Why xAI Grok-1 matters for businesses
For most businesses, Grok-1 was too large and too raw to use directly, since it needed multi-GPU servers and further tuning. Its significance was that a frontier-scale lab released a big model under a fully permissive license, adding pressure on others to open up.
