Gemma 4 26B A4B IT

Overview

Gemma 4 26B A4B IT is an instruction-tuned variant of Google's Gemma 4 model family, offering 26 billion parameters and a 262,000-token context window. As an open-weight model available through OpenRouter and for self-hosted deployment, it provides engineering teams with full control over their AI infrastructure — a key consideration for organisations with data sovereignty, compliance, or cost requirements.

Released in April 2026, it performs strongly on general-purpose instruction following, long-context summarisation, and reasoning tasks, making it a capable backbone for on-premise dependency tooling and engineering assistant applications.
