xAI

tip

If you installed lfx directly with uv pip install lfx, install this provider from the long-tail metapackage:

uv pip install "lfx-bundles[<bundle>]"

Replace <bundle> with this page's provider name, for example qdrant. To install every long-tail provider at once, run uv pip install "lfx[bundles]". See the Bundle list for the exact extra name.

If you installed Langflow with uv pip install langflow, these bundle components are already included.

Bundles contain custom components that support specific third-party integrations with Langflow.

This page describes the components that are available in the xAI bundle.

For more information about xAI features and functionality used by xAI components, see the xAI documentation.

xAI text generation

The xAI component generates text using xAI models like Grok.

It can output either a Model Response (Message) or a Language Model (LanguageModel).

Use the Language Model output when you want to use an xAI model as the LLM for another LLM-driven component, such as an Agent or Smart Transform component.

For more information, see Language model components.

xAI text generation parameters

Some parameters are hidden by default in the visual editor. You can modify all component parameters through the component inspection panel that appears when you select a component.
