huihui-ai/Huihui-MoE-5B-A1.7B-abliterated

Model Overview

Huihui-MoE-5B-A1.7B-abliterated is a Mixture of Experts (MoE) language model developed by huihui.ai, built upon the huihui-ai/Qwen3-1.7B-abliterated base model. It enhances the standard Transformer architecture by replacing MLP layers with MoE layers, each containing 4 experts, to achieve high performance with efficient inference. The model is designed for natural language processing tasks, including text generation, question answering, and conversational applications.

Note

huihui-ai/Huihui-MoE-4.8B-A1.7B-abliterated Because tie_word_embeddings=True, the parameters for the lm_head were not saved, which causes ollama to be unable to use it. Therefore, this version supports ollama.

This model combines four ablated models, and perhaps it can achieve the performance of all the ablated models?

This is just a test. The exploration of merging different manifestations of models of the same type is another possibility.

• Architecture: Qwen3MoeForCausalLM model with 4 experts per layer (num_experts=4), activating 1 expert per token (num_experts_per_tok=1).
• Total Parameters: ~5 billion (5B)
• Activated Parameters: ~1.72 billion (1.7B) during inference, comparable to Qwen3-1.7B-abliterated
• Developer: huihui.ai
• Release Date: June 2025
• License: Inherits the license of the Qwen3 base model (apache-2.0)

Instruction Following:

huihui-ai/Qwen3-1.7B-abliterated

Training

• Base Model: Qwen3-1.7B-abliterated
• Conversion: The model copies embeddings, self-attention, and normalization weights from Qwen3-1.7B-abliterated, replacing MLP layers with MoE layers (4 experts). Gating weights are randomly initialized.
• Fine-Tuning: Not fine-tuned; users are recommended to fine-tune for specific tasks to optimize expert routing.

Applications

• Text Generation: Articles, dialogues, and creative writing.
• Question Answering: Information retrieval and query resolution.
• Conversational AI: Multi-turn dialogues for chatbots.
• Research: Exploration of MoE architectures and efficient model scaling.

Limitations

• Fine-Tuning Required: Randomly initialized gating weights may lead to suboptimal expert utilization without fine-tuning.
• Compatibility: Developed with transformers 4.52.4; ensure matching versions to avoid loading issues.
• Inference Speed: While efficient for an MoE model, performance depends on hardware (GPU recommended).

Ethical Considerations

• Bias: Inherits potential biases from the Qwen3-1.7B-abliterated base model; users should evaluate outputs for fairness.
• Usage: Intended for research and responsible applications; avoid generating harmful or misleading content.
