xAI's accelerated release cadence for Grok models, with Grok 4.7 shipping publicly on September 21 just weeks after 4.6, drives trader expectations for a swift 4.8+ follow-up. The company, now operating under the SpaceXAI brand, continues emphasizing large-scale post-training on coding and long-horizon agentic tasks, delivering strong price-performance at $2/$6 per million tokens alongside integrations in Cursor, GitHub Copilot, and Grok Build. Competitive pressure from Claude and GPT variants on benchmarks like CursorBench and SWE-Bench keeps the focus on iterative gains rather than single leapfrog releases. No official 4.8 timeline has emerged yet, though the pattern of sub-40-day gaps between recent versions and ongoing infrastructure expansions suggest potential movement before year-end.
