LXT AI model evaluation project process
Every AI model evaluation project at LXT follows a structured, transparent workflow designed for scalability, precision, and continuous improvement – from initial consultation to final delivery.
We begin with a detailed consultation to understand your AI model, evaluation goals, and specific risk areas. Together, we define target tasks, locales, and KPIs to ensure every metric reflects your success criteria.
Our team designs a tailored evaluation workflow — selecting the right evaluator profiles based on language, expertise, and domain relevance. We implement screening filters, NDAs, and access controls to meet your security and compliance needs.
LXT collaborates with your teams to create clear evaluation rubrics, examples, and gold-standard references. A pilot phase then calibrates evaluators for consistency and establishes inter-rater agreement benchmarks.
Once approved, the project scales through our managed global workforce. Human evaluators assess outputs for accuracy, fairness, and safety, while automated systems handle task routing, sampling, and progress tracking.
Multi-layer QA ensures reliability at every stage — including seeded gold tasks, peer reviews, statistical audits, and live analytics dashboards for transparent performance monitoring.
Final evaluation results are securely transferred in the format you prefer — via API, data feed, or encrypted file delivery. Structured outputs include all agreed metrics and metadata, enabling seamless integration with your internal analytics tools or model management systems.
For ongoing or recurring projects, LXT provides continuous evaluation cycles to monitor post-deployment model performance and maintain data quality over time. Workflows can be scaled, automated, or repeated at defined intervals to ensure your AI remains accurate, safe, and compliant as it evolves.

Secure services for
AI model evaluation
Evaluating AI model outputs often involves sensitive information — from proprietary model responses and datasets to user-generated content and confidential domain data. At LXT, data protection is built into every stage of our AI model evaluation workflows.
Our ISO 27001 certification and SOC 2 compliance ensure enterprise-grade security and strict governance over how data is accessed, processed, and stored.
For highly sensitive evaluations, LXT offers secure facility options – where vetted specialists perform all tasks in controlled environments, with no access by the broader crowd. This is ideal for projects involving confidential algorithms, regulated data, or safety-critical applications.
Whether through our managed global workforce or inside secure facilities, we design every AI model evaluation project to meet your privacy, compliance, and operational requirements — without compromising speed, scale, or quality.
