Elon Musk said SpaceX planned to release a brand-new artificial intelligence model every month for the rest of this year. According to Jin10, Musk wrote on X that the latest generation large language model, Grok 4.5, had officially begun beta testing inside SpaceX and Tesla, and would be rolled out more broadly afterward.
Musk added that SpaceX intended to publish a new AI model each month for the remainder of the year, describing each release as a model “trained completely from scratch.” He indicated that future versions might not be simple upgrades to existing systems, but newly trained foundation models built through fresh training.
