# Models

Strategies on Everstrike can utilize the following models:

<table><thead><tr><th width="235.16015625">Model</th><th width="136.51171875">Speed</th><th width="173.26171875">Cost Per Evaluation</th><th>Description</th></tr></thead><tbody><tr><td>GPT-4o-mini</td><td>1s</td><td>$0.000125</td><td>Oldest model.</td></tr><tr><td>GPT-4.1</td><td>1.5s</td><td>$0.0015</td><td>Fast, expensive and powerful model.</td></tr><tr><td>GPT-4.1-mini</td><td>1s</td><td>$0.00015</td><td>Default model.

Notes:&#x20;

* Strategies with an evaluation frequency of 15 seconds or less are restricted to the GPT-4.1-nano model.
* The listed model speed is an average. In reality, the speed depends not only on the model, but also on the user prompt and the data that the model has to consider. There is no guarantee that a model will finish its evaluation within the specified time.
* The cost per evaluation can be reduced by restricting the amount of data that a strategy has access to. This can result in cost savings up to 50%. See [Supported Data](/ai/supported-data.md) for a list of data points that you may include or exclude.

# Agent Instructions: Querying This Documentation

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://references.everstrike.io/ai/models.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
