1. Databricks cuts AI coding spend 70% — the playbook for taming agentic-coding costs
Databricks, together with Stripe, Coinbase, Uber and Ramp, shares proven techniques for scaling agentic coding without runaway costs: the biggest lever is routing coding traffic to cheaper models on the "efficiency frontier", plus gateway-level traffic shaping and end-client harness changes to hold per-user spend inside a fixed envelope. They cut AI coding spend 70% internally and open-sourced the Omnigent meta-harness and Unity AI Gateway. Unlike single-agent workflow design, this layer is about cost governance and traffic routing across many teams, models and tools.
