Yi is a family of open-source large language models trained from scratch by 01.AI, including base and chat models in multiple sizes, with bilingual (English/Chinese) capabilities. The repository provides model weights, quick-start guides for pip, Docker, and llama.cpp, plus fine-tuning, quantization, and deployment resources.

Use cases

• run an open-source bilingual LLM locally
• fine-tune a large language model on my own data
• quantize an LLM for cheaper inference
• self-host a chat model with llama.cpp
• compare open LLM benchmarks before choosing a base model
• deploy an LLM behind an API

When to choose

• you need an Apache-2.0 licensed LLM you can self-host and fine-tune
• your application needs strong English-Chinese bilingual performance
• you want a base model to build a chat assistant or RAG pipeline on

When to avoid

• you need a managed hosted API without running your own infrastructure
• you need frontier-level reasoning beyond what mid-size open models offer
• you need multimodal (image/audio) input from the base model family
