Inference performancePrefix cache
Prefix cache is the serving concept concerned with prefix cache during AI inference.
Inference performanceProcessing time
Processing time is the serving concept concerned with processing time during AI inference.
Inference performancePrompt caching
Prompt caching reuses processing associated with previously supplied prompt content, often a matching prefix, to reduce repeated input work. It differs from response caching, which returns a stored answer instead of generating a new one.
Inference performancePrompt length
Prompt length is the serving concept concerned with prompt length during AI inference.
Inference performanceQuantization
Quantization represents model values with lower numerical precision than the original model. It can reduce memory requirements and sometimes improve serving efficiency, with possible effects on output quality and supported operations.
Inference performanceQuantization aware serving
Quantization aware serving is the serving concept concerned with quantization aware serving during AI inference.
Inference performanceQueue latency
Queue latency is the serving concept concerned with queue latency during AI inference.
Inference performanceRequest coalescing
Request coalescing is the serving concept concerned with request coalescing during AI inference.
Inference performanceRequest rate
Request rate is the serving concept concerned with request rate during AI inference.
Inference performanceRequest scheduler
Request scheduler is the serving concept concerned with request scheduler during AI inference.

Response cache is the serving concept concerned with response cache during AI inference.
Inference performanceRetry amplification
Retry amplification is the serving concept concerned with retry amplification during AI inference.
Inference performanceScale to zero
Scale to zero is the serving concept concerned with scale to zero during AI inference.
Inference performanceSemantic caching
Semantic caching stores a response and retrieves it for a later request judged similar in meaning. It uses a similarity method rather than requiring the later request to match the earlier text exactly.
Inference performanceSequence packing
Sequence packing is the serving concept concerned with sequence packing during AI inference.
Inference performanceServer sent events
Server sent events is the serving concept concerned with server sent events during AI inference.
