中文摘要
Databricks 把 AI coding 成本上涨拆成可治理的工程问题：追踪效率前沿、保留 harness/模型灵活性、做 request/task routing、用可见性和渐进式 spend gate 替代硬预算，并通过上下文压缩、缓存和 AI Gateway 降低 token overhead。文章给出 Smart Router 平均任务成本降低 30% 以上、harness 与缓存调优使生成 token 和成本接近减半等经验。
English Summary
Databricks frames AI coding cost growth as an engineering and governance problem. The post covers the efficiency frontier for coding models, meta-harnesses, request/task routing, progressive spend gates, context compression, prompt caching, and AI Gateway infrastructure, citing more than 30% average task-cost reduction from Smart Router and nearly 50% token/cost reduction from harness and caching tuning.
Intake Rationale
AI coding 的规模化落地开始从模型能力转向成本可见性、路由和网关治理。

Source Excerpt
Managing AI Coding Costs at Scale
AI coding tools deliver immense value: at Databricks, agentic coding has measurably improved every velocity metric we track and, in some teams, driven an order-of-magnitude gains in output. But nearly every company deploying AI tools at scale has hit the same wall: exponentially growing costs.
The post outlines proven cost management techniques: the efficiency frontier for coding models, open source and lower cost models, harness/model flexibility, dynamic request and task routing, visibility/tripwires/budgets, token overhead reduction, prompt caching, and the AI Gateway design pattern. Internal results at Databricks suggest Smart Router reduces average task cost by more than 30%; harness and caching tuning led to almost a 50% reduction in generated tokens and associated costs.
