Elon Musk's SpaceXAI, formerly Eloncorp, launched Grok 4.5, an AI model rebranded for legal advice and Excel tasks. The model claims improved performance through training on Nvidia GB300 GPUs and Cursor acquisition, but independent benchmarks suggest it lags behind models like Anthropic’s Claude Fable.

SpaceXAI's new coding model Grok 4.5 is positioned as cheaper and faster than Anthropic and OpenAI's flagship models. Elon Musk claims it competes with last year's Claude Opus but acknowledges it is at least one generation behind those models.

OpenAI is launching its new GPT-5.6 AI model family, including Sol, Terra, and Luna, while Elon Musk announced the Grok 4.5 model from SpaceXAI. The developments coincide with ongoing rivalry between Musk and OpenAI CEO Sam Altman, following Musk's 2024 lawsuit over OpenAI's nonprofit status and a recent court loss.
