Need more than your plan includes?
When you reach your plan's monthly limit you don't stop working — upgrade to a bigger plan, or buy credits and pay for usage as you go. Credits never expire and draw down only by what your tasks actually use.

Bring your own model
Prefer to run Prism on your own OpenAI-compatible endpoint? Connect it from the console and Prism calls it with your key — usage is billed by your provider, not your credits. Plan coverage doesn't extend to your own model, so license the capabilities you need à la carte, billed monthly.

FAQ
Can I change plans later?
Yes — upgrade, downgrade, or cancel anytime from your console. Switches are prorated and take effect immediately; cancelling keeps your plan through the end of the billing period.
What happens when I hit my plan's limit?
Upgrade to a bigger plan, or buy credits and keep going — credits draw down by what each task actually uses, and you can watch your balance and spend in the console.
What do I need to run it?
Siemens NX with the Prism panel installed, a Polymath account, and your own active NX license — Prism plans don't include one. Prism works against your live, open part.
Can I use my own model?
Yes — connect any OpenAI-compatible endpoint with your own API key. Your provider bills the model usage directly, and you license the capabilities you need à la carte instead of a plan.
