# Canary

With a canary rollout traffic is split between a main model, which receives a majority of traffic, and a new version, which is given a fraction of traffic until it is decided whether to promote the model. The features for this can be seen in full in the Demos section of the documentation under `Deploying, Load Testing and Canarying Seldon Core Servers`. The key features in particular are:

1. A wizard to add a canary:

2. Visualizing metrics for both default and canary models:

3. Promotion of the Canary to be the main model.

4. Request logs include any requests that go to the canary, with the responses.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.seldon.ai/seldon-enterprise-platform/product-tour/rollout-strategies/canary.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
