How to Evaluate LLM Performance for Domain-Specific Use Cases

1. Prompts.ai

Prompts.ai

Prompts.ai is a centralized platform that brings together over 35 leading AI models - including GPT-5, Claude, LLaMA, and Gemini - into a secure and user-friendly interface. It’s designed to help enterprises evaluate and optimize large language models (LLMs) seamlessly. Below, we’ll explore its standout features in interoperability, governance, cost management, and scalability.

Interoperability

Prompts.ai simplifies the complexity of managing AI workflows by consolidating API connections and authentication into one platform. Its advanced API framework integrates directly with CI/CD pipelines and machine learning operations, making it easier to automate the evaluation of LLM outputs during deployment.

Governance & Compliance

Prompts.ai is built with enterprise-grade governance in mind, addressing the stringent security and compliance needs of Fortune 500 companies and regulated industries. It adheres to key standards, including SOC 2 Type II, HIPAA, and GDPR, ensuring data protection at every stage of the evaluation process. The platform officially launched its SOC 2 Type II audit on June 19, 2025, and provides real-time compliance monitoring through its Trust Center (https://trust.prompts.ai/). With full visibility into all AI interactions, organizations can maintain detailed audit trails to meet regulatory requirements.

Cost Transparency

Using a FinOps-driven approach, Prompts.ai links costs directly to usage, offering real-time dashboards to track spending, forecast monthly expenses, and identify cost-saving opportunities. Its flexible Pay-As-You-Go TOKN credits system eliminates subscription fees, making budgeting straightforward. For example, a customer service LLM handling 10,000 daily queries can see a 30% improvement in accuracy within weeks and a reduction of 3,000 escalations, significantly enhancing operational efficiency.

Scalability & Usability

Prompts.ai is designed to handle high-volume evaluations with ease. It supports batch processing, parallel evaluations, and auto-scaling, allowing it to process thousands - or even millions - of outputs daily. The platform’s user-friendly interface includes customizable dashboards, role-based access, and exportable results, catering to both technical and non-technical teams. With automated evaluations and instant feedback, development speeds can increase up to 10 times faster. Additionally, guided workflows and customizable templates make it easy for teams to get started without a steep learning curve.

2. EvalGPT

EvalGPT

EvalGPT, developed by H2O.ai, is an open-source platform designed to compare the performance of large language models (LLMs) across a variety of tasks. It provides transparency and allows users to create tailored evaluation workflows.

Interoperability

Built with an open-source framework, EvalGPT can be seamlessly integrated into development pipelines, offering organizations the flexibility to adapt it to their specific needs. By utilizing GPT-4 for A/B testing, the platform automates evaluation tasks - such as summarizing financial reports or answering queries - making it a natural fit for existing AI systems. This adaptability enhances its ability to scale and supports extensive customization.

Scalability and Usability

EvalGPT's design is built to handle scalability while remaining user-friendly. Teams can adjust the evaluation framework to accommodate varying workloads and incorporate custom benchmarks that align with their unique business goals. The platform enables simultaneous processing of multiple models, delivering comparative insights to identify the best-performing LLM for a given application. This approach ensures that evaluation outcomes directly contribute to better performance in real-world production settings.
