 ## 0. Requirements
 To run these examples with IPEX-LLM on Intel GPUs, we have some recommended requirements for your machine, please refer to [here](../../../README.md#requirements) for more information.
 
-## Example: Multi-turn chat centered around an image using `generate()` API
-In the example [generate.py](./generate.py), we show a basic use case for a LLaVA model to start a multi-turn chat centered around an image using `generate()` API, with IPEX-LLM INT4 optimizations on Intel GPUs.
+## Example: Predict Tokens using `generate()` API
+In the example [generate.py](./generate.py), we show a basic use case for a LLaVA model to predict the next N tokens using `generate()` API, with IPEX-LLM INT4 optimizations on Intel GPUs.

-In the example, several arguments can be passed to satisfy your requirements:
-
-- `--repo-id-or-model-path REPO_ID_OR_MODEL_PATH`: argument defining the huggingface repo id for the LLaVA model (e.g. `liuhaotian/llava-v1.5-7b` to be downloaded, or the path to the huggingface checkpoint folder. It is default to be `'liuhaotian/llava-v1.5-7b'`.
-- `--image-path-or-url IMAGE_PATH_OR_URL`: argument defining the input image that the chat will focus on. It is required.
-- `--n-predict N_PREDICT`: argument defining the max number of tokens to predict. It is default to be `512`.

-USER: Do you know who drew this painting?
-ASSISTANT: Yes, the painting is a portrait of a woman by Leonardo da Vinci. It's a famous artwork known as the "Mona Lisa."
-USER: Can you describe this painting?
-ASSISTANT: The painting features a well-detailed portrait of a woman, painted in oil on a canvas. The woman appears to be a young woman staring straight ahead in a direct gaze towards the viewer. The woman's facial features are rendered sharply in the brush strokes, giving her a lifelike, yet enigmatic expression.
-The background of the image mainly showcases the woman's face, with some hills visible in the lower part of the painting. The artist employs a wide range of shades, evoking a sense of depth and realism in the subject matter. The technique used in this portrait sets it apart from other artworks during the Renaissance period, making it a notable piece in art history.

-If you encounter the following output, it means your machine has some trouble accessing huggingface.co.
-```log
-requests.exceptions.SSLError: (MaxRetryError("HTTPSConnectionPool(host='huggingface.co', port=443): Max retries exceeded with url: /openai/clip-vit-large-patch14-336/resolve/main/config.json (Caused by SSLError(SSLZeroReturnError(6, 'TLS/SSL connection has been closed (EOF) (_ssl.c:1129)')))"),

+The sample input image is (which is fetched from [COCO dataset](https://cocodataset.org/#explore?id=264959)):
 
-You can resolve this problem with the following steps:
-1. Download https://huggingface.co/openai/clip-vit-large-patch14-336 on some machine that can access huggingface.co, and put it in huggingface's local cache (default to be `~/.cache/huggingface/hub`) on the machine that you are going to run this example.
-2. Set the environment variable (`export TRANSFORMERS_OFFLINE=1`) before you run the example.
