CONCEPT
ATLAS.
A navigable vocabulary for recurring ideas. Concepts are not definitions frozen in time; they are maintained as working models connected to notes, papers and experiments.
Context Engineering
Designing the information environment presented to a model at each decision point.
Agent Memory
Mechanisms and policies for persisting state that may become useful in future context.
Retrieval-Augmented Generation
Grounding generation with external evidence selected at runtime.
Attention
A mechanism for allocating representational capacity across parts of a sequence.
Inference-Time Compute
Spending additional compute during inference to search, verify or deliberate.
Tool Use
Allowing a model-driven system to invoke external functions and incorporate their results.
World Models
Internal representations that support prediction, planning and counterfactual reasoning.
Semantic Routing
Selecting models, tools or retrieval operators based on the structure of a request.
Vector Embeddings
Learned representations used for similarity, retrieval, clustering and routing.
