We're going to need default hard budget caps on pretty much everything
One misconfigured API key and your entire cloud bill disappears into an agent's loop. Simon Willison explains why default hard budget caps aren't optional anymore.

Why it matters
As agentic AI moves into production, uncontrolled spending—from runaway agent loops, misconfigured integrations, and permission creep—is becoming a reliability and financial control crisis. Default hard caps on compute, API calls, and spend are now operational necessity, not nice-to-have governance.
The key facts
6 to knowAuthor: Simon Willison, prominent AI practitioner and Datasette creator
Focus: production agent cost control and safety
Problem domain: autonomous agent loops consuming unbounded resources without human intervention
Relevance to enterprise deployment: budget caps as a production reliability requirement, not cost optimization
Operational context: agentic systems in the wild now require hard financial guardrails similar to security permissions
Inference: this reflects real production incidents and deployment friction, not theoretical risk
