Cloudflare Cut Its AI Code Reviewer's Bill 68% by Hunting Cache Writes, Not Buying Bigger Models
Cloudflare's AI review bill doubled to $2.46 with no architecture change. Agents traced the tokens, fixed cache breakpoints and re-picked models, landing at $0.77 per review.

Diagram of AI review session spend: output tokens 23% (text the model writes), cache writes 43% (context it is about to see), cache reads 34% (context already seen); connectors link the cache-write and cache-read boxes to a box reading 77% of spend equals repeated context.

Diagram of the LEASH escalation loop: a weak open-weight agent acts by default, a latent uncertainty check compares hidden states with past success and failure trajectories, escalation hands control to a strong frontier agent, and a shadow observer keeps watching after handoff, beside author-reported OSWorld results.

LEASH Escalates to Frontier Models Only on Latent Uncertainty, Matching Always-On Claude Opus 5 on OSWorld at 19.2% Lower Inference Cost

A new arXiv paper keeps a small open-weight agent in control of computer-use tasks and hands off to a frontier model only when the weak model's hidden states resemble past failures. Authors report OSWorld success matching always-on Claude Opus 5 at 19.2% lower inference cost.
