SmolLM2-1.7B-Instruct-MNN

Pre-converted SmolLM2 1.7B Instruct in MNN format for on-device inference with TokForge.

Original model by HuggingFace, converted to MNN Q4 for mobile deployment.

Model Details

Architecture	LlamaForCausalLM (32 layers, 2048 hidden)
Parameters	1.7B (4-bit quantized)
Format	MNN (Alibaba Mobile Neural Network)
Quantization	W4A16 (4-bit weights, block size 128)
Vocab	49,152 tokens
Source	HuggingFaceTB/SmolLM2-1.7B-Instruct

Description

HuggingFace's own SmolLM2, an ultra-compact 1.7B model designed for on-device inference. Runs on any phone, even budget devices with 4GB RAM. Surprisingly capable for its tiny size, great for quick Q&A, text completion, and simple tasks where speed matters more than depth.

• Converted with llmexport from MNN by Alibaba (Apache-2.0).

Limitations

• Intended for TokForge / MNN on-device inference on Android
• This is a runtime bundle, not a standard Transformers training checkpoint
• Quantization (Q4) may slightly reduce quality compared to the full-precision original
