What is Schematron V2 Small good for?

Schematron V2 Small comes from Inference Net; in uttapen you reach it with the model id "inference-net/schematron-v2-small". It accepts up to 128,000 tokens of input per call, so a long document or several source files fit in a single request. A single response can run to 4,096 tokens. On price it sits in the "very cheap" band — cheaper than 350 and dearer than 47 of the other paid models in the catalogue.

Capabilities available on this id: it returns schema-valid JSON through response_format, ready to hand to your code. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper.

For a back-of-envelope figure: about 126 toman per 1,000-word exchange (17,311 in, 79,630 out, per 1M tokens). It supports cached input: repeated context is billed at 17,311 toman per 1M, which matters a lot if your system prompt is long. You are always charged for the usage the request actually reported, never for the estimate, and a failed request costs nothing.

The closest alternative with the same capabilities from a different provider is Llama 3.2 1B Instruct: Schematron V2 Small works out about 20% more expensive, and its context window is larger. Both run on the same key and the same code, so trying the other one is a single string change.

To make the figure concrete: 100,000 toman of credit buys roughly 794 thousand-word requests on Schematron V2 Small, and every 1,000 toman is about 7,937 words of round trip. A job with one million input tokens and one million output tokens comes to 96,941 toman in total. Filling this model's 128,000-token window costs 2,216 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "inference-net/schematron-v2-turbo", and choosing between those two is where most people hesitate. On a thousand-word request this variant works out about 60% more expensive (126 against 81 toman). Maximum answer length differs as well: 4,096 against 8,192 tokens.

Inference Net has 2 models in our catalogue; the cheapest is Schematron V2 Turbo at 81 toman per thousand words and the dearest Schematron V2 Small at 126. Among the less common parameters it accepts logit_bias, min_p, presence_penalty, repetition_penalty, top_k — all through the standard request body. It does not support include_reasoning, reasoning, tool_choice, tools, which most models here do, so test before switching if your code relies on them. By context size the nearest option from another provider is Nova Micro 1.0 at 128,000 tokens.

What to use it for: high-volume work such as classification, tagging and bulk summarising, extracting data against a fixed schema.
