Welcome to Yi! 😘
Yi model family is a series of language and multimodal models. It is based on 6B and 34B pretrained language models, then extended to chat models, 200K long context models, depth-upscaled models (9B), and vision-language models.
⭐️ Highlights
Strong performance: Yi-1.5-34B is on par with or surpasses GPT-3.5 in commonsense reasoning, college exams, math, coding, reading comprehension, and human preference win-rate on multiple evaluation benchmarks.
Cost-effective: For 6B, 9B, and 34B, you can perform inference on consumer-grade hardware (like the RTX 4090). Additionally, 34B is large enough with complex reasoning and emergent abilities, giving a nice performance-cost balance.
