        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoModelForImageTextToText
model = AutoModelForImageTextToText.from_pretrained("webbrain-one/lfm3-vld-2b", trust_remote_code=True, device_map="auto")

LFM3-VL-2B-VLD

LiquidAI/LFM3-VL-2B adapted with WebBrain's multipass VL-D (verify Yes/No per option + readout option code) decision protocol, distilled from LiquidAI/d1-2B on WebBrain multimodal browser workflow screenshots — without full VL/Compass fine-tuning (vision tower frozen, language backbone adapted via LoRA and merged to BF16).

Companion Repositories

webbrain-one/lfm3-vld-2b-onnx: WebGPU ONNX bundle (decoder_q8f16.onnx, decoder_q4f16.onnx with decision_hidden exposed, vision_encoder_fp16.onnx, and trained linear decision probes).
webbrain-one/lfm3-vld-2b-gguf: GGUF exports (BF16, Q8_0, Q4_K_M, and mmproj-F16) for llama.cpp (/v1/chat/completions + /v1/systemone).
webbrain-one/lfm3-vld-2b-lora: LoRA adapter (r=32, alpha=64) and projector weights.
