DeepSeek V3 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
import json

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

schema = {
    "name": "ticket",

What is DeepSeek V3 good for?

DeepSeek publishes this model; we expose it under the id "deepseek/deepseek-chat". Its context window is 163,840 tokens, roughly 123k English words in one request. A single response can run to 16,000 tokens. On price it sits in the "cheap" band — cheaper than 247 and dearer than 150 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. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper.

Pricing is 89,117 toman per 1M input tokens and 356,156 per 1M output tokens. A 1,000-word round trip on DeepSeek V3 lands near 579 toman. 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 MiniMax M2, and DeepSeek V3 costs about the same, and its context window is smaller. 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 173 thousand-word requests on DeepSeek V3, and every 1,000 toman is about 1,727 words of round trip. A job with one million input tokens and one million output tokens comes to 445,273 toman in total. Filling this model's 163,840-token window costs 14,601 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "deepseek/deepseek-chat-v3-0324", and choosing between those two is where most people hesitate. Both land at nearly the same price on a thousand-word request (579 and 644 toman). Maximum answer length differs as well: 16,000 against 115,200 tokens. On parameters, this one takes logit_bias, min_p, presence_penalty, repetition_penalty while the other takes logprobs, top_logprobs.

DeepSeek has 18 models in our catalogue; the cheapest is DeepSeek V4.1 Flash (batch) at 90 toman per thousand words and the dearest DeepSeek Pro Latest at 3,647. 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, 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 Llama Guard 4 12B at 163,840 tokens.

Good fits: high-volume work such as classification, tagging and bulk summarising, agents that reach out to APIs and databases, extracting data against a fixed schema.
