Libraries

How to use Intel/LongCat-Flash-Lite-Sparse-MXFP4-CT-AutoRound with Transformers:

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

pipe = pipeline("text-generation", model="Intel/LongCat-Flash-Lite-Sparse-MXFP4-CT-AutoRound")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import LongcatCausalLM
model = LongcatCausalLM.from_pretrained("Intel/LongCat-Flash-Lite-Sparse-MXFP4-CT-AutoRound", device_map="auto")

Configuration Parsing Warning:In UNKNOWN_FILENAME: "quantization_config.config_groups.group_0.format" must be a string

This model is an mxp4 model of LongCat-Flash-Lite-Sparse generated by intel/auto-round with RTN mode. Please follow the license of the original model.

Generate the Model

auto-round \
  meituan-longcat/LongCat-Flash-Lite-Sparse \
  --model_free \
  --scheme MXFP8 \
  --ignore_layers "lm_head,embed,self_attn,mlps,router,mtp" \
  --layer_config '{mlp.experts:{bits:4,data_type:mx_fp}}' \
  --format llm_compressor \
  --output_dir ./LongCat-Flash-Lite-Sparse-MXFP4

Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Therefore, before deploying any applications of the model, developers should perform safety testing.

Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
