xAI introduced Grok Voice Transcribe 2.0 as its most accurate speech-to-text model, claiming twice the accuracy of version 1.0 at the same $0.10/hour batch and $0.20/hour streaming price, per the lab’s announcement.
On 28 September 2026 Amazon announced that xAI’s Grok 4.7 is available on Bedrock: a 500K-token context window, four reasoning-effort levels (low, medium, high, xhigh), image input, and Geo and Global inference profiles. AWS frames it for coding, long-running agents and knowledge work, via Responses, Chat Completions and Converse APIs.
xAI adopts the official name SpaceXAI per Mashable and other outlets, strengthening brand linkage to SpaceX and complicating—or clarifying—its appearance in lawsuits and contracts.
New Scientist on September 11, 2026 reports that Colossus 2 in Tennessee—the largest operational U.S. data center serving xAI/SpaceXAI AI—centers an environmental debate: satellite analysis suggests a NOx spike tied to dozens of temporary gas turbines in Mississippi. The company promised to remove 69 temporary turbines by July 2027 and replace them with 41 permanent ones (MDEQ permit March 2026). Company and local authorities dispute the claims. Verification disputed. We prefer xAI / Colossus 2 naming; press sometimes says SpaceXAI.
On September 2, 2026, Elon Musk estimated Grok 4.7 in about 10 days (~September 12). On September 11 he announced a delay (“a few more days”): RL may have penalized response length too aggressively and the model shows weak self-checking. Grok 4.6 remains current; no new fixed date.

Elon Musk’s xAI launched Grok inside X, betting on a distinct personality and realtime social data.
