Yi
01.AI's open-weight large language model family (Yi-6B/9B/34B, including 200K-context variants), released under Apache 2.0 for commercial and research use; also served through 01.AI's own hosted platform, platform.lingyiwanwu.com, whose playground access is by whitelist application rather than public self-serve.
Weights published under Apache 2.0 on GitHub (01-ai/Yi) and Hugging Face/ModelScope/WiseModel, no charge. 01.AI's own hosted platform (platform.lingyiwanwu.com) exists but its playground is gated by a whitelist application, not a published self-serve rate -- checked 2026-09-11, no pricing page found.
