# Models

Strategies on Everstrike can utilize the following models:

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](https://references.everstrike.io/ai/supported-data) for a list of data points that you may include or exclude.
