Zusammenfassung

Wir stellen Gemma 4 vor, eine neue Generation von offen gewichteten, nativ multimodalen Sprachmodellen der Gemma-Modellfamilie. Entwickelt, um Recheneffizienz und logisches Denken voranzutreiben, umfasst die Gemma-4-Modellreihe dichte und Mixture-of-Experts-Architekturen mit 2,3 bis 31 Milliarden Parametern. Neben verbesserten Bild- und Audio-Encodern für alle Modellgrößen schlagen wir für unser 12B-Modell eine einheitliche, encoderfreie Architektur vor, die rohe Audio- und Bild-Patches verarbeitet. Darüber hinaus integrieren wir einen Denkmodus, der es den Gemma-Modellen ermöglicht, vor der Antwortgenerierung Argumentationsspuren zu erzeugen. Durch kritische Designentscheidungen verbessern wir Inferenzgeschwindigkeit, Speicher- und Recheneffizienz sowie Fähigkeiten für lange Kontexte. Gemma 4 erzielt einen Leistungssprung bei Benchmarks in den MINT-Fächern, bei multimodalen und langen Kontexten und übertrifft in von Menschen bewerteten Aufgaben größere, führende Open-Weight-Modelle.

English

We introduce Gemma 4, a new generation of open-weight, natively multimodal language models in the Gemma model family. Designed to advance compute efficiency and reasoning, the Gemma 4 model suite features dense and Mixture-of-Experts architectures, ranging from 2.3B to 31B parameters. Alongside improved vision and audio encoders for all model sizes, we propose a unified, encoder-free architecture for our 12B model, which ingests raw audio and image patches. Furthermore, we integrate a thinking mode, enabling Gemma models to generate reasoning traces prior to responding. We improve inference speed, memory, and compute efficiency, as well as long-context abilities through critical design choices. Gemma 4 establishes a leap in performance across STEM, multimodal, and long-context benchmarks, and rivals larger, frontier open models in human-rated tasks.
