BigCode

BigCode is an open scientific collaboration working on responsible training of large language models for coding applications. You can find more information on the main website or follow Big Code on Twitter. In this organization you can find the artefacts of this collaboration: StarCoder 2, a state-of-the-art language model for code, and the previous StarCoder family of models, The Stack, the largest available pretraining dataset with perimssive code, Astraios, scaling instruction-tuned language models for code via diverse fine-tuning methods, OctoPack, artifacts for instruction tuning large code models, and SantaCoder, a 1.1B parameter model for code.

💫StarCoder 2 StarCoder2 models are a series of 3B, 7B, and 15B models trained on 3.3 to 4.3 trillion tokens of code from The Stack v2 dataset, with over 600 programming languages. The models use GQA, a context window of 16,384 tokens with a sliding window attention of 4,096 tokens, and were trained using the Fill-in-the-Middle objective.

Models

  • Paper: A technical report about StarCoder2.
  • GitHub: All you need to know about using or fine-tuning StarCoder2.
  • StarCoder2-15B: 15B model trained on 600+ programming languages and 4.3T tokens.
  • StarCoder2-7B: 7B model trained on 17 programming languages for 3.7T tokens.
  • StarCoder2-3B: 3B model trained on 17 programming languages for 3.3T tokens.

Data & Governance

📑The Stack v2 The Stack v2 is a 67.5TB dataset of source code in over 600 programming languages with permissive licenses or no license.
💫StarCoder StarCoder is a 15.5B parameters language model for code trained for 1T tokens on 80+ programming languages. It uses MQA for efficient generation, has 8,192 tokens context window and can do fill-in-the-middle.
