Why it matters

Routing and fallback policies are quickly becoming the default way to control token burn in production: the cheapest capable model wins, and expensive calls are reserved for hard cases.

Tokenmaxxing read

Tokenmaxxing is architecture: add routing rules (by task, budget, confidence), cache shared context, and monitor per-agent cost curves so cost scales with difficulty, not with habit.

Source takeaway

The list positions routing layers as a control plane for multi-model stacks, highlighting policy-driven selection, evaluation hooks, and observability as key differentiators.

‘What we’re seeing right now is just rapid escalation in AI token spend’: Accenture tells staff to stop using AI for unnecessary tasks amid surging costs

Leaked internal audio, reported by IT Pro via 404 Media, shows Accenture telling staff to stop burning AI tokens on low-value work like turning PDFs into slide decks, as its agentic-AI lead flags a sharp jump in token spend.

AI cost challenges mount as agent use gets more complex: KPMG

KPMG’s Q2 AI Pulse (204 US leaders at $1B+ firms) finds twice as many companies now running fleets of coordinated agents — up to 18% from 9% — yet only 26% can see in real time what AI at scale actually costs them.
