xAI

xAI is an American artificial intelligence company and wholly owned subsidiary of SpaceX. The company develops AI systems under the Grok brand, spanning language models, image generation, and video synthesis. xAI has quickly established itself as a multimodal AI lab with ambitions across both conversational intelligence and generative media.

On Venice, xAI offers nine models covering text, image, video, and inpainting. The text lineup includes Grok 4.1 Fast, Grok 4.20, and Grok 4.20 Multi-Agent — the latter designed for agentic, multi-step workflows. On the visual side, Grok Imagine and Grok Imagine Pro handle image generation, while dedicated video models support text-to-video, image-to-video, and reference-to-video pipelines via Grok Imagine R2V. A Grok Imagine inpainting model rounds out the catalog.

xAI stands out for the breadth of its generative stack — few providers ship text, image, video, and editing models under a single brand. The Grok 4.20 Multi-Agent model signals a push toward agentic AI, while the Grok Imagine family positions xAI as a serious competitor in visual generation alongside its language model efforts.
