Run the same prompt across GPT-5, Claude 4.5, and Gemini 2.5 Pro. Score outputs against your rubric. Promote the winning configuration straight to production — and pin it so nothing drifts.
GPT-5, Claude 4.5, Gemini 2.5 Pro, Flash, and Lite — fully routed through the Lovable AI gateway. No keys to wrangle.
Score outputs on accuracy, tone, length, and your custom criteria. Aggregate across human reviewers or use an AI judge.
The winning combination — model, parameters, and prompt version — gets pinned to your prompt's production track. Roll back any time.
Every output ships with token, cost, and latency metrics. See the price of being right before you ship it.
Pick a prompt, choose models, set rubric weights.
All models execute in parallel. Outputs stream live.
Reviewers (or the AI judge) score each output.
Winning config is pinned to production with one click.
We replaced two weeks of model debate with one Friday afternoon. Bakeoffs gave us receipts — and saved us 38% on inference.
Every frontier model on the Lovable AI gateway — GPT-5, GPT-5 mini, Claude 4.5, Gemini 2.5 Pro, Flash, and Lite. New models appear automatically as we add them.
No. The gateway is included with Prompsy. You can also bring your own keys per workspace if you prefer.
Yes — bring a custom endpoint and we'll route to it alongside frontier models.
We randomize output order, hide model names, and let you set rubric weights. You can also require human-in-the-loop scoring for production-bound prompts.
