Libraries

How to use LiquidAI/LFM3-VL-2B-FP8 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="LiquidAI/LFM3-VL-2B-FP8", trust_remote_code=True)
messages = [
    {
        "role": "user",
        "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("LiquidAI/LFM3-VL-2B-FP8", trust_remote_code=True, device_map="auto")

LFM3-VL-2B-FP8

FP8 version of LFM3-VL-2B for GPU inference.

Language feed-forward and attention weights use FP8 with 128×128 blocks and dynamic activation quantization. Embeddings, the output head, convolutions, attention gates and norms stay in BF16. The vision encoder and projector also stay in BF16. Sliding-window and RoPE settings are unchanged.

Find architecture and usage details in the original model card.

Use with SGLang

Support for LFM3-VL in SGLang is in review in sgl-project/sglang#46858. We will update this card when a release supports it.

python -m sglang.launch_server \
  --model-path LiquidAI/LFM3-VL-2B-FP8 \
