Google Introduces Stax for AI Evaluation

Google has launched Stax, a new AI evaluation platform designed to streamline the evaluation process for AI models, as announced in a company blog post. Stax aims to replace subjective testing methods with data-driven evaluations, enabling developers to make informed decisions about their AI products.

Stax offers a comprehensive toolkit for AI evaluation, allowing users to conduct repeatable and insightful evaluations from initial experiments to production releases. The platform supports the creation of custom evaluators tailored to specific product needs, moving beyond generic benchmarks.

The platform also provides out-of-the-box autoraters to assess common metrics such as coherence and factuality, and allows developers to build their own autoraters to meet unique criteria. This flexibility helps developers ensure their AI systems align with specific brand voices or application rules.

Stax is designed to help developers quickly compare models, track AI performance visually, and monitor improvements, ultimately facilitating faster and more confident deployment of AI features.
