Editing Grok (section)

== History ==

xAI was founded by Elon Musk in March 2023 with the mission "to understand the true nature of the universe." Grok was announced as xAI's flagship product shortly thereafter.

* '''November 2023''': Grok (powered by Grok-1) launched in early access for X Premium+ subscribers. The initial model was a 314-billion-parameter Mixture-of-Experts (MoE) architecture, with Grok-1 weights later released as open-source under Apache-2.0.<grok-card data-id="a3d6e8" data-type="citation_card" data-plain-type="render_inline_citation" ></grok-card>

* '''March 2024''': Grok-1.5 introduced improved reasoning, longer context (up to 128,000 tokens), and vision capabilities (Grok-1.5V).

* '''August 2024''': Grok-2 brought significant gains in reasoning, coding, math, and multimodal features, including image generation (via integration with models like FLUX.1). A lighter Grok-2 Mini variant was also released.

* '''February 2025''': Grok-3 marked a major leap, trained with approximately 10× more compute on xAI's Colossus supercomputer cluster (utilizing hundreds of thousands of Nvidia GPUs). It emphasized advanced reasoning agents, tool use, and performance surpassing many contemporaries in benchmarks for math, science, and coding.<grok-card data-id="e8491d" data-type="citation_card" data-plain-type="render_inline_citation" ></grok-card>

* '''2025 onward''': Subsequent updates included Grok 4 (described as one of the world's most capable models with native tool use, real-time search, and low hallucination rates) and enhancements like Grok Imagine for high-quality image and video generation (including 10-second 720p videos with audio).<grok-card data-id="250235" data-type="citation_card" data-plain-type="render_inline_citation" ></grok-card>

By 2026, Grok became widely accessible via grok.com, the X platform (web, iOS, Android), and an API for developers. xAI has also explored integrations and acquisitions, including ties to SpaceX.
