What is DeepSeek V4 Pro 0813 good for?

DeepSeek V4 Pro 0813 comes from DeepSeek; in uttapen you reach it with the model id "deepseek/deepseek-v4-pro-0813". It accepts up to 1,048,576 tokens of input per call, so a long document or several source files fit in a single request. A single response can run to 943,718 tokens. On price it sits in the "mid-range" band — cheaper than 130 and dearer than 268 of the other paid models in the catalogue.

What you get on top of text in, text out: 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.

Input runs at 35,661 toman per 1M tokens and output at 1,422,962 — output costs 39.9× input, so trimming the answer saves more than trimming the prompt. It supports cached input: repeated context is billed at 33,929 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 GPT-3.5 Turbo 16k: DeepSeek V4 Pro 0813 works out about 41% 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 53 thousand-word requests on DeepSeek V4 Pro 0813, and every 1,000 toman is about 527 words of round trip. A job with one million input tokens and one million output tokens comes to 1,458,622 toman in total. Filling this model's 1,048,576-token window costs 37,393 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-v4-pro", and choosing between those two is where most people hesitate. Both land at nearly the same price on a thousand-word request (1,896 and 2,160 toman). Maximum answer length differs as well: 943,718 against 393,216 tokens. On parameters the other takes max_completion_tokens.

DeepSeek has 18 models in our catalogue; the cheapest is DeepSeek V4 Flash 0423 at 123 toman per thousand words and the dearest DeepSeek Pro Latest at 3,642. Among the less common parameters it accepts logit_bias, logprobs, min_p, presence_penalty, reasoning_effort, repetition_penalty — all through the standard request body. By context size the nearest option from another provider is Ember-1 at 1,048,576 tokens.

Where it makes sense: product chatbots and internal assistants, where cost and quality have to balance, 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.
