (`deepseek/deepseek-v4.1-flash`) |
| [Memory](https://vatio.ai/docs/tools#memory) summaries and the question behind [`chat.rate`](https://vatio.ai/docs/sdk/reference) | The same model as the replies |
| Deciding when to ask for that rating | Jev, by Typesafe (`typesafe/jev-1.13`) |
| Transcribing voice notes | Voxtral Small, by Mistral (`mistralai/voxtral-small-24b-2507`) |
| Watching videos and reading PDFs | Gemini 3.8 Flash (`google/gemini-3.8-flash`) |
| Searching [knowledge](https://vatio.ai/docs/knowledge) | OpenAI `text-embedding-3-small` |
| Judging [evals](https://vatio.ai/docs/improve) | Gemini 3.8 Flash: a different family than the replies, so it never grades its own kind of answer |

DeepSeek's models are open-weight. OpenRouter serves them from independent
inference providers, not from DeepSeek's own API.

How long conversations stay in Vatio, and how to delete them, is in
[Retention and deletion](https://vatio.ai/docs/data).

## Zero data retention

Every request, replies and embeddings alike, asks OpenRouter for
[zero data retention](https://openrouter.ai/docs/guides/features/zdr)
endpoints only. The provider that runs the model keeps neither the prompt nor
the answer, and trains on neither. When no such endpoint is available the
request fails rather than going to one that keeps data: Vatio retries it, and
if it still fails the visitor gets the same message as for any reply that
could not be generated.

Vatio keeps the conversation itself, to run the inbox, memory and evals. The
[privacy policy](https://vatio.ai/legal/privacy-policy) lists every
sub-processor and where it runs.

## Using a different model

Choosing the model for an agent is not available yet. If yours needs a
specific one, such as a larger model for harder conversations or one your
company already approved, write to [support@vatio.ai](mailto:support@vatio.ai)
with the model and what it is for.
