About DeepSeek V4 Guide

What this site is

DeepSeek V4 Guide is a step-by-step tutorial site covering the DeepSeek V4 family: what the models are, how to access them through the official API and third-party tools, what they cost, how they benchmark, and how to run them locally. We focus on practical, usable answers — API setup, pricing math, agent integration, and local deployment — written as complete walkthroughs rather than marketing summaries.

Who this site is for

We write for two distinct audiences, and every guide is tagged so you know which one it serves:

• BEGINNER — people who do not yet know the model names, let alone how APIs work. If you have never used a large language model, start with the beginner guide.
• DEVELOPER — engineers who already know what an API key is and want exact base URLs, environment variables, model slugs, and code samples. See API setup or IDE integration.

How we research

Each guide is assembled from primary sources — the official DeepSeek API documentation, the arXiv technical report, official model cards on Hugging Face, and release changelogs — cross-checked against independent analysis where available. Every factual claim carries a numbered citation that links to the reference at the bottom of the page, so you can verify it yourself.

• Prices, model specs, and benchmark scores are labeled with their as-of date and marked when vendor-reported.
• We do not fabricate numbers. Unverified claims are either flagged as reported/rumor or omitted.
• We link out to the source rather than paraphrasing it into an unverifiable claim.

What is inside a guide

Every guide follows the same structure: an overview box that answers the question in one paragraph, numbered steps that walk through the actual process, tables for specs and pricing where numbers matter, code blocks you can copy, honest notes about pitfalls, and a references list with the sources used. Guides cross-link to each other so you can follow a topic end to end — for example from pricing to running the model locally.

Independence
