AI Context Management PHP 8.0+
The practice of selecting, ordering, and trimming what goes into an LLM's context window to maximise relevance while staying under token limits.

AI Fallback Routing 🧠 4
Automatically routing LLM requests to alternative models or providers when the primary fails, times out, or returns unusable output.

AI Model Selection Criteria
The systematic factors engineers weigh when choosing an LLM for a task: capability, cost, latency, context window, modality, hosting, and licensing.

AI Prompt Versioning
The practice of treating prompts as versioned artifacts — tracking changes, correlating outputs to prompt revisions, and enabling rollback when quality regresses.

AI Synthetic Data Generation
Using generative models to produce artificial training, testing, or augmentation data that mimics the statistical properties of real datasets without exposing originals.

Prompt Caching
API feature where a static prompt prefix (system instructions, large context) is cached server-side, dramatically reducing cost and latency on repeated calls that share the prefix.

Reasoning Models & Test-Time Compute
A class of LLMs trained to allocate extra inference-time compute to internal reasoning before answering, achieving large gains on math, code, and logic at the cost of latency and tokens.

Diagram: AI Guardrails AI Guardrails 🧠 4
Runtime constraints and safety filters applied around LLM calls to detect, block, or rewrite inputs and outputs that are harmful, off-topic, or policy-violating.

Diagram: AI Observability AI Observability 🧠 1
The practice of monitoring, tracing, and evaluating LLM-powered systems in production — covering latency, token costs, prompt drift, output quality, and failure modes.

Diagram: LLM Temperature & Sampling Strategies LLM Temperature & Sampling Strategies
Parameters that control the randomness and diversity of LLM output — temperature scales token probabilities, while top-p and top-k limit the candidate pool before sampling.

Diagram: Multimodal AI Multimodal AI
AI models that process and generate across multiple input or output modalities — text, images, audio, and video — within a single unified architecture.

LLM Hallucination 🧠 6
When a large language model generates confident-sounding text that is factually incorrect, fabricated, or unsupported by any source — a fundamental property of how language models work.

LLM Streaming Responses PHP 8.0+ 🧠 1
Receiving LLM output token-by-token as it is generated rather than waiting for the full response — dramatically improving perceived latency for users and enabling real-time displays of AI-generated content.

RAG — Retrieval-Augmented Generation 🧠 1
An LLM architecture that fetches relevant documents from an external knowledge base before generating a response, grounding answers in retrieved facts rather than training data alone.

Semantic Search
Search that matches by meaning and intent rather than exact keywords — a query for 'how to prevent database attacks' finds SQL injection documentation even if those exact words never appear.

Structured Output from LLMs (JSON Mode) PHP 8.0+
Instructing an LLM to return valid JSON rather than prose — either via a system prompt schema, a JSON mode API flag, or a tool-use response format — so the output can be reliably parsed and used programmatically.

Tokenization in LLMs 🧠 3
The process of splitting text into tokens — subword units that LLMs process — which directly determines context window usage, cost, and model behaviour on non-English and code inputs.

Vector Database
A database optimised for storing and querying high-dimensional vector embeddings, enabling similarity search — finding items semantically close to a query rather than exact-match lookups.

AI API Cost Management 🧠 1
Strategies to reduce LLM API costs — caching identical prompts, batching requests, choosing smaller models for simpler tasks, and minimising context length.
3mo ago AI / ML intermediate
AI-Assisted Code Generation 🧠 6
Using LLMs to generate, complete, or refactor code — powerful for boilerplate and exploration but requiring review for correctness, security, and licence compliance.
