Promptfoo: compare outputs and assertion failures side by side
Original documentation viewer image with twelve demonstration cases, Model A columns, outputs and assertion explanations. Passing percentages, token/latency figures and the 2025 eval ID belong to the author demo; they are not current-model rankings, real provider benchmarks or results of the separate recipes below.

Promptfoo: inspect pass rates and score distributions
Original documentation chart illustration for pass rate, score distribution and pairwise prompt scores. These figures explain viewer controls, not a measured benchmark or evidence that one named model is better. The complete source image is retained, with no invented underlying dataset.

Promptfoo: complete structured-output evaluation config
Complete author YAML for two math cases and alternative JSON response schemas. Keep only providers you can access, configure their keys and replace Azure host/deployment placeholders. Model names, API version and schema options are source configuration requiring current provider support; expected assertions are not passing test results. No evaluation was run.

Promptfoo: evaluate separate multi-turn conversation threads
Complete paired YAML and prompt.json Nunjucks template. Save both files together, configure provider access and run in the matching Promptfoo setup. The .json file intentionally contains template loops, not standalone JSON. Conversation IDs separate the example threads; no model answers, factual accuracy or current provider compatibility were verified here.

Ce que propose Promptfoo
- 01Compare prompts and model outputs
- 02Define repeatable evaluation cases
- 03Run red-team checks and CI workflows
Ce qui le distingue
It organizes test cases and checks; meaningful results depend on the chosen datasets, assertions and providers. Evaluations using external APIs can send data to those providers.
Texte original de la source · ENÀ qui il convient
- Developers evaluating AI applications
- Teams maintaining repeatable model checks
Points à vérifier
- Tester une vraie tâche et comparer le résultat à ses besoins.
- Vérifier quelles données sont conservées, partagées ou utilisées pour l’entraînement.
- Confirmer les tarifs, limites d’usage et conditions de résiliation sur le site officiel.
