Vercel Integrates Liquid d1 Decision Model for Structured Classification and Vision Scoring

Vercel AI Gateway has integrated Liquid AI's d1 decision model, enabling developers to obtain probabilistic structured answers via standard APIs.

Unlike traditional LLMs, d1 does not generate free-form text but directly returns judgments for predefined typed questions (such as booleans, choices, or scores). The model also supports vision inputs for image classification and quality inspection.

Developers can access it through the AI SDK, OpenAI-compatible interface, or TypeSafe API. All decision requests are included in Gateway's unified logging and budget management system for cost control.

This is a platform integration announcement; no independent third-party performance benchmarks were provided.
