FAQ

Multi-model AI FAQ

What is multi-model AI?

Using more than one AI model family in a workflow—often in one product—so you can match models to tasks.

Is multi-model always better?

No. If one provider covers all your work and you value its native features, single-model can be simpler.

Is an API router the same as multi-model chat?

Not quite. Routers expose models; a multi-model chat workspace adds UI, modes, and workflow tools.

How much does milkyway.chat cost?

Pro is $14.99 per month and includes all premium models plus voice chat. Lifetime is $149.99 as a one-time payment and lets you bring your own API keys. Visit the pricing page for current plan details.

Can I try the workspace before subscribing?

Yes. You can explore the interactive math visualization example without a subscription. After signing in, you can browse the workspace interface, but sending messages requires an active Pro or Lifetime plan.
