Model details

Gemma 4 26B A4B IT

Gemma 4 26B A4B IT is part of the Gemma 4 family of open models built by Google DeepMind and released under the Apache 2.0 license, with both pre-trained and instruction-tuned variants distributed through Hugging Face. The family spans five sizes (E2B, E4B, 12B, 26B A4B, and 31B) and combines Dense and Mixture-of-Experts architectures, giving developers a range of options for deployment across phones, laptops, and servers. All Gemma 4 models are designed as capable reasoners with configurable thinking modes and maintain multilingual support across over 140 languages.

The 26B A4B variant stands out as the family's MoE configuration, with roughly 25.2 billion total parameters but only about 3.8 to 4 billion activated per token, achieving near the quality of the dense 31B model at substantially lower compute cost. It is built on 30 layers with a 1024-token sliding-window hybrid attention mechanism and supports a 256K-token context window, making it well suited for long-document analysis and agentic workflows. The model accepts text and image input and produces text output, and it is optimized for efficient execution of coding, reasoning, and tool-driven tasks on resource-constrained hardware.

This Simplismart deployment-focused article targets the Gemma 4 26B MoE variant by name, framing it as delivering near-flagship 31B-level performance at roughly 4B-parameter active inference cost. The piece discusses the MoE routing mechanism, contrasts the 26B-A4B against the 31B dense flagship across reasoning and vi As a third-party provider blog with deployment framing rather than a first-party Google announcement, the article is useful as independent corroboration of the 26B-A4B variant's active-parameter architecture and single-GPU deployability rather than as breaking news.
