Choose the right modelbefore production
Compare local and API models against real prompts, skills, and expected outputs.
Compare real outputs
Run the same prompt across selected models.
Test local and API models
Evaluate downloaded models next to paid providers.
Score against expectations
Define the target result and find the closest match.
Decide with evidence
Choose based on fit, not guesswork.
Evaluate the models your product depends on.
Compare local and hosted models on the same prompts before you build.
MEASURE TWICE. CUT ONCE.
Built for model decisions
Run the same task across local and API models, compare real outputs, and choose the model that fits your product before you ship.
Evaluate models before you ship
Test local and API models
Add downloaded models and API providers to the same evaluation workflow.
Use real product prompts
Run the exact task your app needs, not a synthetic benchmark.
Compare outputs side by side
Send one prompt to selected models and inspect the answers in Arena.
Score against expectations
Define the input, expected output, and rubric before Evalvo scores the results.
Decide with evidence
Use scores, issues, and charts to choose the model that fits production.
