When dynamic pricing can double or triple a heavy user’s bill, a startup that bundles \u003Ca href=\"\u002Ftag\u002Finference\">inference\u003C\u002Fa> into its own price has a problem.\u003C\u002Fp>\u003Cp>That is especially true in vibe coding, where the user experience depends on frequent model calls.

That view is getting harder to defend. If a product depends on expensive frontier models, user-owned keys may be the only structure that keeps margins predictable.\u003C\u002Fp>\u003Cp>The deeper lesson is simple: in AI apps, control over the model bill is control over the business. If you do not own the inference cost, you do not fully own the product economics.\u003C\u002Fp>\u003Cp>For vibe coding tools, the next move is obvious. Support multiple providers, make BYOA easy, and give users clear cost visibility from day one.
