SUMMARY

The text discusses advancements in alignment techniques for open-source large language models (LLMs) to improve complex reasoning tasks. It introduces EUS models fine-tuned from Mistol 7B and Code LLM70B, which excel in reasoning tasks. The ULTRAINTRAC dataset enhances these models' reasoning skills through diverse instructions and preference learning techniques.
