Brian Wang Elon Musk had talked about getting XAI Grok 4.20 out by the end of 2025. It has now been pushed back to mid-February. It will be two months late (or more). It has more training so it will likely be a better model than what would have been released two months ago. There is also XAI Grok 5, which was originally planned for March 2026. The XAI Grok 5 model will likely be delayed to April to June 2026. There is talk that XAI will merge with SpaceX. This likely happens as two private companies merging like Elon merged X (aka Twitter) with XAI. We had some power uptime issues due to the extremely cold weather and some construction equipment taking out power lines. As a result, Grok 4.20 training is a few weeks delayed to mid Feb.
