Cost:
what does AI actually cost? Model usage (tokens), computing, the software around it, people to run it and ongoing operations. The advertised token price is only part of it. Evidence: in September 2026, OpenAI priced its new lower-cost GPT-6 models at half the API price of the versions they replace, and Anthropic's Claude Opus 5.5 list prices are 20% below Opus 5 (see AI Models). FOCUS, the FinOps Foundation's standard for cost data, released version 1.4 in June 2026; version 1.5, scheduled for ratification on December 3, 2026, adds common labels for AI token billing across providers.
