- Agentic Workflow
- Related: Tool Calling, Agent Guardrail
A multi-step process in which an AI agent plans, selects tools, executes actions, and evaluates results across several turns, rather than returning a single response to one prompt.
- Tool Calling
- Related: Agentic Workflow, Orchestration Layer
A mechanism that lets a language model invoke an external function, API, or data source by emitting structured arguments, with the platform executing the call and returning the result to the model.
- Orchestration Layer
- Related: Agentic Workflow, Agent Trace
The platform component that sequences agent steps, routes requests between models and tools, manages state, and enforces retries or fallbacks during a multi-step run.
- Agent Guardrail
- Related: Human in the Loop, Prompt Injection
A configured constraint that limits what an agent may do, such as blocking certain tools, capping spend, requiring approval before an action, or restricting topics the agent can address.
- Human in the Loop
- Related: Agent Guardrail, Agent Trace
A checkpoint where an agent pauses and waits for a person to approve, edit, or reject a proposed action before the workflow continues to the next step.
- Agent Trace
- Related: Orchestration Layer, LLM Observability
A recorded sequence of an agent run's steps, including model calls, tool invocations, inputs, outputs, latency, and errors, used for debugging and audit.
- Retrieval-Augmented Generation
- Related: Vector Database, Chunking, Grounding
A pattern where relevant documents are retrieved from a knowledge source and inserted into the model's context so answers are grounded in current, domain-specific content.
- Vector Database
- Related: Embedding, Retrieval-Augmented Generation
A store that indexes text or other content as numeric embeddings and returns the nearest matches to a query embedding, enabling semantic search over a knowledge base.
- Embedding
- Related: Vector Database, Semantic Similarity
A dense numeric representation of text or other content produced by a model, where items with similar meaning land close together in vector space.
- Chunking
- Related: Retrieval-Augmented Generation, Vector Database
The practice of splitting source documents into smaller passages before indexing, balancing passage size so retrieved context is specific enough yet still contains complete ideas.
- Grounding
- Related: Retrieval-Augmented Generation, Hallucination
Tying a generated answer to supplied evidence such as retrieved passages or tool outputs, so claims can be checked against sources rather than relying on model memory.
- Hallucination
- Related: Grounding, Faithfulness
A generated statement that is fluent but unsupported or factually wrong, arising when a model fills gaps from learned patterns instead of from reliable evidence.
- Prompt Injection
- Related: Agent Guardrail, Red Teaming
An attack where untrusted content, such as a retrieved page or user message, contains instructions that try to override the system prompt or redirect the model's behavior.
- Faithfulness
- Related: Grounding, Hallucination
A generation quality measure of whether every claim in an answer is supported by the provided context, as opposed to relevance, which concerns whether the answer addresses the question.
- Feature Discovery
- Related: Feature Engineering, Target Leakage
Automated profiling of a dataset that identifies candidate input variables, their types and distributions, and flags leakage or quality problems before modeling begins.
- Target Leakage
- Related: Feature Discovery, Holdout Set
A situation where an input feature contains information that would not be available at prediction time, or directly encodes the outcome, producing optimistic scores that fail in production.
- Model Blueprint
- Related: Autopilot, Leaderboard
A predefined modeling recipe that pairs a data preparation pipeline with one or more algorithms and their default settings, used as a starting point in automated model selection.
- Autopilot
- Related: Model Blueprint, Leaderboard
The automated mode that runs feature engineering, model training, and tuning across many candidate approaches, then ranks results so a user can choose a model to deploy.
- Leaderboard
- Related: Autopilot, Holdout Set
A ranked comparison of trained models scored on a chosen validation metric, letting a practitioner weigh accuracy against training time and interpretability.
- Holdout Set
- Related: Cross-Validation, Target Leakage
Data withheld from training and used once to estimate how a selected model will perform on unseen cases, guarding against overfitting to the validation data.
- Cross-Validation
- Related: Holdout Set, Leaderboard
A resampling procedure that splits training data into folds, trains on some folds and scores on the rest repeatedly, producing a more stable performance estimate.
- Feature Impact
- Related: Prediction Explanations, Feature Discovery
A model-agnostic explanation showing how much each input changes predictions on average, typically computed by perturbing a feature and measuring the shift in output.
- Prediction Explanations
- Related: Feature Impact, Model Documentation
Per-row reasons showing which input values pushed a single prediction up or down and by how much, used to justify decisions to reviewers, customers, or regulators.
- Model Registry
- Related: Model Documentation, Champion-Challenger
A catalog that tracks trained model versions, their metadata, training data lineage, and deployment status, so teams can promote, roll back, and audit models.
- Model Documentation
- Related: Model Registry, Bias Testing
A structured record describing a model's purpose, data, performance, limitations, and monitoring plan, often assembled to satisfy internal review and regulatory expectations.
- Bias Testing
- Related: Fairness Metric, Model Documentation
Evaluating model outcomes across protected or sensitive groups to detect disparate error rates or selection rates, and deciding whether mitigation or rejection is warranted.
- Fairness Metric
- Related: Bias Testing, Model Documentation
A quantitative measure of outcome parity between groups, such as equal error rates or similar selection rates; different metrics can conflict, so the choice must match the use case.
- Data Drift
- Related: Concept Drift, Drift Monitoring
A change over time in the distribution of input features compared with the training data, which can degrade predictions even when the underlying relationship is unchanged.
- Concept Drift
- Related: Data Drift, Drift Monitoring
A change in the relationship between inputs and the target, so the same input values now imply different outcomes and the model's learned mapping becomes stale.
- Drift Monitoring
- Related: Data Drift, Concept Drift
Ongoing comparison of live input and prediction distributions against a baseline, with thresholds and alerts that flag when a model needs retraining or investigation.
- Service Health Monitoring
- Related: Drift Monitoring, Champion-Challenger
Tracking operational signals of a deployed model endpoint, such as request volume, latency, error rates, and availability, to catch failures that are not statistical drift.
- Champion-Challenger
- Related: Model Registry, Service Health Monitoring
A deployment pattern where the current production model serves traffic while one or more challenger models score the same requests, so their performance can be compared safely.
- LLM Observability
- Related: Agent Trace, Faithfulness
Instrumentation of generative applications that records prompts, responses, token usage, latency, and quality scores so teams can detect regressions and control cost.
- Semantic Similarity
- Related: Embedding, Vector Database
A score expressing how close two pieces of text are in meaning, usually computed from embeddings, and used to rank retrieved passages or compare generated answers.
- Red Teaming
- Related: Prompt Injection, Agent Guardrail
Deliberate adversarial probing of a model or agent with hostile prompts and scenarios to surface unsafe behavior, data leakage, or guardrail gaps before release.
- Feature Engineering
- Related: Feature Discovery, Feature Impact
Creating or transforming input variables, such as ratios, date parts, or text encodings, to make patterns easier for a model to learn and improve predictive performance.
