The Free Token Lunch Is Over for Marketers
The article warns marketers that recent AI model releases and pricing changes (notably Anthropic’s Claude Sonnet 5 and pricier rivals like Fable 5) are changing the unit economics of AI. Cheaper per-token rates previously encouraged wider and deeper token use, especially with reasoning-enabled models that consume many more tokens. Firms that assumed token costs and token-per-task needs would stay flat risk higher bills. Researchers propose measuring the "cost-of-pass" (the expected cost to produce a correct result), and businesses should right-size model selection — using lightweight models for simple tasks and reserving larger/reasoning models for genuinely complex problems. Marketers should ask vendors why every task defaults to the same model and prepare their stacks for changing AI economics.
- •Anthropic released Claude Sonnet 5, prompting discussion about AI pricing and token economics.
- •Alternatives like Fable 5 are priced at roughly twice Anthropic’s prior top-tier model and are no longer treated as unlimited-plan features.
- •Ramp found average cost per million tokens has fallen over the past year, but overall AI spending continues to rise due to broader use cases and increased token consumption from reasoning-enabled models.
