About Yi-Lightning
Yi-Lightning is 01.AI's mid-tier model with particular strength on Chinese tasks. It briefly held strong placements on LMSYS Arena's overall leaderboards in late 2024 before larger labs caught up.
The extremely flat $0.14 / 1M token price (input or output) makes it one of the cheapest first-tier models on the market and a popular pick for Chinese-language production deployments.
