LLM infrastructure and economics for 2026: compute costs, model revocability, hallucination benchmarking, multi-provider fallback, and browser-native MCP. By Indra Gusti Prasetya.
When a model vendor shuts down, every app hard-coded to that endpoint breaks. These articles cover the infrastructure decisions that keep AI systems running across the full model lifecycle, from procurement economics and fallback routing to hallucination benchmarking and the emerging browser-native MCP layer.
GPT-5.5 scored 57% on knowledge benchmarks and 86% hallucination rate in the same run. Here is what that number actually counts.
