AI/ML testing validates that machine learning models produce accurate, unbiased, and safe outputs in production. It covers model accuracy evaluation, bias detection, hallucination testing, adversarial robustness, and production monitoring. ### Does Mtest Labs hold security clearance? Yes. Mtest Labs practitioners hold SC and NATO Secret clearances for classified UK government and defence AI/ML programmes. We are a G-Cloud 14 approved supplier. ### Which companies has Mtest Labs tested for? Google Arts and Culture (10+ years), Tesco Hudl tablet programme, Faxi (Toyota), and Zenly (Snap Inc.). ### What areas does Mtest Labs cover? We serve clients across the United Kingdom, Europe, and the United States from our London and Delaware offices. ### How much does AI/ML testing cost? Costs vary based on scope, model complexity, and engagement duration. Mtest Labs offers dedicated team placement, sprint-based testing, and ongoing retainer arrangements with transparent pricing. ### What testing frameworks and tools does Mtest Labs use? We use Selenium, Cypress, Playwright, Appium, custom LLM evaluation frameworks, BrowserStack, and real device labs. Our approach is tool-agnostic — we adapt to your existing tech stack. ### How long does a typical AI testing engagement take? A focused AI model validation sprint runs 2-4 weeks. Ongoing embedded QA partnerships range from 3 months to multi-year engagements. Our Google relationship has lasted 10+ years. ### Do you offer remote testing services? Yes. Both remote and on-site testing services are available. For government projects, we deploy SC-cleared engineers to approved secure locations. ### What is hallucination testing? Hallucination testing validates that AI outputs are grounded in real data and don't fabricate information — checking for invented citations, fabricated statistics, and incorrect factual claims. ### What is included in the QA Academy? A self-paced 3-4 month programme: testing fundamentals, AI/ML model validation, platform automation, and live client project placement with ISTQB CT-AI certification preparation. ### Can I hire QA engineers directly from Mtest Labs? Yes.
