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++.

🔥 2024-09-05: The Yi-Coder series models are open sourced and available to the public.
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.txtYou can run Yi-Coder on Ollama locally.
-
After installing Ollama, you can start the Ollama service. Note that keep this service running while you use Ollama.
ollama serve
-
Run Yi-Coder models. For more Yi models supported by Ollama, see Yi tags.
ollama run yi-coder
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)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}")- System prompt: Enhance coding workflow with code completion, insertion, and quality assurance.

To ensure the fairness of our evaluation, we follow the official implementations to obtain the evaluation results for most of the benchmarks we considered, including LiveCodeBench, CRUXEval-O, CodeEditorBench, and CrossCodeEval. For HumanEval (zero-shot, multilingual), MBPP (3-shot), and 7 math programming tasks, we follow the widely adopted evaluation codebase released by DeepSeek-Coder.
