ChatGPT-5 #48
Series “Laboratory”
Introduction
Welcome back to Laboratory, the weekly dispatch where we crack open the latest breakthroughs and check if the gears are really turning—or just polished for show. This week our lens zeroes in on GPT-5, OpenAI’s long-teased update that promises faster reasoning, cleaner answers, and a smoother ride for everyday users. But behind the hype, the leap feels more like a careful stride than a moonshot toward AGI.
In this briefing, we’ll probe:
The Seamless Switch — How GPT-5 quietly retires the old model split, routing your query to the right brain—fast or slow—without you lifting a finger.
Hallucination Control — Why trimming false facts isn’t just cosmetic, but a foundational safety move for AI agents that will soon touch critical systems.
Benchmarks at the Ceiling — The uncomfortable truth: GPT-5 is acing tests that may no longer measure true intelligence, and what that means for the AGI race.
Buckle up as we sift the signal from the sales pitch—showing builders, operators, and investors where GPT-5 genuinely raises the floor, and where the ceiling hasn’t moved much at all.
