xAI has paused hiring for a category of specialist trainers it calls “AI tutors,” according to people familiar with the matter. Since early 2026, the company had been actively recruiting accountants, financial experts, scientists, and even comedians to teach Grok how to perform better across domains ranging from tax advice to humor — an approach that set xAI apart from rivals, which typically rely on large pools of contract workers from third-party firms for model training and fine-tuning. The pause is at least partly driven by concerns that xAI’s HR department was becoming overwhelmed by the volume of recruiting work, the people said.
The freeze comes against a backdrop of recurring workforce changes at xAI. The company cut several AI tutors last autumn — many of them generalists — and then shifted toward recruiting workers with narrower data annotation specializations. A further round of layoffs followed in early March 2026, affecting the AI tutor team as well as other departments. Taken together, the moves suggest xAI may be rethinking its differentiated, in-house training model and edging toward more automated or contractor-based data pipelines closer to industry standard practice.
