Besides llama based models, LocalAI is compatible also with other architectures. The table below lists all the backends, compatible models families and the associated repository.
{{% notice note %}}
LocalAI will attempt to automatically load models which are not explicitly configured for a specific backend. You can specify the backend to use by configuring a model with a YAML file. See [the advanced section]({{%relref "advanced" %}}) for more details.
All backends listed here can be installed on demand from the [Backend Gallery]({{%relref "features/backends" %}}). The exact set of acceleration variants published for each backend is defined in backend/index.yaml.
