Elon Musk announced on social media platform X today that the early test version of Grok 3.5 will be available to SuperGrok subscribers next week. Its key breakthrough lies in the first-time ability to provide precise answers to questions in specialized fields such as rocket engine design and electrochemical technology, while generating original answers not found on the internet through "first principles reasoning."

Musk revealed that the official version of Grok 3.5 will be accessible to the public in the third quarter of 2025. Additionally, an enterprise-level API service is planned for release, targeting clients like aerospace companies, energy firms, and materials science laboratories.
