##INT4:
## The image captures a serene moment at a beach during what appears to be sunset or sunrise. The sun casts a warm, golden hue over the scene. In the foreground, a woman sits on the sandy shore, facing a large, golden-colored dog. The dog, wearing a colorful harness, places one paw on the woman's hand, suggesting a bond or a playful gesture. The woman seems to be smiling, indicating a moment of joy or connection with the dog. The ocean waves gently crash in the background, and the horizon is visible, suggesting the vastness of the sea. The overall mood of the image is peaceful and heartwarming.
##BF16:
## The image showcases a serene beach setting during what appears to be either sunrise or sunset. In the foreground, a woman sits on the sandy beach, dressed in casual attire, including a checkered shirt and jeans. She is engaged in a moment of connection with a golden retriever dog, which is seated beside her. The dog wears a colorful harness and is looking up at the woman, possibly in anticipation of a treat or a playful gesture. The vast expanse of the ocean can be seen in the background, with gentle waves crashing onto the shore. The sky is clear, and the warm hues of the setting or rising sun cast a soft glow over the scene, creating a tranquil and heartwarming atmosphere.

--output_dir "./tmp_autoround"
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.
