## About Qwen2.5-Coder

Qwen2.5-Coder's November 2024 release completed Alibaba Cloud's coding-model family with six sizes, from 0.5B to 32B parameters. It added 0.5B, 3B, 14B and 32B checkpoints to the earlier 1.5B and 7B models. Each size came in base and instruction-tuned forms, supporting both further training and direct use in programming assistants.

The family targeted code generation, repair and reasoning across programming languages. Deployment details varied by size: the smaller models supported 32K context, while the 7B, 14B and 32B tiers supported longer inputs up to 128K under the documented setup. Most sizes used Apache 2.0, with the 3B model under the Qwen Research License. The release therefore offered several distinct hardware and licensing choices.
