The short version

  • Only Lambda (AWS Serverless) has a free tier, so it costs nothing to try first.
  • Each has a real cost: Lambda (AWS Serverless) billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does; 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.
  • They diverge on capability: Lambda (AWS Serverless) covers Function-as-a-Service, C3 AI Suite covers Type system.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Lambda (AWS Serverless)

  • Billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does
  • Provisioned concurrency, used to avoid cold starts, is charged separately at $0.0000041667 per GB-second whether or not the function runs
  • Ephemeral storage beyond the included 512 MB is metered
  • Lambda@Edge costs $0.60 per million requests, three times the standard request rate
  • VPC use and cross-region data transfer carry EC2 charges on top

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.

Answered from the vendors’ own pages

Lambda (AWS Serverless): Is there a free tier for AWS Lambda?

Yes. AWS Lambda offers a free tier including 1 million requests per month, 400,000 GB-seconds per month, and 100 GB monthly response streaming.

Source
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.

Lambda (AWS Serverless): How is AWS Lambda charged?

Lambda charges $0.20 per million requests. Duration charges are $0.0000166667 per GB-second for x86 (up to 6 billion GB-seconds/month in US East Ohio with tiered pricing). Ephemeral storage over the included 512 MB costs $0.0000000309 per GB-second. Provisioned Concurrency costs $0.0000041667 per GB-second with a 5-minute minimum.

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.

Lambda (AWS Serverless): What are Lambda Durable Functions pricing?

Lambda Durable Functions include operations at $8.00 per million (start execution, steps, waits). Data written costs $0.25 per GB. Data retention is $0.15 per GB-month with configurable 1-90 day retention (default 14 days).

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.
