zenlm/zen3-asr

Zen3 ASR

Zen3 automatic speech recognition model for transcription, voice agents, and streaming. ~1.7B parameters; a 24-layer audio encoder feeds a Qwen3 text decoder. The config declares support for 30 languages.

Derived by fine-tuning `Qwen/Qwen3-ASR-1.7B` (Alibaba Cloud, Apache-2.0).

• —Architecture: Qwen3ASRForConditionalGeneration (qwen3_asr)
• —Parameters: ~1.7B
• —Base model: `Qwen/Qwen3-ASR-1.7B`

Weights

This repository contains the model weights: sharded weights model-0000{1,2}-of-00002.safetensors with model.safetensors.index.json, config and tokenizer files.

The model uses the qwen3_asr architecture and loads with transformers (>= 4.57). It is API-compatible with the upstream base — follow the inference recipe on the base model card `Qwen/Qwen3-ASR-1.7B`.

Provenance
