Doubao Pro vs Yi-Lightning
How do these models stack up? Below is an expert side-by-side comparison of specifications, context window capacity, live pricing per million tokens, and standardized benchmark scores for Doubao Pro and Yi-Lightning.
Doubao Pro
Doubao Pro (θ±ε Pro) is ByteDance's flagship large language model, powering the Doubao AI assistant used by over 100 million monthly active users in China. Built by ByteDance's Seed team, Doubao Pro achieves top-tier results on Chinese-language benchmarks, excelling at long-context understanding, multimodal reasoning, and creative writing. Its architecture is optimized for the massive scale of ByteDance's inference infrastructure, enabling cost-efficient deployment across Douyin, TikTok, and enterprise API customers via Volcano Engine.
Yi-Lightning
Yi-Lightning is 01.AI's (ιΆδΈδΈη©) fastest and most cost-efficient model, purpose-built for high-throughput production workloads. It delivers competitive performance against GPT-4o-mini and Claude Haiku at a fraction of the cost, with exceptional bilingual Chinese-English capabilities. Yi-Lightning excels at classification, entity extraction, summarization, and high-frequency API tasks where latency and cost-per-call are critical constraints.
