xAI just closed a massive $6 billion Series B round backed by Sequoia Capital, Andreessen Horowitz, and others. The company plans to use the capital to launch its first commercial products, build advanced infrastructure, and accelerate future R&D. Following its Grok-1.5 and Grok-1.5V releases, xAI now has the war chest to stay in the frontier compute race.
xAI just released the base model weights and architecture of its Grok-1 language model under the permissive Apache 2.0 license.

Developers can now access instructions directly on GitHub.
