Momentum
Yi-34B is an open, bilingual (English/Chinese) base language model with 34 billion parameters, trained from scratch by 01.AI (Beijing, founded by Kai-Fu Lee). It is based on the Llama architecture but is not a Llama derivative, and was pretrained on a 3-trillion-Token corpus. At release, the model achieved top-tier scores among open models on Benchmarks such as the Hugging Face Open LLM Leaderboard and C-Eval; a variant with a 200K context window was released shortly after. Yi-34B is available under a proprietary license (Yi Series Models Community License, also partially under Apache-2.0 for subsequent versions) with free commercial use upon application.
