# DeepSeek. 

Conversation and reasoning, with a separate API for developers

4.43 / 5    [Directory score](https://instain.ru/en/ai/deepseek/#editorial-rating) [Official website ](https://www.deepseek.com/)

DeepSeek develops its own models and provides an official chat and API. It suits text tasks, code explanations and solutions that require several steps.

## What DeepSeek is

DeepSeek is a model developer with its own user-facing and programmatic interfaces. Its official website links to the chat, developer platform and documentation. This helps distinguish the original service from sites and bots that use its name.

In a normal conversation, ask for a clear explanation of assumptions and a way to verify the result, rather than just a finished answer. For code, attach a minimal example and the expected behaviour. For text, specify the audience and facts that must remain.

## Reasoning and programming

The official API supports modes with reasoning and without it. Capabilities depend on the chosen model: you can not transfer the limitations of one version to the entire family. Model numbers and technical limits are better checked directly in the documentation.

Ask to parse the error in the program, compare the two approaches or turn the note into a plan. Then check the proposed solution: run the code and check the output with the source data. A convincing explanation does not confirm the correctness of the answer by itself.

## From Chat to Integration

For developers, DeepSeek describes API compatibility with common query formats. There is documentation on structured output, tool calls and integrations with agent environments. This simplifies the connection to the existing process, but does not replace the configuration of your own application.

Test a small use case and calculate actual costs first. Programmatic access is billed by usage, not by the number of open conversations in the consumer chat.

## Limitations and data

Answer quality depends on source context, language and the task. For current facts, consider which search tools are available; a model alone does not guarantee up-to-date information.

Before sending work material, review the service terms and permitted uses. Keep the API key under your control, never in a browser page’s public code.
