FastVLM-0.5B

This version of FastVLM-0.5B 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: 5.1-patch1.

Please note that the context of the 650 model is 1k and the maximum prefill length is 640 tokens, and the context of the 620e/630c model is 512 and the maximum prefill length is 256 tokens.

answer >> The image depicts a person riding a brown horse with a white blaze on its face. The rider is wearing a blue hoodie and blue jeans, and is holding the reins of the horse. The horse is standing on a dirt ground with some grass and trees in the background. The rider is also holding a rope in their left hand, which is attached to the horse's harness.

To the left of the horse, there is a brown dog standing on the ground, looking up at the rider. The dog appears to be in a begging or pleading position, with its front paws raised and its mouth open.

In the background, there is a gray pickup truck parked on the grass, and a wooden fence can be seen behind the horse and rider. There are also some people visible in the background, including a person in a red shirt and another person in a blue shirt. The overall scene appears to be taking place in an outdoor setting, possibly a ranch or a farm.

answer >> The image depicts a panda bear in a naturalistic enclosure, likely within a zoo or wildlife sanctuary. The panda is sitting on its hind legs, with its front paws resting on a wooden structure that resembles a tree stump. The panda's distinctive black and white fur is clearly visible, with the black fur covering its ears, eyes, and the area around its nose and mouth, while the white fur covers the rest of its body. The panda's black nose and the black fur around its mouth are also visible.

The panda is surrounded by green foliage, including bamboo shoots and other plants, which are typical of a panda's natural habitat. The ground appears to be covered with dirt and small rocks, and there are some larger rocks and a tree stump in the background. The lighting in the image suggests that it was taken during the daytime, with natural light illuminating the scene. The overall setting appears to be a well-maintained and naturalistic enclosure designed to mimic the panda's natural environment.
