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.

Resemble AI

  • The Team plan jumps to $350/month for just 5 seats, a steep increase from the free Flex tier.
  • Detection accuracy rates (99.5% audio, 98% video, 96% image) mean some deepfakes can still go undetected.
  • SSO and org-wide security features are only available starting on the $1,000/month Business plan.
  • Voice cloning of another person's voice requires explicit consent verification, adding friction to some workflows.

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.

Resemble AI: What does Resemble AI cost?

Resemble AI offers a free Flex pay-as-you-go plan, a Team plan at $350/month, a Business plan at $1,000/month, and custom Enterprise pricing, with lower monthly rates available on annual billing.

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.

Resemble AI: Is there a free plan, and what are its limits?

The Flex plan is free with 1 team seat, no credit card required, and pay-as-you-go usage where purchased credits never expire.

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.

Resemble AI: How is usage metered?

Usage is billed per second or per image processed for detection (e.g. $0.035/sec for audio detection on Flex, dropping to $0.015/sec on Team and Business), with separate rates for video and intelligence analysis.
