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.

Inflection AI

  • Inflection AIs consumer product Pi is distributed as a free app with no subscription tiers or in-app purchases named in its App Store listing

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.

Inflection AI: Is Inflection AI's Pi service free to use?

The website invites users to 'Try Pi' but does not disclose pricing details, whether there is a free tier, usage limits, or what happens after a trial period.

Source
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.

Inflection AI: Does Pi have a paid tier or premium features?

Pricing information is not published on Inflection's main website. Users must try the Pi platform or contact support to learn about premium options or costs.

Source
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.

Inflection AI: What commercial terms apply to using Pi?

Inflection does not disclose subscription models, pricing tiers, commercial licenses, or terms of service on their homepage, directing questions to support channels.
