Metered cloud agent services

Krazimo vs Amazon Bedrock

On platform fee alone, Bedrock is cheaper than we are. We are going to show you the arithmetic, and then make the argument that survives it.

We concede the price

Metered per call, the hyperscaler path costs less than our plan at both of our volumes.

Retrieval that cannot fabricate

A grounding score grades an answer already written. Ours could not have written it.

One version, not seven services

Library, policy, suite and model pinned together and restorable.

The loop is free, and that is not a trick

Amazon does not charge for agent orchestration. Its AgentCore pricing page meters Runtime, Gateway, Memory, Browser, Code Interpreter, Policy, Identity and Evaluations — there is no line item for the loop, because there is no charge for it. Microsoft says the same thing in a sentence: There is no additional charge for creating or running Foundry-native agents using prompts and workflows.1 Any comparison page that prices the hyperscaler path as a stack of subscriptions is wrong, and we are not going to run one.

What you pay for instead is every call

The meter moves to the parts that do work. Retrieval is $1.00 per 1,000 Retrieve API calls2, or $4.00 per 1,000 Agentic Retrieve calls, plus $1.00 per 1,000 underlying Retrieve calls3 for the agentic variety. Guardrails are $0.104 for contextual grounding and $0.155 for content filters and denied topics. Gateway invocations are $0.005 per 1,000 Gateway API invocations6, runtime is $0.0895 per vCPU-hour7 plus $0.00945 per GB-hour8, and the index itself is $5.00 per GB of raw data, per month9.

Which comes out cheaper than us, and we would rather say so

Work those rates against a real workload and the platform fee lands well under our plan at both the volumes we publish. We could bury that. Instead: it is below, with the assumptions written out so you can change them. A comparison you can falsify in a spreadsheet is the only kind worth publishing, and a vendor that hides an unfavourable number has told you what its evidence trail is worth.

The argument that survives it

You can buy a score that grades an answer after the model has written it — that is what contextual grounding at $0.104 is, and the documentation is clear that the check runs on the output. You cannot buy retrieval that had no way to write it. Ours walks an index and opens the page it names; a path no listing offered is refused by the tool itself, before any text exists to be graded. The second thing you cannot assemble from a rate card is one version number over the library, the policy, the evaluation suite and the model, recorded with who published it and restorable. Seven metered services produce seven bills and seven change histories, and no sentence a compliance owner can sign.

The arithmetic

Worked, at 5,000 runs a month

One agentic retrieval per run, guards on the question and the answer at four text units per run, three gateway invocations, fifteen seconds of one vCPU with two gigabytes of memory, and a two-gigabyte index. Model tokens excluded on both sides, because both bill them separately.

Index storage — 2 GB

At 40,000 runs the same assumptions give roughly $253 against our $499. Change the assumptions and the numbers move — that is the point of writing them down. What does not move is that the metered path is cheaper on platform fee at both volumes, and that neither figure includes the engineering time to assemble and keep it running.

Depending on who is asking
Platform engineering

“We already have the AWS account.”

Then the metered path is genuinely cheaper and you should price it. What you are buying here is the assembly and the record, not the compute.

Compliance

“What was serving in March?”

One version pins the documents, the policy, the suite that passed and the model, with the publisher recorded. Restorable, not reconstructed from seven change logs.

Finance

“Which bill is more forecastable?”

Ours is flat and theirs tracks traffic. Below your volume that favours them; a spike is where a per-call meter is felt, and it is felt on the month it happens.

What Amazon Bedrock AgentCore publishes

Where the meter sits

The same turn, billed two ways. Every step happens either way — the difference is whether each one carries its own charge, or the turn does.

How Krazimo Studio is built

Our own architecture, stated as such. Whether it is better than the alternative is your call to make; these are the facts you would be deciding on.

  • Retrieval navigates a named index — no embedding step, and no vector store to run or re-index
  • A path no listing offered is refused by the tool itself, before any text is generated
  • Guards are deterministic rules on the finished answer, each reported by name with its reason
  • One version pins the library, the policy, the evaluation suite and the model, and can be restored
  • Usage is returned on the call that incurred it — the same number that bills
  • Unlimited agents on every plan, and no share of your model spend
Questions we get

Are you really saying a competitor is cheaper?

On platform fee, at these volumes, yes. It is checkable from published rate cards in about ten minutes, so the only thing we would gain by omitting it is the reader's trust, briefly.

Then what am I paying you for?

Retrieval that could not have fabricated the answer, guards that are rules rather than scores, and one signable version over the library, policy, suite and model. If you do not need an evidence trail, the metered path is a reasonable choice and we would rather you priced it properly.

Does the loop really cost nothing there?

Yes. AgentCore's pricing page has no line item for orchestration, and Microsoft states it outright for their equivalent. It is a real advantage of building on a hyperscaler and it would be silly to pretend otherwise.

What about the engineering time?

Not in either number above. Assembling retrieval, guardrails, evaluation and an audit trail across several metered services is real work with real ongoing cost, but it is your estimate to make, not ours to assert.
