Architecture, strengths and use cases
Gemma 4 26B-A4B IT is an official self-hostable Google release in the Gemma General track. It uses Gemma4ForConditionalGeneration, carries 25.8B / 4B MoE, supports a verified context window of 262,144 tokens, and exposes only source-certified checkpoints and runtime combinations. Its release, license and deployment facts are tied to the official repository revision rather than inferred from the family name.
Gemma 4 26B-A4B IT uses Gemma4ForConditionalGeneration with 25.8B / 4B MoE. The stored architecture profile records 30 layers, hidden width 2816, 16 attention heads and a 262,144 token context ceiling where the official configuration publishes those fields.
