Musk: 2T-parameter Grok finishes training this month, ships in August

Elon Musk says xAI's next Grok model — a 2 trillion parameter system — is in the final stretch of training and should wrap by late July, with a public launch penciled in for August.

That's a big step up. The current production Grok runs on roughly 1.5T parameters (the "V9" foundation), so the new model is a ~33% size bump. It's being trained on xAI's Colossus supercluster in Memphis, now packing 200,000+ NVIDIA GPUs. Musk has floated an aggressive cadence: brand-new models trained from scratch, shipping roughly monthly through the rest of 2026.

Worth the usual asterisk: xAI's flagship timelines have slipped repeatedly, and "finishes this month" isn't the same as "benchmarks that beat GPT and Claude." Parameter count is a capacity ceiling, not a quality guarantee — and xAI still hasn't published a model card to back the numbers.

Why it matters: if the August drop lands on schedule, the frontier race just added a monthly release clock — and everyone else has to keep pace.
