 The **Yi** series models are large language models trained from scratch by
-developers at [01.AI](https://01.ai/). The first public release contains two
-bilingual (English/Chinese) base models with the parameter sizes of 6B and 34B.
-Both of them are trained with 4K sequence length and can be extended to 32K
-during inference time.
