The Inherent Bottleneck of Autoregressive Generation<\/h2>\n<p class=\"text-slate-300 leading-relaxed\">\nAutoregressive language models generate tokens sequentially. To answer a simple binary query (&#8220;Is this payment fraudulent?&#8221;), an LLM performs forward passes for every single generated token, incurring an unavoidable latency penalty of <strong>1,200ms to 4,500ms<\/strong>.\n<\/p>\n<div class=\"my-6 p-4 rounded-xl bg-slate-900 border border-slate-800\">\n<h3 class=\"font-bold text-mint text-sm mb-2\">Core Structural Disadvantages of Chat LLMs:<\/h3>\n<ul class=\"list-disc list-inside space-y-1 text-xs text-slate-300\">\n<li><strong>High P99 Latency:<\/strong> 2 to 5 seconds per request makes in-line API gating impossible.<\/li>\n<li><strong>Fragile JSON Parsing:<\/strong> Unstructured filler words occasionally break strict programmatic schemas.<\/li>\n<li><strong>Uncalibrated Probabilities:<\/strong> Softmax output distribution from general models lacks empirical Bayesian calibration.<\/li>\n<li><strong>Astronomical Token Costs:<\/strong> Re-evaluating 500-token system prompts millions of times per day inflates cloud bills.<\/li>\n<\/ul>\n<\/div>\n<h2 class=\"text-xl font-bold text-white mt-6 mb-3\">2.
