pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("prithivMLmods/gemma-4-31B-it-qat-FP8")

gemma-4-31B-it-qat-FP8

google/gemma-4-31B-it-qat-q4_0-unquantized is a 31-billion-parameter instruction-tuned multimodal model from Google DeepMind, optimized using Quantization-Aware Training (QAT) and released in an unquantized Q4_0 checkpoint format for research, custom compilation, and downstream quantization workflows. The model supports text and image inputs with text generation outputs, features a 256K-token context window, native reasoning ("thinking") capabilities, function calling, multilingual support across 140+ languages, and strong performance in coding, reasoning, document understanding, and long-context tasks. Unlike the GGUF release, this checkpoint preserves the QAT-trained weights before final deployment quantization, making it particularly suitable for experimentation with custom inference engines, FP8/NVFP4 quantization, and production optimization frameworks while maintaining quality close to the original high-precision model.
