This is super compelling, especially the focus on reproducible results and real cost efficiency. Testing models against your own prompts without LLM-as-judge feels like a much more honest way to choose the right model.
Built OpenMark AI after finding a cheaper model beat a 'flagship' one for my task. Stop trusting generic benchmarks, test models on YOUR prompts with deterministic scoring, real costs & 100+ models.
@kean this is very timely. I could have used this when I chose gpt-4o for a client's agentic flow several.months ago, but found out months later that 4.1-mini was performing better for his use case AND much cheaper....
@theaspirinv thank you ! This is verbatim what happened to me 8 months ago. Built a rag pipeline and found out using cheaper models would actually perform better! So i made this benchmarking tool. Now I regularly use it to check for drift.
