Frequently Asked Questions

Questions about LLMKnights that you were always afraid to ask.

LLM Knights is a platform for testing and comparing large language models (LLMs) across each other. Also, you can test the same model with different parameters to see how they affect the output. It provides a way to find the best model for your specific use case by evaluating speed, cost, and accuracy metrics side-by-side.

Yes. Each run is designed to make tradeoffs visible so you can judge whether a faster or cheaper model is still accurate enough for the task.

No. It's created by a team of engineers and AI enthusiasts who are passionate about making LLM testing accessible and efficient for everyone. We have a median experience of 20 years in software development, and we are committed to providing a reliable, bug-free (as much as possible) and user-friendly platform. That said, all the decisions are made by human beings.

No. The free tier gives you starter credits so you can test the workflow, compare baseline models, and see how results are tracked.

One credit represents a single limited text test against a free or budget model and. Heavier models and richer workloads can consume more depending on the model, its type (video and image generation usually consume more), and the size of the input.

Yes. The testing flow is built for repeatable experiments, so you can vary generation parameters and compare how output quality and consistency change. Not all the models support the same parameters, so the platform will only show the relevant options for each model.

Yes, the input and output can be whatever you want (depending on the model).

Not right now, but in the future, the platform will support both UI-driven testing and programmatic workflows for teams that want benchmarking inside their own pipelines.

The platform is positioned for serious evaluation work, so privacy and controlled access matter. Sensitive prompts, outputs, and run history all stay scoped to your account and workflow. We never share your data with other users or third parties, and we do not use your prompts or outputs to train our models. But if you want, you can share your results with the community to help others learn from your experiments (see below).

There are several ways to get more credits. You can purchase additional credits through the platform, or you can earn credits by contributing to the community (sharing your test results can bring you from 5 to 20 credits). Also, we will run referral and affiliate programs that allow you to earn credits by inviting others to join the platform. We also offer special promotions and discounts from time to time, so keep an eye out for those.
