Open-weight 3B decision model on LFM2.5-VL: typed answers over text, JSON and images in one forward pass

d1 is Liquid AI's open-weight decision model, a 3B model built on LFM2.5-VL-3B. Given a state of text, JSON or images and a set of yes/no, choice or score questions, it returns typed answers with probabilities in one forward pass, with zero output tokens.

The weights are on Hugging Face (32K context) and run on llama.cpp, vLLM, SGLang and Ollama. Liquid serves d1 on its console, OpenRouter and Vercel AI Gateway at $0.02 per 1M input tokens, and the larger d1-ultra at $0.042. Output is free; new organizations get $2 of credit.
