Yi-Coder

Open-source code large language model Y Voice & Memory

Basic Information

Product Description

Yi-Coder is an open-source code language model series launched by 01.AI (founded by Kai-Fu Lee), achieving industry-leading coding performance with fewer than 10 billion parameters. It excels in code generation, code editing, debugging, and even mathematical reasoning, supporting 52 major programming languages, with a maximum context length of 128K Tokens.

Yi-Coder-9B is built on Yi-9B and trained on an additional 2.4 trillion high-quality Tokens, sourced from GitHub's repository-level code corpus and code-related data filtered from CommonCrawl.
