canary-qwen-2.5b GGUF

GGUF conversions of nvidia/canary-qwen-2.5b for use with CrispASR.

Model

SALM (Speech-Augmented Language Model): 32-layer FastConformer encoder (d=1024) + linear projection (1024 to 2048) + Qwen3-1.7B LLM decoder with merged LoRA. English ASR, up to ~40s audio.

• Parameters: 2.5B
• Encoder: FastConformer (from canary-1b-flash), 128 mel bins, 16 kHz
• LLM: Qwen3-1.7B (28 layers, GQA 16/8, SwiGLU)
• LoRA: merged at conversion time (r=128, alpha=256)
• Language: English only
• License: CC-BY-4.0

Files

| File | Quant | Size | Notes |

|------|-------|------|-------|

| canary-qwen-2.5b-f16.gguf | F16 | 5.70 GB | Full precision |

| canary-qwen-2.5b-q8_0.gguf | Q8_0 | 4.38 GB | LLM blocks quantized, encoder F16 |

| canary-qwen-2.5b-q4_k.gguf | Q4_K | 3.67 GB | LLM blocks quantized, encoder F16 |

Encoder and projection weights are kept at source precision (F16/F32) in all quantized variants to avoid conformer drift.

Usage

# With CrispASR CLI
crispasr --backend canary-qwen -m canary-qwen-2.5b-q8_0.gguf -f audio.wav

# Auto-download
crispasr --backend canary-qwen -m auto --auto-download -f audio.wav
