Grok-1
Grok-1 is a mixture-of-experts (MoE) large language model (LLM) with 314B parameters which includes the open release of the base model weights and network architecture.
Grok-1 is trained by xAI and consists of MoE model that activates 25% of the weights for a given token at inference time. The pretraining cutoff date for Grok-1 is October 2023.
As stated in the official announcement (opens in a new tab), Grok-1 is the raw base model checkpoint from the pre-training phase which means that it has not been fine-tuned for any specific application like conversational agents.
The model has been released (opens in a new tab) under the Apache 2.0 license.
Results and Capabilities
According to the initial announcement (opens in a new tab), Grok-1 demonstrated strong capabilities across reasoning and coding tasks. The last publicly available results show that Grok-1 achieves 63.2% on the HumanEval coding task and 73% on MMLU. It generally outperforms ChatGPT-3.5 and Inflection-1 but still falls behind improved models like GPT-4.
Grok-1 was also reported to score a C (59%) compared to a B (68%) from GPT-4 on the Hungarian national high school finals in mathematics.

Due to the size of Grok-1 (314B parameters), xAI recommends a multi-GPU machine to test the model.
