How we got this
IBM is the maker of Granite 4.2. We look at the gaps between its earlier versions (Granite 4.2, 2026-08-31) and project the next one. It is a guess from a pattern, not news: the maker has not said Granite 4.3 exists. This page turns into the launch page, with price and facts, as soon as the model shows up on OpenRouter, Hugging Face or GitHub.
