Liquid AI d1
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 with a 32K context and run on llama.cpp, vLLM, SGLang and Ollama. Liquid also serves it on Liquid Console, OpenRouter and Vercel AI Gateway.
The hosted API costs $0.02 per 1M input tokens, with output free and $2 of credit for new organizations. The weights are free to use until a company's annual revenue passes $10 million.
