A working LLMOps lifecycle must carry versions, evaluation evidence, approvals, promotion state, monitoring findings, and rollback lineage through one connected path.

We build a working lifecycle for models, prompts, data, evaluations, deployments, monitoring, approvals, and lineage. Your team can see which version moved, what evidence supported it, who approved it, and how it behaves in operation. One representative change travels the tested lifecycle slice end to end, from versioned artifact to monitored deployment, with the evidence that approved each move attached to it.

We prove one complete lifecycle slice before expanding the platform, giving each integration a clear purpose and owner.

Map the lifecycle
We trace how models, prompts, data, evaluations, deployments, monitoring events, approvals, and lineage move through the current systems. Your platform owner confirms the first lifecycle slice and its acceptance path.
Build the thin slice
We implement the smallest useful path from versioned artifact through evaluation gate and environment promotion, using the systems that already fit. Engineering confirms one representative change moves through with evidence attached.
Integrate operating controls
We connect identities, approvals, exceptions, monitoring, rollback, and lineage so the platform records both normal flow and blocked changes. Your platform owner confirms consequential decisions stay in human hands.
Test and hand over
We run representative and adverse cases to check promotion, rollback, dependencies, and the operating handoff. Your platform owner accepts the tested behavior before handoff.

The output is a tested lifecycle slice plus the architecture, evidence, exceptions, and ownership needed to operate and extend it.

Experiments can reach production, but their versions, evidence, approvals, and operating history do not travel together yet.

A good fit when

Model, prompt, data, and evaluation versions sit in separate systems, so nobody can reconstruct the exact configuration that reached production.
Promotion depends on manual coordination, yet the approval evidence and lineage trail do not travel with the version moving between environments.
Monitoring shows a production problem, but the finding cannot be linked back to the evaluation evidence and configuration behind that deployment.
Version records exist across several tools, but model, prompt, data, deployment, and monitoring workflows do not share one lineage path.
The lifecycle architecture names environments and identities, yet system dependencies and blocked exception paths remain implicit.
A representative artifact can be versioned, but evaluation gates, promotion, and rollback controls are not connected in one working slice.
Acceptance tests run, yet the operating owner lacks documentation that ties behavior to named responsibilities.

Better handled as other work when

You want every engineering tool replaced even though a smaller integration can carry versioning, evidence, and approvals through the lifecycle.
Platform automation should approve production risk or policy exceptions. Those consequential decisions remain with the people named in the operating model.
You need unrelated model or application features built alongside the lifecycle slice. Those product changes require their own scope.

It's hard to test a system well if you've never had to keep one running. We operate production AI ourselves, so our evaluation, security testing, and LLMOps work starts from what actually breaks. The people on it are senior engineers, and Zeo has been doing client work since 2011.

Point us to one representative model or prompt change and the systems it touches. We will define the thinnest working lifecycle slice.

Talk to Zeo

What inputs and access do you need?

We need to see the current model, prompt, data, evaluation, deployment, monitoring, approval, and lineage workflows, along with the systems and environments behind them, representative examples, access constraints, operating owners, and the authority who can accept the first lifecycle slice.

Do you replace our existing MLOps or engineering stack?

Not by default. We first map the lifecycle job each existing system already performs. We integrate or extend the current stack where it can support versioning, evidence, approvals, promotion, monitoring, and lineage. A replacement belongs in scope only when the existing path cannot meet the agreed need.

How do you test the platform before handoff?

We run a representative change through versioning, evaluation, approval, promotion, monitoring, and rollback. We also test missing evidence, blocked approvals, failed promotion, and exception paths. The platform owner accepts the behavior and operating responsibilities for the agreed slice.

Does the platform automate release decisions?

It can automate checks, evidence collection, routing, and bounded workflow steps. Approval of production risk, policy exceptions, permissions, and release stays with the people your operating model puts in charge.
