YAYI 2 is a family of open-source multilingual large language models (30B Base and Chat variants) developed by Wenge Research, pretrained on over 2 trillion tokens with a focus on Chinese. The repository provides model weights, inference code, fine-tuning scripts (full-parameter and LoRA), and a 500GB pretraining dataset.

Use cases

• run a chinese open-source llm locally
• download pretrained 30b language model weights
• finetune a chinese llm with lora
• chat with a chinese gpt-style model
• get multilingual llm pretraining data
• evaluate llm on c-eval and mmlu benchmarks

When to choose

• you need a strong open-source Chinese-language LLM with permissive Apache-2.0 code licensing
• you want to fine-tune a 30B model with provided LoRA or full-parameter training scripts
• you need multilingual pretraining data for LLM research

When to avoid

• you need a small model that runs on consumer hardware
• you require the Chat variant, which was not fully released at last update
• you need a commercially permissive model license (model weights use a custom YAYI license, data is CC BY-NC 4.0)
