Did your AI bill just jump overnight — even though no one announced a price increase?

In episode #369, Ben Murray breaks down the hidden AI price hike that's quietly hitting SaaS P&Ls this month. Anthropic shipped a new tokenizer underneath Claude Opus 4.7 — same menu pricing as 4.6, but real enterprise workloads are showing 12-27% higher effective cost, with some prompts consuming up to 35% more tokens for identical output. Most finance teams won't catch this variance until the invoice lands. If you're running AI in production, paying for Claude Code, or modeling AI COGS into next year's plan, this is the cost dynamic you need on your radar before the next board meeting.

• Why "same per-token pricing" doesn't mean same cost — and how a new tokenizer can quietly inflate your token consumption by 35%
• The real-world math: how a $50K/month API spend can balloon to $67K with zero changes to the pricing page
• What Anthropic's doubled Claude Code per-developer estimate ($6 → $13/day) signals about the end of subsidized AI pricing
• Why the era of "AI is just going to keep getting cheaper" assumptions is breaking down — and what that means for forecasting and runway
• The exact metrics to monitor in your Anthropic console today to catch token volume spikes before they hit your GL
• How to use the Inference Efficiency Ratio (revenue ÷ token costs in COGS) to measure AI margin if you're embedding AI into your product
• Why finance teams now need to document internal-use AI models the same way they document internal-use software

Tune in before your next Anthropic invoice lands — and learn what to track now so AI variance doesn't become a board question.
