Starcoderbase

🚀 StarCoderBase

StarCoderBase is a powerful model trained on 80+ programming languages, enabling code generation and fill - in - the - middle tasks.

🚀 Quick Start

Play with the model on the StarCoder Playground.

✨ Features

The StarCoderBase models are 15.5B parameter models trained on 80+ programming languages from The Stack (v1.2), with opt - out requests excluded. The model uses Multi Query Attention, a context window of 8192 tokens, and was trained using the Fill - in - the - Middle objective on 1 trillion tokens.

📦 Installation

The installation steps mainly involve installing the transformers library.

pip install -q transformers

💻 Usage Examples

Basic Usage

# pip install -q transformers
from transformers import AutoModelForCausalLM, AutoTokenizer

checkpoint = "bigcode/starcoderbase"
device = "cuda" # for GPU usage or "cpu" for CPU usage

tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = AutoModelForCausalLM.from_pretrained(checkpoint, trust_remote_code=True).to(device)

inputs = tokenizer.encode("def print_hello_world():", return_tensors="pt").to(device)
outputs = model.generate(inputs)
print(tokenizer.decode(outputs[0]))

Advanced Usage

Fill - in - the - middle uses special tokens to identify the prefix/middle/suffix part of the input and output:

input_text = "<fim_prefix>def print_hello_world():\n    <fim_suffix>\n    print('Hello world!')<fim_middle>"
inputs = tokenizer.encode(input_text, return_tensors="pt").to(device)
outputs = model.generate(inputs)
print(tokenizer.decode(outputs[0]))

Attribution & Other Requirements

⚠️ Important Note

The pretraining dataset of the model was filtered for permissive licenses only. Nevertheless, the model can generate source code verbatim from the dataset. The code's license might require attribution and/or other specific requirements that must be respected. We provide a search index that let's you search through the pretraining data to identify where generated code came from and apply the proper attribution to your code.
