In this episode of Model Behavior, we analyze the major shifts in the AI model landscape as of July 9th, 2026. We lead with SpaceXAI—formerly xAI—and its release of Grok 4.5. This model marks the first tangible output of the company’s $60 billion acquisition of Cursor and utilizes tens of thousands of Nvidia GB300 GPUs. We examine the economic disruption Musk is attempting by pricing Grok 4.5 significantly lower than OpenAI’s GPT-5.6 and Anthropic’s Claude 4.7. We also deep-dive into OpenAI’s new GPT-Live-1 voice models, which offer simultaneous translation and more natural human-like interaction. Finally, we look at the corporate convergence of Salesforce and Slack, and Anthropic’s mathematical inquiry into the internal 'workspace' of large language models.
