Model Overview
Description:
The
txn545/Qwen3.5-35B-A3B-NVFP4 model is a quantized version of Alibaba's Qwen3.5-35B-A3B model, an auto-regressive language model that uses an optimized transformer architecture. For more information on the base model, please check

Post Training Quantization
This model was obtained by quantizing the weights and activations of Qwen3.5-35B-A3B to NVFP4 data type, ready for inference with SGLang. Only the weights and activations of the linear operators within transformer blocks in MoE are quantized.
Usage
To serve this checkpoint with
SGLang, you need to use the latest main branch with
this PR and run the sample command below:
1python -m sglang.launch_server --model txn545/Qwen3.5-35B-A3B-NVFP4 --quantization modelopt_fp4 --trust-remote-code

Model Limitations:
The base model was trained on data that contains toxic language and societal biases originally crawled from the internet. Therefore, the model may amplify those biases and return toxic responses, especially when prompted with toxic prompts. The model may generate answers that may be inaccurate, omit key information, or include irrelevant or redundant text producing socially unacceptable or undesirable text, even if the prompt itself does not include anything explicitly offensive.
Ethical Considerations
Trustworthy AI is a shared responsibility. When downloaded or used in accordance with the Apache 2.0 license, developers should work to ensure this model meets requirements for the relevant industry and use case and addresses unforeseen product misuse.
