The short version

  • Only Chatbase has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Chatbase enterprise plan requires custom pricing with sales contact

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.

Chatbase

  • Enterprise plan requires custom pricing with sales contact
  • Message credits are consumption-based; exceeding monthly allocation requires additional purchase

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.

Chatbase: Is there a free tier for Chatbase?

Yes, Chatbase offers a free plan with 50 message credits per month, 1 team member, and limited access to AI models. Agents created on the free plan automatically delete after 14 days of inactivity.

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.

Chatbase: What are the differences between Standard and Pro plans?

Standard ($150/month) includes 4,000 message credits and 3 team members with voice, telephony, and API access. Pro ($500/month) includes 15,000 message credits, 5 team members, and advanced analytics with ticket support.

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.

Chatbase: How much does it cost to add extra team members beyond the plan limit?

Chatbase's pricing page does not specify the cost for adding extra team members beyond the included count in each plan. Contact sales for custom member add-on pricing.

Source
Chatbase: Do annual plans offer a discount?

Yes, yearly plans save 20% compared to monthly billing across all tiers.
