Evaluate & rank

Know which model works for your product before you ship it.

Bring your own custom-trained or pre-trained models and define the scenarios your product depends on. Omega runs several models on the same scenario at once, each in an isolated sandbox, and ranks them against each other.

The problem

Picking a model shouldn't be a guess.

Benchmarks

Leaderboards aren't your use case.

A model that wins public benchmarks can still fail on the tasks your product actually runs.

Fair comparison

Comparing by hand doesn't hold up.

Testing models one at a time, on different prompts and different days, gives results you can't compare.

Updates

New versions break things quietly.

A model update can improve one scenario and make another worse without anyone noticing.

How it works

From your models to a ranking in five steps.

  1. Bring your models

    Add custom-trained, fine-tuned or pre-trained models to your workspace.

  2. Define scenarios

    Describe the use cases to test when the run starts, and what counts as a pass.

  3. Run side by side

    Every model runs on the same scenarios at the same time, each in its own sandbox.

  4. Get the ranking

    See which model wins each scenario and which wins overall.

  5. Re-test on change

    Run the same scenarios on every new version to catch regressions.

Scenarios

Scenarios written for your product.

Describe the use cases that matter when the run starts, in your own terms, with the criteria that count as a pass. Every model is judged on the same scenarios, so the results are comparable.

  • Your use cases, not a public benchmark
  • Pass criteria you define
  • The same scenarios for every model in the run

Example scenarios
Side by side

Many models, one fair test.

Run several models on the same scenario at once. Each one gets its own isolated sandbox, so no run affects another and every model sees exactly the same test.

  • Several models per scenario, at the same time
  • One isolated sandbox per model
  • Your models next to pre-trained ones

Regressions

Catch regressions before your users do.

When a model changes, run the same scenarios again. Omega compares the new results with the last run and flags any scenario that got worse, even when the overall score went up.

  • Same scenarios on every new version
  • Scenario-level comparison with the last run
  • Regressions flagged, not averaged away

Who uses it

For the teams that own model decisions.

ML and AI teams

Choose and update models with evidence.

Compare your fine-tuned models with pre-trained ones on the exact scenarios your product depends on.

Engineering leaders

Make model decisions you can explain.

Point to a ranking per scenario when you pick a model, and see straight away when an update helps or hurts.

Works with the rest of Omega

One platform, three workflows.

Deployment and data

Where your work runs.

Omega cloud
A cluster dedicated to your organisation. No organisation shares a cluster with another.
On-prem
On request, Omega runs inside your own servers.
This workflow
Every model you evaluate runs in its own isolated sandbox, inside your dedicated cluster or your own servers.
Training
Your code, models and specifications are never used to train Omega's models.
FAQ

Questions about Evaluate & rank.

What kinds of models can we evaluate?

Your own custom-trained or fine-tuned models, and any pre-trained models you want to compare them with.

Can we test several models on the same scenario?

Yes. That is what Evaluate & rank is built for: run several models on the same scenario at once, and Omega ranks them against each other.

How do we define scenarios?

You describe your use cases at the start of a run, along with what a good result looks like. Every model in the run is tested against the same scenarios.

Where do evaluation runs execute?

Each model runs in its own isolated sandbox, on your organisation's dedicated cluster, or inside your own servers if you use Omega on-prem.

How are regressions caught?

Re-run the same scenarios on each new model version. Omega compares the results with the previous run and flags any scenario that got worse.

Get started

Bring your models and one real scenario.

We'll run them side by side and show you which one wins, scenario by scenario.
