Can Plurai be deployed on-premise?

Yes, Plurai can be deployed in your VPC for maximum security, data control, and even lower latency.

What makes Plurai's SLMs accurate and cost-effective?

Plurai's SLMs are purpose-built for your specific tasks through intent calibration and synthetic data generation, achieving high accuracy with far lower latency and cost than general-purpose LLMs.

Do you only offer SLMs or other models as well?

In addition to purpose-built SLMs, we also offer optimized LLM-based evaluators for maximum accuracy at competitive cost, suitable for sampled data and offline evaluation.

Is Plurai's product only for evals and guardrails?

Our models can be used across a wide range of semantic tasks, including conversation evaluation, semantic similarity, grounding validation, policy compliance, and more.

What is Plurai

Plurai is a vibe-training platform for AI agent reliability, enabling developers to define agent behavior while automatically generating training data, validating it, and deploying a custom evaluation model in minutes. It replaces traditional annotation pipelines and prompt engineering with an intuitive process that feels like vibe coding, delivering sub-100ms latency at 8x lower cost than GPT-as-judge and over 43% fewer failures.

Key Features

Automatic generation of high-fidelity synthetic training data tailored to your use case

Deployment of purpose-built small language models (SLMs) for real-time guardrails and evals

Sub-100ms latency and 8x lower cost compared to GPT-based evaluations

No labeled data, annotation pipeline, or prompt engineering required

Always-on monitoring with continuous coverage, not sampled

Use Cases

AI agent builders who need custom guardrails to enforce safety and policy compliance in production
Startups that want to rapidly iterate and deploy reliable agents without expensive manual labeling
Enterprises requiring low-latency, cost-effective evaluation for conversational AI and customer-facing agents
Development teams seeking to automate testing across thousands of realistic scenarios before release

Why do startups need this tool?

Startups need Plurai to build trustworthy AI agents without the heavy cost and complexity of traditional evaluation pipelines. By automating data generation and deploying custom models in minutes, Plurai enables rapid iteration and production-grade reliability at a fraction of the cost, helping startups gain user trust and scale confidently.
