xAI launches Grok 4.6, previews Grok 4.7 supplemental training on SpaceX engineering data
xAI on Aug 19 launched Grok 4.6, with Musk noting Grok 4.7 is expected in mid-September; Grok 4.7 will train on SpaceX internal engineering data to strengthen software engineering capability.
xAI launched Grok 4.6 on August 19, 2026. The same day Elon Musk announced on X that Grok 4.7 is coming soon, with a mid-September window per published docs.x.ai cadence.Grok 4.7 will run supplemental training on SpaceX internal engineering data, with a focus on strengthening software engineering capability. Following the SpaceX integration, Musk's companies are assembling an engineering-specific AI stack spanning model, editor, and Agent.The ecosystem buildout includes SpaceX's roughly $60 billion acquisition of Cursor parent Anysphere (closed Aug 14) and SpaceX's approach to Cognition (Devin parent) about acquisition and compute partnerships.Grok 4.6 is an iteration of the Grok 4 series, focused on real-time information access and base reasoning capability. The meaningful story in this batch is less the model itself and more Musk's engineering AI integration.
