What is SmolLM2-1.7B-Instruct?

OMW evidence review3 Oct 2026

Open Model Weights records SmolLM2-1.7B-Instruct as a 1.71138B-parameter text open-weight model in the SmolLM2 family, with HuggingFaceTB listed as the developer. The checked source repository provides 10 recognized weight artifacts, format evidence for Safetensors, PyTorch, ONNX and a verified context window of 8,192 tokens. Values that are not evidenced in the checked sources remain explicitly undisclosed or unknown.

The repository declares Apache-2.0. Commercial use allowed under Apache-2.0 conditions. Open Model Weights reports the checked license evidence and classification; this is not legal advice.

Lineage metadata declares HuggingFaceTB/SmolLM2-1.7B as a related base model with the relation declared relationship. In the checked repository, training or recipe evidence is present.

LINEAGE & PROVENANCE

What the checked sources disclose — and what they do not.

Open Model Weights does not infer a hidden base model or training corpus when the checked sources do not declare one.

RUNTIME SIGNALS

Compatibility claims stay attached to their evidence level.

Declared and model-card-mentioned runtimes are discovery signals. They are not treated as Open Model Weights runtime tests unless explicitly measured.
