Groq LPU v3: deterministic token-stream latency — the property real-time voice and agent loops actually need

Groq LPU inference engine v3 positions deterministic token-stream latency as the headline product property: predictable per-token time-to-next-token, regardless of batch size. Other inference vendors can offer low average latency, but Groq's pitch is determinism — the latency stays the same whether the system is idle or saturated. That property matters specifically for real-time voice agents (token-stream is the user's experience) and tight agent loops (latency variance compounds across steps). The pitch is 'pick the latency you want, get it always', not 'lowest possible latency, sometimes'.
