About
Grok-1 was the model behind xAI's first Grok assistant, introduced in November 2023. The product was presented as a conversational assistant with access to information from X and a distinctive, informal tone. Initial access was limited. The chatbot's access to X was a product capability, separate from the knowledge stored in the model's weights.
In March 2024, xAI published the Grok-1 base-model weights under Apache 2.0. That release described a 314-billion-parameter mixture-of-experts model and did not include the chat fine-tuning or live retrieval system used by the assistant. For anyone comparing downloadable Grok-1 with the original chatbot, this distinction matters: the open base checkpoint was a foundation for further work, rather than the complete X-connected service.
