What's The Best LLM For...
Best LLM For simplifies one of the biggest challenges in AI product development: choosing the right language model for your specific use case. Instead of writing custom scripts or relying on generic benchmarks and leaderboards, we help you run customized, side-by-side comparisons of top models using your own prompts.
Whether you're searching for the best coding LLM, the best open source model for data analysis, or the best LLM for creative writing, it's important to understand:
- Which model performs best at your specific tasks
- How consistently each performs across inputs
- Whether quality improvements justify costs
- Which differences actually matter to users
"Best LLM For" helps you explore these questions by making it easy to evaluate many of the top proprietary and open-source models against custom, application-specific metrics, all through an easy-to-use web interface.
In short, it helps you find the LLM that best meets your goals.
How It Works
"Best LLM For" guides you through a structured four-stage process:
-
Create: Name your experiment and describe your evaluation goals. For example, you might be testing "Python code generation accuracy across models" or "technical documentation summarization quality."
-
Upload: Upload a CSV file with prompts representative of your intended use case. The platform validates your data and provides a preview of your test set.
-
Generate: Select which models to test, then generate responses to your prompts across all selected models. This creates controlled experiments where each model processes identical inputs under the same conditions.
-
Evaluate: Define evaluation criteria specific to your use case, then analyze how each model performs. The platform provides statistical analysis, cost comparisons, and detailed breakdowns to guide your decision.
Save experiments to revisit later, adjust your prompt set or evaluation metrics, and rerun comparisons as new models are released.
Getting Started
If you have an account, and are signed in, you can access "Best LLM For" from Mandoline's Experiments page. Click "New" to begin testing models with your own prompts and requirements.
If you're a new user, and want to "kick the tires" before you sign up, you can run small-scale experiments here.
In either case, there is no required setup or coding needed. Just upload your test prompts and start running experiments within minutes. If you need any help, or have any feedback, we'd love to chat. Please reach out at support@mandoline.ai.
