- [Prefix Caching](https://fp8.co/glossary/prefix-caching): Prefix caching is a self-hosted inference optimization that stores KV cache states for common prompt prefixes on the serving infrastructure, enabling instant context reuse without recomputation.
- [Prompt Caching](https://fp8.co/glossary/prompt-caching): Prompt caching is an inference optimization where API providers store and reuse precomputed KV cache states for repeated prompt prefixes, reducing latency and cost for requests sharing common context.
- [Prompt Engineering](https://fp8.co/glossary/prompt-engineering): Prompt engineering is the practice of crafting and refining instructions given to language models to elicit accurate, relevant, and properly formatted outputs for specific tasks.
- [Prompt Injection](https://fp8.co/glossary/prompt-injection): Prompt injection is an attack technique where malicious instructions are embedded in user inputs or external data to override a language model's system prompt and alter its intended behavior.
- [Quantization](https://fp8.co/glossary/quantization): Quantization reduces neural network memory usage and accelerates inference by converting model weights from high-precision floating point to lower-precision integer representations.
- [ReAct Pattern](https://fp8.co/glossary/react-pattern): ReAct is an agent prompting pattern that interleaves reasoning traces with action execution, enabling language models to plan, act, and observe iteratively to solve complex tasks.
- [Red Teaming](https://fp8.co/glossary/red-teaming): Red teaming in AI involves systematically probing AI systems for vulnerabilities, biases, and failure modes by simulating adversarial attacks and edge-case scenarios.
- [Retrieval-Augmented Generation (RAG)](https://fp8.co/glossary/retrieval-augmented-generation): Retrieval-augmented generation is an architecture that enhances language model outputs by retrieving relevant documents from external knowledge sources and including them in the model's context.
- [RLHF](https://fp8.co/glossary/rlhf): RLHF (Reinforcement Learning from Human Feedback) trains AI models to align with human preferences by using human judgment as a reward signal to fine-tune model behavior.
- [Semantic Caching](https://fp8.co/glossary/semantic-caching): Semantic caching stores LLM responses indexed by the semantic meaning of queries rather than exact string matches, enabling cache hits for paraphrased questions that would miss traditional caches.
- [Serverless Computing](https://fp8.co/glossary/serverless): Serverless computing is a cloud execution model where the provider dynamically allocates resources and bills only for actual compute time used during function invocations.
- [Speculative Decoding](https://fp8.co/glossary/speculative-decoding): Speculative decoding is an inference acceleration technique that uses a smaller draft model to propose multiple tokens in parallel, then verifies them against the larger target model in a single forward pass.
- [Structured Content](https://fp8.co/glossary/structured-content): Structured content is information organized with consistent formatting, semantic markup, and machine-readable metadata that enables automated processing by search engines and AI systems.
- [Structured Output](https://fp8.co/glossary/structured-output): Structured output is a language model capability that constrains generation to produce valid JSON, XML, or other schema-conforming formats, ensuring reliable parsing by downstream systems.
- [TensorRT-LLM](https://fp8.co/glossary/tensorrt-llm): TensorRT-LLM is NVIDIA's open-source library that optimizes large language model inference through kernel fusion, quantization, and hardware-specific compilation for maximum GPU utilization.
- [Token Budget](https://fp8.co/glossary/token-budget): A token budget is the allocated limit on input and output tokens for a language model request, used to control costs, latency, and context window utilization.
- [Tool Orchestration](https://fp8.co/glossary/tool-orchestration): Tool orchestration is the coordination layer that manages how AI agents discover, select, invoke, and compose multiple tools to complete complex multi-step tasks autonomously.
- [Tool Use (Function Calling)](https://fp8.co/glossary/tool-use): Tool use is a capability that allows language models to invoke external functions, APIs, or services by generating structured calls that are executed by the host application.
- [Transformer Architecture](https://fp8.co/glossary/transformer): The transformer is a neural network architecture that uses self-attention mechanisms to process sequential data in parallel, forming the foundation of all modern large language models.
- [Vector Database](https://fp8.co/glossary/vector-database): A vector database is a specialized storage system designed to index, store, and perform fast similarity searches over high-dimensional embedding vectors at scale.
- [vLLM](https://fp8.co/glossary/vllm): vLLM is an open-source LLM serving engine that uses PagedAttention to efficiently manage GPU memory for KV caches, enabling high-throughput inference with continuous batching.
