Model Card

Schematron V2 Turbo is a 3-billion-parameter model from Inference.net built to turn messy HTML into JSON matching a schema you supply, using schema-constrained decoding so the output is valid JSON by construction rather than by retry.

It's the throughput-optimized sibling to Schematron V2 Small, handling 4.14 requests per second on a single H100 versus Small's 2.47, a 2.5x gain over the original Schematron 3B. It shares Small's 128,000-token context but doubles its output limit, to 8,192 tokens.

On Inference.net's quality benchmark it scores 4.039 out of 5, close to Small's 4.060, and both beat DeepSeek V3.2 and GPT-5.4 Nano on extraction accuracy. On SimpleQA, a web-search factuality benchmark, it reaches 79.42 against Small's 83.10.

It suits web scraping and data extraction pipelines that prioritize speed and cost; the endpoint doesn't support tool calling.

Schematron V2 Small

Schematron V2 Small is a 3-billion-parameter HTML-to-JSON extraction model from Inference.net, fine-tuned from Meta's Llama 3.2 3B. It takes a JSON schema and raw HTML as input and returns schema-conformant structured output; extraction instructions go through the schema itself rather than a system or user prompt. Inference.net built it as the quality-focused tier of its V2 lineup, approaching 8B-level accuracy at roughly 3B-level speed, alongside a faster Turbo variant. On Inference.net's internal LLM-as-judge benchmark it scores 4.06 out of 5, close to the original Schematron 8B's 4.07 and ahead of the first-generation 3B's 3.91. On SimpleQA it scores 83.1, and Inference.net reports both V2 models beating DeepSeek V3.2 and GPT-5.4 Nano on that benchmark despite being much smaller. It targets web scraping, product data ingestion, financial document parsing, and search-augmented pipelines needing reliable structured output over long pages, with a 128K context window and 4,096-token output limit.
