# Evaluations

The Stratix Premium Evaluations surface — create, run, browse, and compare private evaluations.

{% hint style="info" %}
**Available in Stratix Premium.** This surface is part of the logged-in workspace at [stratix.layerlens.ai](https://stratix.layerlens.ai). Stratix Public users can browse the catalog but cannot use this feature.
{% endhint %}

The Evaluations page is where you run, browse, and compare private evaluation runs. It's the most-used surface in Premium.

URL: [`stratix.layerlens.ai/dashboard/evaluations`](https://stratix.layerlens.ai/dashboard/evaluations)

## What you can do

* **Create a new evaluation** — pick a model, dataset, and scoring config
* **Browse past runs** — filter by model, benchmark, scorer, judge, date
* **Re-run** an evaluation as configuration changes
* **Compare** two or more runs side-by-side
* **Drill into a single run** — per-row results, score distribution, latency, cost
* **Export** results to CSV/JSON for downstream analysis

## Creating an evaluation

The new-evaluation flow has 5 steps:

1. **Pick model(s)** — one or more models, including your BYOK custom models
2. **Pick dataset / benchmark** — upload, select from public benchmarks, or pick your private dataset
3. **Pick scoring** — code graders, judges, or both
4. **Preview cost** — Stratix shows worst-case ECU consumption before you run
5. **Run** — queue and watch results stream in

## Browsing past runs

Filters in the sidebar:

* Date range
* Model
* Benchmark / dataset
* Scorer / judge
* Status (queued, running, completed, failed)
* Tags

Each row shows: name, model, benchmark, top-line score, status, ECU consumed, "compare" button.

## Comparing runs

Select 2+ rows and click **Compare**. The comparison view shows:

* Side-by-side score tables
* Per-row deltas (where they ran on the same dataset)
* Cost and latency comparison

## Run a comparison against the public catalog

The compare-models view in Premium is identical in shape to Stratix Public's compare-models — you can compare your BYOK custom model against any public model.
