Ling 3.0 Flash example: JSON output against a schema

The example is picked from this model's own capabilities. Drop in your key and it runs as is.

from openai import OpenAI

client = OpenAI(base_url="https://api.uttapen.ir/v1", api_key="sk-up-…")

What is Ling 3.0 Flash good for?

Ling 3.0 Flash is one of inclusionAI's models. Put "inclusionai/ling-3.0-flash" in the model field and the rest of your code stays as it is. Ling 3.0 Flash keeps 262,144 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 32,768 tokens. On price it sits in the "very cheap" band — cheaper than 390 and dearer than 8 of the other paid models in the catalogue.

What it can do beyond plain text: it supports tool calling, so it can invoke your own functions with valid arguments; it returns schema-valid JSON through response_format, ready to hand to your code; it has a reasoning mode that pays off on multi-step problems, maths and debugging. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper. Keep in mind that reasoning tokens are output tokens and do appear on the bill.

Pricing is 7,271 toman per 1M input tokens and 21,812 per 1M output tokens. A 1,000-word round trip on Ling 3.0 Flash lands near 38 toman. It supports cached input: repeated context is billed at 1,454 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 3.1 8B Instruct: Ling 3.0 Flash works out about 38% cheaper, 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 2,632 thousand-word requests on Ling 3.0 Flash, and every 1,000 toman is about 26,316 words of round trip. A job with one million input tokens and one million output tokens comes to 29,082 toman in total. Filling this model's 262,144-token window costs 1,906 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "inclusionai/ling-3.0-tiny", and choosing between those two is where most people hesitate. On a thousand-word request this variant works out about 40% more expensive (38 against 27 toman). Maximum answer length differs as well: 32,768 against 250,000 tokens. On parameters, this one takes logit_bias, min_p, repetition_penalty, top_k while the other takes structured_outputs.

inclusionAI has 4 models in our catalogue; the cheapest is Ling 3.0 Tiny at 27 toman per thousand words and the dearest Ling 3.1 Flash at 135. Among the less common parameters it accepts logit_bias, logprobs, min_p, presence_penalty, repetition_penalty, top_k — all through the standard request body. It does not support structured_outputs, 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 Aion 3.5 at 262,144 tokens.

Good fits: high-volume work such as classification, tagging and bulk summarising, logic puzzles and code review, agents that reach out to APIs and databases, extracting data against a fixed schema, analysing a long document or codebase in one request.
