7. 7 Core Capabilities Gemma 4 models handle a broad range of tasks across text, vision, and audio. Key capabilities include: • Thinking – Built-in reasoning mode that lets the model think step-by-step before answering. • Long Context – Context windows of up to 128K tokens (E2B/E4B) and 256K tokens (26B A4B/31B). • Image Understanding – Object detection, Document/PDF parsing, screen and UI understanding, chart comprehension, OCR (including multilingual), handwriting recognition, and pointing. Images can be processed at variable aspect ratios and resolutions. • Video Understanding – Analyze video by processing sequences of frames. • Interleaved Multimodal Input – Freely mix text and images in any order within a single prompt. • Function Calling – Native support for structured tool use, enabling agentic workflows. • Coding – Code generation, completion, and correction. • Multilingual – Out-of-the-box support for 35+ languages, pre-trained on 140+ languages. • Audio (E2B and E4B only) – Automatic speech recognition (ASR) and speech-to-translated-text translation across multiple languages GDG KR X MUG KR
