Grok 4.5 Release: AI Race Intensifies With GPT-5.6, Fable 5

Elon Musk's SpaceXAI will release its new AI model, Grok 4.5, to the public tomorrow. This model is described as Opus-class, but faster, more token-efficient, and lower cost. It runs on V9, xAI’s new 1.5-trillion-parameter foundation model, which is roughly three times the size of the architecture behind Grok 4.3. What's interesting is that OpenAI also plans to launch its GPT-5.6 Sol, along with Terra and Luna, tomorrow. This intensifies the AI race, especially with the recent launch of Anthropic’s Fable 5. Grok 4.5 is the largest model SpaceXAI has shipped, trained on Blackwell GPUs. Coding is a clear focus for this AI model. The bottom line is that the competition in artificial intelligence is rapidly advancing with multiple major releases happening simultaneously.
