Execute your defined task against a meticulously curated catalog of over 100 leading models from providers like OpenAI, Anthropic, Google, and open-source communities in one coordinated session. Crucially, every test makes a live API call, ensuring you compare real latency, real costs, and real, current model performance—not cached or idealized marketing numbers. This delivers an authentic, apples-to-apples comparison under identical conditions.

Comprehensive Performance Analytics

Gain insights beyond simple pass/fail metrics with a detailed analytics dashboard. View side-by-side comparisons of each model's quality score (as defined by your task), the actual cost per request, response latency, and token usage. This holistic view enables you to evaluate the true cost-efficiency of a model: the quality it delivers relative to the price you pay for each API call.

Variance and Stability Testing

Understand not just if a model can complete a task, but if it will do so reliably every time. OpenMark runs your prompts multiple times for each model, analyzing the variance in outputs. This reveals consistency—or a lack thereof—highlighting models that may produce a stellar result once but fail unpredictably, a critical factor for production systems where stability is non-negotiable.

How does OpenMark AI calculate the quality score for a model's output?

OpenMark employs a sophisticated, task-aware evaluation system. For many standard tasks, it can use automated metrics or LLM-as-a-judge scoring against your defined success criteria. For highly custom evaluations, you can implement manual scoring or rubric-based checks within the platform. The score reflects how well the output meets the specific objectives of your described task, not a generic capability.

Do I need API keys for the models I want to test?

No, one of OpenMark's primary advantages is that it abstracts away API key management. You operate using OpenMark credits. The platform handles all the underlying API calls to the various model providers on your behalf. This simplifies setup dramatically and allows for instantaneous testing across competitors without configuring multiple accounts.

What is meant by testing "stability" or "variance"?

Stability testing refers to running the same prompt against the same model multiple times (in parallel or sequentially) and analyzing the differences in the outputs. A model with low variance produces very similar, high-quality results each time, which is crucial for production. High variance indicates unpredictability, where a model might give a perfect answer once but a poor or irrelevant one the next, representing a significant operational risk.

Can I benchmark private or fine-tuned models?

The current public catalog focuses on widely available, hosted foundation and proprietary models from major providers. For benchmarking private, fine-tuned, or self-hosted models, you would typically need to integrate them via a compatible API endpoint, which may be available through enterprise or custom plans. The platform's architecture is designed to accommodate a wide range of model sources.
