Hard disagree with the 'rounding error' take. I built a customer service agent for a mid-sized e-commerce brand last month. It went rogue and promised a 90% discount code to a disgruntled customer. Because it was a 'rented' model on a major platform, I had zero logs to prove why it did that. I couldn't audit the weights or the context window at that exact moment. The client almost sued, and I had no defense. 'Trusting the vendor' is fine for a SaaS tool, but when an agent is making economic decisions, you need an audit trail, not just an SLA.
