xAI has yet to release Grok 5 as of mid-June 2026, with the large language model still in active training on the Colossus supercluster after earlier Q1 and Q2 2026 targets slipped. Recent focus has shifted to rapid iterations on the Grok 4 series, including the April 2026 Grok 4.3 beta and new multimodal tools like Grok Imagine Video 1.5, alongside API expansions on Amazon Bedrock. Trader sentiment reflects this pattern of delays and incremental updates rather than a major model launch, tempered by competitive pressure from other AI labs and uncertainty around when training will complete for a public beta or full release. Key near-term catalysts include any end-of-June announcements or confirmation of Q3 timelines.
