Diverse Persona Testing at Scale

Simulate thousands of production-like interactions using a vast library of synthetic user personas, such as an International Caller or a Digital Novice. This feature enables testing from the perspective of diverse real human behaviors, needs, and backgrounds, ensuring your AI agent performs effectively and empathetically for every segment of your user base.

Actionable Evaluation with Risk Scoring

Gain deep, actionable insights into your AI agent's performance with detailed evaluations on key metrics like Effectiveness, Accuracy, Empathy, and Professionalism. Integrated regression testing includes a risk scoring system that highlights potential areas of concern, allowing teams to prioritize critical issues and optimize testing efforts efficiently.

LLMWise

Smart Routing

LLMWise's smart routing feature intelligently directs prompts to the optimal model based on the task at hand. This means that coding queries go to GPT, creative writing tasks are sent to Claude, and translation requests are managed by Gemini. This targeted approach ensures that users receive the most accurate and contextually relevant responses, enhancing the overall effectiveness of their applications.

Compare & Blend

With the compare and blend functionality, users can run prompts across different models side-by-side. This feature allows for a direct comparison of responses, enabling developers to identify the best outputs. The blend option takes it a step further by synthesizing the most effective parts of each model's response into a single, stronger answer, maximizing quality and insight.

Always Resilient

Reliability is at the core of LLMWise. The always resilient feature includes a circuit-breaker failover mechanism that automatically reroutes requests to backup models in case a primary provider experiences downtime. This ensures that applications remain functional without interruption, providing a seamless user experience and peace of mind for developers.

Test & Optimize

LLMWise offers robust testing and optimization tools, including benchmark suites, batch tests, and optimization policies focused on speed, cost, or reliability. Automated regression checks ensure that the performance of integrated models remains consistent over time, allowing developers to fine-tune their applications effectively and efficiently.

Use Cases

Agent to Agent Testing Platform

Pre-Production Validation of Customer Service Bots

Before launching a new customer support chatbot, enterprises can use the platform to simulate thousands of customer inquiries, from simple FAQs to complex, emotional, or multi-intent issues. This validates the bot's accuracy, tone, escalation logic, and ability to avoid hallucinations or toxic responses, ensuring a safe and effective rollout.

Compliance and Safety Assurance for Financial Assistants

For AI agents in regulated industries like finance or healthcare, the platform is crucial for testing compliance with data privacy rules, detecting potential bias in financial advice, and ensuring no policy violations occur during voice or chat interactions. Autonomous agents continuously test for these critical failures.

End-to-End Testing of Multimodal Shopping Assistants

Test an AI shopping assistant that uses images, voice, and text to interact with users. The platform can generate scenarios where a user uploads a photo, asks a follow-up question via voice, and requests a phone callback, validating the agent's seamless integration across all modalities and conversation turns.

Continuous Regression Testing for Evolving AI Agents

As an AI agent is updated with new data, models, or capabilities, the platform provides automated regression testing. It re-runs a comprehensive suite of scenarios to immediately detect regressions in intent recognition, personality tone, or reasoning, maintaining quality and performance with every release.
