StarCoder2 and The Stack v2

StarCoder2 has been released as a new code generation model, built on the foundations of the original StarCoder, and trained on The Stack v2 dataset, which includes a diverse range of programming languages and frameworks. The model features 16 billion parameters and demonstrates improved performance on code completion tasks, achieving state-of-the-art results on the HumanEval benchmark. This release is significant for practitioners as it enhances code generation capabilities, enabling more efficient development workflows and better integration into AI-driven development environments.
