AI model comparison

Compare model outputs side by side.

Run the same prompt across multiple models, inspect where they agree or diverge, and review judge passes in one workspace.

What it does

Everything you need to evaluate models.

Multi-model runs: Send one prompt to GPT-4o, Claude, Gemini, and more — all at once. Answers appear in parallel columns.
Judge evaluation: Let a judge model grade responses automatically and surface which model performs best on your task.
Prompt history: Every run is saved. Revisit past comparisons, tweak the prompt, and re-run to track how outputs change.
Streaming responses: Watch model outputs stream in real time across all columns simultaneously — no waiting for slow models.
Model parameters: Adjust temperature, top-p, max tokens, and other parameters per model to isolate exactly what changes output.
System prompt control: Set a shared or per-model system prompt to test how instruction following varies across providers.

How it works

01
Write your prompt.
Type any question, task, or instruction. Optionally set a system prompt or adjust per-model parameters before running.
02
Select your models.
Pick two or more models from the supported list — GPT, Claude, Gemini, Mistral, and more. Responses stream in side by side.
03
Review and compare.
Read outputs in parallel, run a judge pass to get an automatic verdict, or refine your prompt and run again.
