Intro

Yi-Coder is a series of open-source code language models that delivers state-of-the-art coding performance with fewer than 10 billion parameters.

Key features:

  • Excelling in long-context understanding with a maximum context length of 128K tokens.
  • Supporting 52 major programming languages, including popular ones such as Java, Python, JavaScript, and C++.

News

🔥 2024-09-05: The Yi-Coder series models are open sourced and available to the public.

Quick Start

Requirements

Make sure you have python>=3.9 installed before using it. To set up the environment and install the requirements, run the following command:

git clone https://github.com/01-ai/Yi-Coder.git
cd Yi-Coder
pip install -r requirements.txt

Ollama

You can run Yi-Coder on Ollama locally.

  1. After installing Ollama, you can start the Ollama service. Note that keep this service running while you use Ollama.

    ollama serve

  2. Run Yi-Coder models. For more Yi models supported by Ollama, see Yi tags.

    ollama run yi-coder

Transformers

You can use transformers to run inference with Yi-Coder models (both chat and base versions) as follows:

from transformers import AutoTokenizer, AutoModelForCausalLM

device = "cuda" # the device to load the model onto
model_path = "01-ai/Yi-Coder-9B-Chat"

tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(model_path, device_map="auto").eval()

prompt = "Write a quick sort algorithm."
messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(device)

generated_ids = model.generate(
    model_inputs.input_ids,
    max_new_tokens=1024,
    eos_token_id=tokenizer.eos_token_id  
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)

vLLM

You can also use vLLM to reason about Yi-Coder models. vLLM is a fast and easy-to-use library for reasoning about and serving large language models (LLMs). Be sure to install vLLM and then do the following

from transformers import AutoTokenizer
from vllm import LLM, SamplingParams
model_path = "01-ai/Yi-Coder-9B-Chat"

tokenizer = AutoTokenizer.from_pretrained(model_path)

sampling_params = SamplingParams(
    temperature=0.8,
    top_p=0.8)

llm = LLM(model=model_path, 
          gpu_memory_utilization=0.9, 
          max_model_len=1024)

prompt = "Write a quick sort algorithm."  
messages = [
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
print(text)

# Generate the response
outputs = llm.generate([text], sampling_params)

# Print the output
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")
