Instructions to use BabyChou/Yi-VL-34B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use BabyChou/Yi-VL-34B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="BabyChou/Yi-VL-34B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForCausalLM

processor = AutoProcessor.from_pretrained("BabyChou/Yi-VL-34B")
model = AutoModelForCausalLM.from_pretrained("BabyChou/Yi-VL-34B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

What is Yi-VL?

Architecture

Yi-VL adopts the LLaVA architecture, which is composed of three primary components:

Vision Transformer (ViT): it's initialized with CLIP ViT-H/14 model and used for image encoding.
Projection Module: it's designed to align image features with text feature space, consisting of a two-layer Multilayer Perceptron (MLP) with layer normalizations.
Large Language Model (LLM): it's initialized with Yi-34B-Chat or Yi-6B-Chat, demonstrating exceptional proficiency in understanding and generating both English and Chinese.

How to use Yi-VL?

Quick start

This has been implemented into the SGLang codebase, where you can simply call this model by creating a function like so:

import sglang as sgl

@sgl.function
def image_qa(s, image_path, question):
    s += sgl.user(sgl.image(image_path) + question)
    s += sgl.assistant(sgl.gen("answer"))


runtime = sgl.Runtime(model_path="BabyChou/Yi-VL-34B",
                      tokenizer_path="BabyChou/Yi-VL-34B")
sgl.set_default_backend(runtime)


# Single
state = image_qa.run(
    image_path="images/cat.jpeg",
    question="What is this?",
    max_new_tokens=64)
print(state["answer"], "\n")
