Pretty good chance that Grok 4.6 could surpass Fable 5 at solving complex problems and handling real-world tasks Elon Musk recently said SpaceXAI is closing the loop on solving real-world engineering problems across Tesla, SpaceX, Neuralink and The Boring Company The next Grok release is going to be a very big jump Additionally, SpaceXAI is developing its own C/C++ inference software from the ground up, mapped directly to GB300 hardware Elon said it could double output speed or potentially deliver an even greater improvement And remember, SpaceXAI has built one of the most highly optimized AI infrastructure on Earth That efficiency advantage could eventually reach users through faster responses, more generous usage limits and lower costs SpaceXAI is optimizing every layer of the AI stack for maximum intelligence, speed and efficiency: • Frontier models • Real-world engineering feedback • Highly optimized data centers • Custom training infrastructure • Ground-up inference software • Token and cost efficiency This could bring a huge jump in intelligence, real-world usefulness, agentic performance, speed and efficiency
