xAI, the artificial intelligence company founded by Elon Musk, has missed its target to release its next major AI model, Grok 3, by the end of 2024. The delay adds to a growing trend among AI companies struggling to meet their ambitious launch schedules. While xAI had promised that Grok 3 would be a significant advancement, trained on a Memphis-based cluster of 100k H100s GPUs, the model has not been released as of January 2, 2025. There are indications that an intermediate model, Grok 2.5, might be launched first. This situation reflects broader challenges in the AI industry, where traditional scaling methods are becoming less effective, and companies are exploring alternative techniques to enhance model performance.
