Grok Models by xAI
About
The Grok family of large language models (LLMs) originates from xAI, Elon Musk's AI company. The initial model, Grok-1, marked a significant leap in AI capabilities, especially in reasoning and coding, as it surpassed numerous contemporaries in its computational class 2. Its architecture is notable for utilizing a Mixture-of-Experts (MoE) design with 314 billion parameters and 8 experts, 2 of which are active at any given time 5. Building on this foundation, xAI introduced Grok-2, which further advanced reasoning capabilities and is accessible along with its smaller version, Grok-2 mini, to users on the X platform and through an enterprise API 1. These models are designed for versatility, adept at answering queries and assisting with coding tasks, and they distinguish themselves by incorporating real-time information from the X platform 21. Despite their impressive performance, concerns have emerged over the potential to generate harmful or biased content, due to the training data sourced from X 7.

Frequently Asked Questions
- What is Grok used for?
- Grok is used for coding. The family description and listed model capabilities point to those workloads as the best fit.
- How does Grok compare to Grok 1?
- Grok by xAI is strongest where you need coding, while Grok 1 by xAI is the closest related family to check for reasoning. Grok has 3 listed variants, so compare the specs and pricing tables before choosing a production model.
- Which Grok model should I use?
- If price is the main constraint, use the pricing table first because Grok does not have complete provider pricing in the local data. For the most capable/latest local choice, evaluate Grok Imagine Video.
