Jerry Murdock explains why token commoditization is a myth: model customization changes what a token produces, and therefore changes its value, pointing to companies like Fireworks as evidence.
“I disagree with a token is a token. that may be true at the moment with pretty much Frontier models, but I disagree with it because companies like Fireworks and others are helping companies to customize. The more you customize the model, the more the token changes its value, right? Because the more you customize what's being produced.”Jerry Murdock · 22 Aug 2026
