AI Agent
An AI system that selects and executes actions over multiple steps to pursue a goal.
AI Memory
Stored conversation state, preferences and task records, distinguished from context windows and model training, with examples of freshness and access boundaries.
Attention
A mechanism that lets a neural network weigh the relevance of different positions when computing a representation.
Claude
A family of general-purpose AI models and conversational products developed by Anthropic.
Context Window
The amount of tokenized input and generated text a model can consider within one inference context.
GPT
Generative Pre-trained Transformer, a family of autoregressive language models associated with OpenAI.
GPT-6 Astra
An OpenAI GPT-family model described for complex reasoning, coding, research and tool-based work, with a practical framework for task-level evaluation.
Gemini
A family of multimodal AI models and products developed by Google.
Hallucination in AI
A generated statement that is unsupported, fabricated, or inconsistent with the available evidence or context.
Inference
The process of running a trained model on new input to produce predictions, embeddings, or generated output.
KV Cache
A cache of attention keys and values used to avoid recomputing earlier context during autoregressive generation.
Quantization
A technique that represents model weights or activations with lower numerical precision to reduce resource use.
Retrieval-Augmented Generation (RAG)
A method that retrieves external information and supplies it to a generative model as context.
Tokenization
The process of converting text or other input into discrete units that a model can process.
Transformer
A neural network architecture that processes sequences primarily through attention mechanisms.
