Elon Musk announced a major adjustment on the X platform: his Grok Bot will no longer rely solely on the self-developed Grok series of models. Going forward, the system will take obtaining the best output results as its sole criterion, automatically selecting and invoking the most suitable backend model for users.
This means Grok Bot will shift toward a "task-oriented multi-model hybrid architecture," no longer limited to in-house or proprietary technology. When handling complex tasks involving text, images, or audio, it can flexibly call top-tier third-party APIs in the industry, including Claude Opus 5.5, Midjourney, and Suno.
An always-on cloud assistant, built to be an all-around AI colleague
As a beta product launched by SpaceXAI in August 2026, Grok Bot is positioned as the user's "always-on AI colleague." It can not only answer everyday questions but also automatically log into relevant applications on a cloud computer and independently complete multi-step operations, prompting for human approval only when critical decisions arise.
Each Grok Bot has its own dedicated name, clearly defined responsibilities, and continuously accumulated contextual memory, and users can issue instructions at any time via text or voice. Because it is deployed on cloud servers equipped with a browser, file system, and terminal, background tasks and scheduled work continue to run stably even when the user turns off their computer or phone.
