Liquid d1

Liquid AI released d1 on 29 September 2026, a decision model which classifies, routes, and scores inputs without producing any output tokens. Instead of generating text, it outputs numeric answers and bills only for input tokens, targeting use cases such as content moderation, ticket triage, safety guardrails, and agent tool-call approvals. The model supports Noul yes/no questions, Choice selections across named options, and Score ratings on an ordered scale, all combinable in a single call. It offers a 32,000-token context window, proprietary hosted API access, no downloadable weights, and no fine-tuning. Access is available through Liquid's API and Vercel AI Gateway under the model ID liquid/d1, with OpenRouter support planned.
