Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

C3 AI Suite

  • The commercial model bundles software with heavy professional services, so the licence line in the quote understates the first-year cost by a wide margin and budgets set from the licence alone overrun.
  • Applications are written against C3 proprietary types, so nothing built on the platform ports to a generic Spark or Databricks stack without a rewrite, which makes exit expensive after two or three years.
  • Contracts have historically been large multi-year commitments with a small number of very large customers, which means pricing is negotiated case by case and small buyers get little leverage.
  • Skills are scarce outside C3 itself, so hiring an engineer who already knows the platform is hard and the customer stays dependent on the vendor for extensions.
  • Pre-built applications need substantial configuration against the customer data model before they produce anything, so the marketing claim of a packaged app understates the integration work by months.

OSIsoft PI System

  • OSIsoft is now AVEVA and osisoft.com redirects to the AVEVA PI System pages
  • No pricing is published; osisoft.com/pricing resolves to AVEVA product pages with no rate, minimum or cost driver
  • Licensing runs through the AVEVA Flex Subscription Program rather than a published per-seat or per-tag price
  • The PI System is split across separately listed products including PI Server, PI Vision, PI Data Infrastructure and Edge Data Store

Answered from the vendors’ own pages

C3 AI Suite: Does C3 publish pricing?

No. Everything is quoted, and the shape of the deal, pilot then subscription, means the first number you see is for a proof of value rather than the platform.

OSIsoft PI System: How much does the AVEVA PI System cost?

AVEVA PI System (formerly OSIsoft PI System) operates on a subscription-based commercial model with customized pricing. The company structures subscriptions to match specific use cases and business needs, requiring direct contact with account representatives.

C3 AI Suite: Can it run in a classified environment?

Yes. C3 supports air-gapped and government cloud deployments, including FedRAMP-authorised environments, which is a large part of why defence buyers choose it.

OSIsoft PI System: What is AVEVA PI System's pricing model?

C3 AI Suite: Do we own the models we build?

You own the models and the data. The application logic is written in C3 types, so the artefacts are portable in principle and impractical to move in practice.
