Context Management
ConceptContext management refers to the set of mechanisms and strategies for maintaining, storing, and scheduling relevant background information (context) in information processing or dialogue systems. Its core objective is to ensure that a system can access necessary historical information and state data when processing requests. Common approaches include context caching, compression and summarization, history maintenance, and lifecycle control. It is widely applied in programming language runtimes, operating systems, and AI dialogue systems.
RAG
ConceptRetrieval-Augmented Generation (RAG) is an AI technical framework that combines information retrieval with the generative capabilities of large language models. Its core mechanism involves retrieving relevant documents or passages from an external knowledge base before generating a response, and providing them as context to the model. This allows the model to draw on current or domain-specific knowledge, effectively mitigating hallucination issues and knowledge cutoff limitations inherent in large language models.

Tool Calling
ConceptTool Calling is a capability mechanism that enables large language models (LLMs) to interact with external tools or APIs. During response generation, the model can identify user intent and produce structured tool-invocation instructions; the runtime environment then executes the corresponding functions or services and returns results to the model. This enables tasks beyond pure text generation, such as information retrieval, code execution, and data manipulation, and is a foundational capability for building AI agents and complex automated workflows.
AI Safety
ConceptAI Safety is an interdisciplinary field focused on ensuring that artificial intelligence systems operate reliably according to intended objectives and do not produce harmful outcomes. Core topics include system robustness and adversarial defense, AI alignment (ensuring system behavior conforms to human intent and values), interpretability and transparency, and the prevention of long-term risks such as those associated with superintelligence. The field draws on computer science, ethics, and control theory to reduce technical and societal risks throughout the design, deployment, and use of AI systems.
