SmolVLM-256M-Instruct-Int8

This version of SmolVLM-256M-Instruct has been converted to run on the Axera NPU using w8a16 quantization.

This model has been optimized with the following LoRA:

Compatible with Pulsar2 version: 3.4-temp

 The image depicts a double decker bus, which is prominently displayed in the center of the image. The bus is red and has a large, bold sign on its roof that reads
"Things Get More Exciting When You Say So." The sign is in white text, and the bus is designed to be eye-catching and visually appealing.

The bus is parked on a city street, with a few other vehicles visible in the background. The street is lined with buildings, including a few shops and restaurants,
which are partially visible. The buildings are well-lit, and the street is clean and well-maintained.

In the foreground, there is a person standing in front of the bus. The person is wearing a dark jacket and appears to be waiting for the bus. The person is facing the bus,
and they seem to be waiting for the bus to arrive.

The bus is parked on the street, and it is not moving. The bus is not moving, and there are no other vehicles visible in the image. The street is well-maintained,
and the buildings are well-lit, indicating that it is a sunny day.

The image is taken from a slightly elevated perspective, which gives a clear view of the bus and the surrounding area. The lighting in the image is bright,
and the shadows are well-defined, indicating that the sun is shining brightly.

To summarize, the image depicts:
1. A double-decker bus with a large sign on its roof that reads "Things Get More Exciting When You Say So."
2. The bus is parked on a city street with a few other vehicles visible in the background.
3. The bus is not moving, and there are no other vehicles visible in the image.
4. The street is well-maintained, and the buildings are well-lit, indicating a sunny day.

This description provides a comprehensive overview of the image, allowing a text model to answer any questions related to the image based on the description.
