Elon Musk's newly rebranded SpaceXAI is rolling out its Grok 4.5 AI model on July 9.
This next-generation Opus-class chatbot promises smoother performance, smarter responses, and lower costs, building on the big improvements seen with Grok 4.3 earlier this year.

The switch from xAI to SpaceXAI highlights a closer tie-in with Musk's rocket company, complete with a new logo that mixes both brands' vibes.
