Eurus: A suite of open-source LLMs optimized for reasoning

Introduction • Evaluation

Introduction#

Eurux-8x22B-NCA is SFT and NCA fine-tuned from Mixtral-8x22B on all multi-turn trajectory pairs in UltraInteract and all pairs in UltraFeedback.

It achieves superb reasoning performance as well as exellent chat & instruction-following capabilities.

Evaluation#

We conducted overall coding, math, reasoning, knowledge, instruction-following and chat benchmarking. Results are shown below, with the best scores in open-source models bolded:
