Store Production Prompts in Your Application Code
OpenAI's deprecation of its Prompts API—with fourteen words of migration guidance—forces a question most production teams are poorly equipped to answer: where do prompts live, and who owns their history? The directive to version them in application code is correct; the problem is that most organisations lack the evaluation discipline and audit infrastructure to comply without embedding new technical debt in the same location as the old.

The Bill That Ended the Pilot
Uber burned its entire annual AI coding budget in four months — the full allocation gone by spring, no controlled overrun flagged in planning. Three-quarters of enterprises watched AI costs blow past budget last year, and the correction now arriving is triage, not enthusiasm. The governance failure and the cost failure are the same failure: if you cannot name who changed the production prompt, what it scored before it shipped, or what spending ceiling it is running under, the debt is already due.

40% Escalated to the Board: The AI Invoice Surprise of 2026
Uber burned its entire 2026 AI coding budget by April, and it is not an outlier: unexpected AI costs changed a business decision at 62% of organisations this year. A charge only reaches directors once it has cleared the spending authority of whoever caused it. Budgets set in 2025, before agentic workloads ran at production scale, are now carrying orphaned agents that burn tokens with no owner and no attributed business outcome.

The $500 Million Bill Nobody Anticipated: When AI Slop Debt Becomes a Balance-Sheet Problem
An enterprise client burned $500 million on AI services in a single month, a consequence of deferred governance rather than reckless strategy. AI slop debt, the compounding cost of zombie agents, ungoverned prompts, and abandoned POCs that still bill, has crossed from engineering irritation to balance-sheet liability. When 73% of AI initiatives exceed budget, the board question is no longer which use cases to fund but who can turn off what is already running.

Uber Burned Its Entire 2026 AI Budget in Four Months · The Bill Coming Due
Uber exhausted its entire 2026 AI coding budget by April, four months into the year. Beneath that headline sits a three-layer debt stack: technical debt, ungoverned prompt sprawl, and cost overhang accrued during a subsidised-inference era now ending. Organisations that treat AI spend as an architectural concern from day one will survive what follows; those that audit costs only after the invoice arrives will not.
