Elon Musk’s xAI launched Grok inside X, betting on a distinct personality and realtime social data.
xAI presented Grok as an assistant with a more irreverent tone and connection to X posts. Later iterations sought frontier parity in reasoning and code.
Competition added salary and GPU pressure in the researcher labor market. It also polarized moderation and bias debates.
More frontier labs meant more product diversity—and a fiercer race for talent and energy.
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.

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 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.
