The bridge is a deep red color and is supported by two large towers. The water is a calm, dark blue, and there are some small waves. The building in the foreground is made of tan bricks and has several windows. In the foreground, there is a large rock in the water, and a small bird is perched on top of it. The sky is a clear, light blue. The sun is shining brightly, casting a soft light on the scene.', 'role': 'assistant'}

Sunlight is made of all colors\nEven though sunlight looks white to us, it is actually made up of all the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet. Each color travels as a wave with a different **wavelength**.\n*   **Red light** has long, lazy waves.\n*   **Blue and violet light** have short, choppy waves.\n\n### 2. The atmosphere acts as an obstacle\nEarth is surrounded by an atmosphere filled with nitrogen and oxygen gases. When sunlight enters the atmosphere, it hits these gas molecules and scat in all directions.\n\n### 3. Short waves scatter more\nBecause red and yellow light have long wavelengths, they pass through the atmosphere mostly without hitting anything. However, because **blue travels travels in shorter waves**, it crashes into the gas molecules and gets \"scattered\" in every direction. \n\n### 4.

Generate the Model

https://github.com/intel/auto-round/pull/1935 is required

auto-round-best --model /models/diffusiongemma-26B-A4B-it/ --scheme "W4A16" --group_size 64 --output_dir ./diffusiongemma_int4/

Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Therefore, before deploying any applications of the model, developers should perform safety testing.

Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
