Technological Development

Grok started with a basic version, followed by Grok‑1.5, which added support for images and PDFs. The Grok‑2 model improved data processing speed, and in February 2025, Grok‑3 was released, trained on the Colossus supercomputer and capable of deeper analysis of medical, scientific, and technical tasks.
In July 2025, Grok‑4 was introduced, featuring a voice interface, coding mode, and an even more powerful context system.

Grok is available through X Premium, offering voice support and a context window of 128,000 tokens. The SuperGrok-Heavy version, with extended functionality and API access, costs $30 per month or $300 per year.
