Elon Musk's AI Startup xAI Seeks $1 Billion in Funding


On October 7th, Musk announced on X that Grok Bot has undergone a major adjustment in its underlying logic: this always-on AI colleague no longer solely relies on SpaceXAI's in-house Grok series, but will automatically select the best backend model based on specific tasks. It will be able to call leading APIs such as Claude Opus5.5, Midjourney, and Suno, with the sole criterion being the most likely result for users. Its technical strategy is shifting from primarily using in-house models to selecting the best models from multiple sources.
On September 28, xAI launched Team Bots, a type of Grok agent that works alongside teams and learns with them. After granting access to the necessary files, applications, and expertise and sharing them, all team members can collaborate based on the same context, while personal chats remain private. Each Team Bot is built around a shared role or workflow within the team, composed of four key capabilities, emphasizing context provision.
Musk predicts AI will double US GDP growth next year from ~2% to 4%+, diverging from mainstream views. Morningstar expects slowdown by 2027 with Fed hikes adding uncertainty; Apollo sees AI capex reaching 3% of GDP in 2027-2029; Moody's flags US tech chip spending in 2027.....
On Sep 16, 2026, xAI launched a memory feature in Grok Build to stop developers from repeating project architecture and coding standards each session. It automatically carries over core decisions and project facts, runs silently in the background, and updates after every turn.....
Musk announced on the X platform that the Grok 4.7 model will be launched within 10 days, with an expected release date of September 12, 2026. The model has a parameter scale of 2.1 trillion, which is a 40% increase compared to the previous version Grok4.6, with 1.5 trillion parameters, indicating xAI's accelerated efforts in parameter scale and performance iteration. The tweet also mentioned service speed details, but specific information has not been fully disclosed.
