Azure platform
(K00)
- Azure OpenAI Service — OpenAI models inside Azure's compliance/network/identity boundary; you call a deployment, not a model name.
- Deployment — a named instance of a model+version+SKU you create and call (e.g.
gpt-4o-prod). - Azure AI Foundry / Microsoft Foundry — Azure's unified build/eval/deploy/govern platform (2026 rebrand: "Microsoft Foundry"); includes the model catalog and Foundry Agent Service.
- Foundry Agent Service — managed runtime for production agents, built on the OpenAI Responses API; built-in tools, memory, observability.
- Azure AI services — the family of prebuilt AI APIs (formerly Cognitive Services).
- TPM / RPM — tokens-/requests-per-minute quota for a Standard deployment; exceeding → HTTP 429.
- PTU (Provisioned Throughput Unit) — reserved capacity for predictable latency/throughput, billed monthly.
- PAYG (Standard) — pay-per-token, shared capacity, variable latency.
- Entra ID — Microsoft's identity provider (formerly Azure AD).
- Managed Identity — an auto-managed Entra identity for a resource → keyless auth.
- RBAC — role-based access control; least-privilege roles on resources.
- Key Vault — managed secret store.
- Private Endpoint — gives a PaaS resource a private VNet IP (no public internet).
- APIM (API Management) — auth/throttle/audit gateway in front of services.
- Content Safety — harm-category filters + Prompt Shields + Groundedness detection.
- Region / Data Zone — geographic placement controlling data residency.
GenAI / LLM
(K01)
- Token — sub-word unit of text (~4 chars EN; ~2× more for Arabic); the unit of cost/latency/context.
- Embedding — a vector capturing text meaning; similar texts have high cosine similarity.
- Context window — max tokens (prompt+output) the model attends to at once.
- Autoregression — generating one token at a time, each conditioned on all prior.
- Prefill / decode — process the prompt (parallel) / emit tokens (sequential, slow).
- Temperature — sampling randomness; ~0 = deterministic (the banking default).
- Function / tool calling — the model requests your code run a function; you execute and feed back.
- Structured output — constraining the model to JSON matching a schema.
- Hallucination — a confident, unsupported (possibly false) statement.
- Fine-tuning — baking style/format into weights (not for changing facts → use RAG).
- RLHF / DPO — preference alignment training stages.
RAG & retrieval
(K02)
- RAG — Retrieval-Augmented Generation: retrieve text at query time, generate grounded answer.
- Azure AI Search — the retrieval engine (formerly Cognitive Search): keyword + vector + hybrid + semantic.
- Chunking — splitting docs into passages (~300–800 tokens, with overlap).
- BM25 — keyword ranking (term frequency × inverse document frequency).
- Vector / ANN / HNSW — semantic search via approximate nearest-neighbor graph.
- Hybrid search — BM25 + vector combined.
- RRF (Reciprocal Rank Fusion) — rank-based fusion of result lists (
Σ 1/(k+rank)). - Semantic ranker — a cross-encoder that re-scores top candidates (retrieve-then-rerank).
- Integrated vectorization — Azure indexer + embedding skill that chunks/embeds for you.
- Security trimming — filtering retrieval by the user's access groups (ACLs).
- Groundedness / faithfulness — every claim supported by retrieved context (the headline RAG metric).
Agents
(K03)
- Agent — an LLM in a loop that calls tools, observes, and decides next steps.
- ReAct — reason + act interleaving (think → tool → observe → repeat).
- LangGraph — stateful graph agent framework (nodes, edges, state, checkpointer, interrupts).
- LangChain — the building-block toolkit LangGraph is built on.
- Checkpointer — persists agent state per node → durable, resumable, auditable.
- Interrupt / human-in-the-loop — pause before a node (e.g. approval), resume later.
- Semantic Kernel — Microsoft's kernel+plugins SDK (now folded into Agent Framework).
- AutoGen — Microsoft's multi-agent framework (predecessor to Agent Framework).
- Microsoft Agent Framework — 2025 convergence of Semantic Kernel + AutoGen; Foundry-native.
- MCP (Model Context Protocol) — open client–server protocol exposing tools/resources/prompts to any host.
- Supervisor / multi-agent — specialized agents coordinated by an orchestrator.
- Orkes — Conductor-based durable workflow/agent orchestration tool.
Documents & vision
- Document Intelligence — Azure IDP service (formerly Form Recognizer): OCR + layout + extraction.
- OCR / Read — pixels → text + bounding boxes.
- Layout — text + tables + selection marks + structure (great for RAG chunking).
- Prebuilt / custom / composed model — ready-made vs trained vs auto-routed extractors.
- Confidence / STP — per-field score; straight-through-processing rate (auto-accepted %).
- Bounding region — where a field sits on the page (for highlight/audit).
- Azure AI Vision — image analysis + Read OCR + Florence models.
- OpenCV — classic CV library (deskew, threshold, contours, perspective).
- YOLO — real-time object detection (single forward pass + NMS).
- Multimodal — model accepting image + text together (GPT-4o vision).
- RTL / bidi — right-to-left / bidirectional text (Arabic rendering).
- Eastern Arabic numerals — ٠١٢٣…; normalize to Western before math.
- MSA vs dialect — Modern Standard vs spoken Gulf/etc. Arabic.
Production & data
(K07)
- FastAPI — async Python web framework (SSE streaming, Pydantic, OpenAPI).
- Pydantic — typed validation at the API boundary and for LLM output.
- SSE — Server-Sent Events; token-by-token streaming.
- Docker / ACR — container image / Azure Container Registry.
- Container Apps (ACA) / AKS / ACI — serverless containers / Kubernetes / single-container.
- Cosmos DB — globally-distributed NoSQL (Document) DB with vector search.
- Partition key — shards a container; choose high-cardinality, even-access (e.g.
conversationId). - RU/s (Request Units) — Cosmos throughput/cost currency; exceed → 429.
- Consistency levels — Strong → Bounded → Session (default) → Consistent Prefix → Eventual.
- CI/CD — automated build/test/deploy; here with an eval gate.
- Bicep / IaC — infrastructure as code.
- OIDC — federated CI auth to Azure without stored secrets.
- SQL — relational query language (SELECT/JOIN/GROUP BY); see Lab 08.
- Idempotency key — makes a retried mutating request safe (no double-execute).
Evaluation & safety
(K08)
- RAGAS — open-source RAG evaluation (faithfulness, relevancy, context precision/recall).
- Foundry evaluators — Azure-native evaluators (groundedness/safety/agent), offline + continuous.
- LLM-as-judge — a strong model scoring outputs against criteria (calibrate vs human labels).
- Recall@k / context precision — retrieval quality metrics.
- Prompt Shields — Content Safety detection of jailbreak + indirect injection.
- PII redaction — removing personal data (Presidio / Azure AI Language) before model/logging.
- Prompt injection — hijacking the model via instructions in user input (direct) or documents (indirect).
- Red-teaming — adversarial testing (e.g. Microsoft PyRIT).
- Eval gate — CI step that fails the build on a quality/safety regression.
- Observability / tracing — App Insights / Azure Monitor spans across prompt→retrieval→tool→model.
