Open-weight 2B decision model on LFM3-VL for typed answers about text, images and video

d1-2B is an open-weight decision model from Liquid AI (LFM Open License v1.0, 1.92B parameters): it answers typed questions, such as yes or no, pick one or pick several, with probabilities instead of writing text. There's no hosted version: you run it on your own hardware. JevBench, the main independent benchmark, doesn't list it yet.

- Made by: Liquid AI
- Weights: Open, LFM Open License v1.0
- Size: 1.92B
- Where: Self-host only
- Images: Yes
- Context: 128K
- Fine-tuning: Fine-tunes on a single GPU (Liquid AI)
- Docs: https://docs.liquid.ai/lfm/models/d1-2b

## d1-2B price
