# Compare two models

Compare any two models head-to-head across a shared benchmark — no signup needed.

Putting two models side-by-side is one of the highest-leverage things Stratix does. Use it during model selection, when a new model drops, or when leadership asks "is X better than Y."

## Steps

### 1. Open Compare models

Go to [`stratix.layerlens.ai/compare-models`](https://stratix.layerlens.ai/compare-models).

### 2. Pick the first model

Search and select a model in the left column. The page populates with that model's benchmark scores.

### 3. Pick the second model

Same in the right column. The page now shows both models' scores on every benchmark either has been evaluated against.

### 4. Read the comparison

The score table highlights:

* Where each model wins (green)
* Where they tie (gray)
* Where the gap is large vs small

### 5. Pick a benchmark to focus on

Click any benchmark row to drill into the comparison for that benchmark — including raw scores, sample inputs, and (where available) sample outputs from each model.

### 6. Save the comparison URL

The URL contains both model IDs. Bookmark it or share with your team.

## Verify

You should be able to compare GPT-5.3 vs Claude Opus 4.6 on MMLU and see both models' scores on the same row.

## Common patterns

* **Frontier vs cost-optimized.** Compare a frontier model against a smaller, cheaper one for tasks where you suspect the smaller model is good enough.
* **Provider against provider.** Compare an OpenAI model against an Anthropic model on the benchmark closest to your use case.
* **Old vs new generation.** When a new generation drops, compare it against the predecessor on benchmarks you care about.
