xAI began rolling out Grok 4.7 to testers in mid-September 2026 after months of delays. The release continued xAI's strategy of competing on price as much as benchmarks, undercutting rivals rather than chasing outright benchmark leads.

The delays had frustrated Grok watchers, with Musk's promised timelines slipping repeatedly through 2026. The tester rollout suggested a wider release was close but not yet finalized.

Meanwhile Grok 5 — which Musk called 'AGI-class' on September 14 — remains unreleased with no date set, after missing its original Q4 2025 and Q1 2026 targets.
