Elon Musk has clarified that the Grok 4.3 Beta model is a 0.5 trillion parameter model, not the 1 trillion parameters as previously speculated. This clarification came after X user Mark Kretschmann posted incorrect information about the model's size. Musk, CEO of xAI and Tesla, stated that the 1 trillion parameter version is still in training and expected to be completed in five days. Musk also highlighted that the upcoming 1 trillion parameter model will significantly enhance coding, long-context handling, and overall capabilities. Additionally, he announced that the SpaceXAI model factory is now operational, with plans to release an improved base model every two weeks.
