Provides calibrated probabilistic decisions (yes/no, 2–256 choice, 0–5 score) in one forward pass, with an optional adaptive-thinking mode that invokes Gemma‑4 when System 1 is uncertain; supports text+image, 256K context and vLLM serving, but adaptive thinking is much slower.
Processes English and German text with long-context reasoning and structured tool-calling. Uses a 78B mixture-of-experts architecture that activates ~3.46B parameters per token, offers native 262k-token context (validated to 1M), and is released as Apache-2.0 weights — suited for RAG, document processing and human-in-the-loop decision support.
