xAI — AI Glossary

xAI is the artificial intelligence research company founded by Elon Musk in 2023. The company builds the Grok family of large language models and the Aurora image generation model, with a stated focus on real-time information access and a less restricted response style than its major competitors. xAI integrates Grok directly into X (formerly Twitter), giving its models ambient access to the platform's live post stream — a capability no other major AI lab offers at the consumer level.
