🔥 DeepSeek V4 Pro is Out! And GPT, Claude & Gemini Now ALL Have a New Problem

DeepSeek V4 Pro just entered the AI race with powerful new capabilities that could challenge GPT, Claude, and Gemini. So how to use it now?

TL;DR

DeepSeek V4 Pro and Grok 4.6 both offer performance close to frontier models at much lower API prices. Your best choice depends on the workload, not the leaderboard.

Grok 4.6 fits coding and agent workflows well, especially inside Cursor. DeepSeek V4 Pro makes more sense when you care about lower API cost, long context, automation, terminal work, or cybersecurity.

Real user tests also show that token usage and agent setup can change the final cost a lot. You should test both models on the same task before moving a production workflow.

Key points

  • Grok 4.6 reaches 61 on the AA Intelligence Index, matching GPT-5.6 Sol Max.

  • DeepSeek V4 Pro offers lower API pricing and a 1M-token context window.

  • Real-world agent tests show that benchmark scores alone don’t predict total cost or workflow quality.

Introduction

I’m a big Claude fan, but I have to admit that DeepSeek has one advantage that Claude still doesn’t fully offer: open access and extremely low cost.

That’s why many said DeepSeek release to a “ChatGPT moment.” Whenever DeepSeek launches a new model, it gets serious attention.

The latest model is DeepSeek V4 Pro.

It pushes long-context processing further while keeping costs dramatically lower. It’s open-source, and its off-peak pricing can be up to 50% cheaper.

I’ll go straight into performance, pricing, use cases, and a few real tests to see if it really deserves the hype.
