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.
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.
