Musk says 2-trillion-parameter Grok 4.6 ships in weeks, Grok 4.7 to follow

Musk announced that Grok 4.6, a 2-trillion-parameter model that has finished pretraining, will ship in about two weeks and could 'exceed' Moonshot's Kimi K3, with Grok 4.7 following roughly four weeks later. A back-to-back major-release cadence at this scale is something no frontier lab has matched, and it is classic xAI positioning: promise the fastest cadence and the biggest parameter count.

The developer reaction split predictably between hype over an unmatched release pace and doubt grounded in track record: Grok 4.5 — priced at $2 per million input and $6 per million output — remains locked in private beta inside SpaceX and Tesla, so skeptics question whether 4.6 and 4.7 will actually reach general availability on Musk's timeline. Parameter count (2T) is also an increasingly weak proxy for capability as the field optimizes for efficiency and cost-per-task, the very axis on which Opus 5, Gemini 3.6 Flash and DeepSeek V4 competed this week.

xAI also shipped a Microsoft Excel Grok plug-in aimed at finance workflows — a niche but concrete enterprise move — and the week's separate Grok Voice Think Fast 2.0 release targeted voice agents. Internally, Bloomberg reported restructuring with Starlink executive Michael Nicolls now serving as xAI President, amid a disclosed Q1 2026 loss of $2.4 billion.

What to watch: whether Grok 4.6 actually launches publicly in two weeks (Musk timelines historically slip) and whether it benchmarks against, not just claims to 'exceed,' Kimi K3. The combination of aggressive roadmap promises, heavy losses, leadership churn and legal battles (see the Minnesota suit) makes xAI's execution the open question behind the bravado.
