Why does the same AI task cost dramatically different amounts across providers?

Each AI vendor ships its own tokenizer — a compression dictionary that determines how text is split into billable units. The same input string can tokenize into 1 token on one model and 4 on another. Non-English text is worse. So 'price per million tokens' across vendors is not a comparable unit — it is a different measurement depending on whose tokenizer is doing the counting.

What should a finance or procurement team do before signing an enterprise AI contract?

Run your actual production prompts through each candidate model and compare output token counts — not advertised per-token prices. The billing gap between identical tasks across models can exceed 40x. Advertised rates are meaningless without knowing how each vendor's tokenizer handles your specific text.

What is the strongest argument that Microsoft's AI cost problem is overstated?

Caching and prompt optimization can substantially reduce token spend at scale, and enterprise contracts often include volume discounts not reflected in public per-token pricing. The counter-argument holds if your use case is narrow and cacheable — it fails for the open-ended agentic deployments Microsoft is actively pushing.

Microsoft's Token Cost Problem Is Already Inside the Budget Line

Internal Microsoft data on AI token costs at scale, surfaced this week, confirms what finance teams are beginning to find: the per-query math doesn't hold at production volume.

When the Unit of Cost Is Not a Unit

The 45x billing gap documented across four models running an identical prompt

is not an outlier — it is a structural feature of a market where every vendor ships its own tokenizer. Non-English text compounds the problem: Hindi and Japanese can cost two to four times more on English-heavy vocabularies

. Enterprises that built AI cost projections on 'price per million tokens' have been doing arithmetic in different currencies without knowing it. The

AI cost problem that's already past the budget line

is not a future risk; finance teams at scale are discovering it now.
