# Schematron V2 Small

> Schematron V2 Small is inference.net's 3B extraction model that turns messy HTML into clean JSON that conforms to a schema you supply. It offers the family's highest extraction quality, approaching frontier-model accuracy on complex schemas and long pages. 128K-token context, strict JSON schema output.

## Model card

- Total parameters: 3B [2]
- Native context: 128000 tokens [1]

### Strengths [1]

- Highest extraction quality in the Schematron V2 family, approaching frontier-model accuracy on complex schemas.
- Strict JSON mode with full schema adherence.

### Known limits [1]

- Takes no system or user instructions; the JSON schema alone drives extraction, so ambiguous fields need explicit descriptions in the schema.
- Pages longer than the 128K context must be chunked or truncated.

### Use cases [1]

- Complex schemas or very long pages where extraction accuracy matters most.

### API notes [1]

- Send raw HTML as the user message and set response_format to json_schema with strict true.
- Keep temperature at 0; the model is trained to perform best there.
- Clean HTML with lxml first (drop scripts, styles and boilerplate) to match the training data.
