Gemma 4 31B Gembrain X Core: Nimbz’s rebuilt Gembrain · a ground-up successor to Gembrain 31B
Gemma 4 31B Gembrain X Core is Nimbz's ground-up rebuild of Gembrain 31B (its card, created 2026-06-30), which the card calls Nimbz's most sophisticated multi-step merge yet: four pillars of Gemma 4 31B tunes joined through two convergence steps. The card describes two modes: thinking off for fast general use, light roleplay and image prompts, thinking on for stricter adherence to a character or prompt structure. X Core leaves out the final abliteration step that Gembrain X has. It is served as gemma-4-31b-gembrain-x-core at $1.071 input and $1.071 output per million tokens, one of 146 builds in the uncensored LLM API, on the same key as every other model. Added 2026-10-20.
