FinOps Resources & Guides

Learn how to turn your billing data into clear, actionable answers — using Training Objects and conversational insights that actually explain what changed and what to do next.

FinOps for AI

AI spend patterns that standard FinOps tools miss — cross-service billing disguises, OCU floor costs, inference waste, and detection logic for the new AI infrastructure stack.

Amazon Bedrock Knowledge Base Costs Don't Show Up Under Bedrock
When you create a Bedrock Knowledge Base, AWS silently provisions OpenSearch Serverless at $345/month — under the wrong service name. Five real incidents, detection SQL, and a fix checklist for builders, FinOps practitioners, and engineering leaders.

Runaway AI Inference: How a Prompt Loop at 2 AM Becomes a $4,200 Weekend Bill
Token consumption can spike 18× above your rolling baseline in 48 hours. Standard FinOps alerts won't catch it. Six real incidents ($15 to $50K), the FOCUS-native detection SQL, and a three-layer fix for the engineer who built it, the analyst who watches the bill, and the manager who owns the outcome.

SageMaker Real-Time Inference Endpoints Bill When Nobody Is Calling Them
SageMaker real-time endpoints can't scale to zero — they bill $724+/month whether they receive 0 requests or 10,000. The charge is invisible in standard billing data until you join it with CloudWatch. Five real incidents, detection SQL, and a fix checklist for builders, FinOps practitioners, and engineering leaders.

A Stolen API Key, 48 Hours, $82,000: The AI Billing Signature That Standard FinOps Tools Miss
A Google Maps key gained Gemini scope without the owner knowing. 48 hours, $82,314. 2,863 live exposed keys in Common Crawl. AWS Bedrock API keys carry identical risk. The FOCUS-native detection query, why Cost Anomaly Detection can't catch this, and a full incident response checklist.

Your AI Inference Bill Grows Every Sprint Without New Traffic — It's Your System Prompts
Input token consumption climbs 15%+ month over month as developers add few-shot examples, safety rules, and RAG context across sprints — invisible to dashboards watching total Bedrock spend. Four real incidents ($800 to $8,400/month), the FOCUS-native detection query, and a fix checklist for builders, practitioners, and engineering leaders.
