Forget brute-force scaling: the secret to better educational AI agents lies in carefully structuring their roles, skills, and tools.
LLMs can gain 40% in knowledge transfer efficiency by mining skills from open-source agent repositories, without needing retraining.
This research first reviewed and synthesized the core technologies of representative open-source LLMs, and designed an advanced 1.5B-parameter LLM tailored for the Chinese education field.
LLMs can now remember the past: Echo surpasses existing models in episodic memory tasks by incorporating temporal information into training data generation and model architecture.
