01.AI has released several iterations of its Yi models, with varying context window sizes and licensing terms. Initially released in November 2023, the Yi-6B and Yi-34B models featured a 4,096 token context window and a community license requiring registration for commercial use. Subsequent releases, including long-context variants like Yi-6B-200K and Yi-34B-200K, offered up to 200,000 tokens. The licensing was later updated to the more permissive Apache 2.0 license for all models, including the newer Yi-1.5 generation released in May 2024, aligning them with other open-weight models. AI
