xAI

The company builds large language models and has been unusually public about constructing its own computing infrastructure rather than renting all of it. Its assistant product is distributed in part through the social platform X, which gives it a route to users that most competitors have to buy.

Brimco follows xAI as part of a wider question about the artificial intelligence market: whether the field settles into a handful of large model providers, and what it costs to enter it late.
