## Definition

DeepSeek V4 Pro is the premium tier of DeepSeek's V4 series: a 1.6-trillion-parameter, 49-billion-active Mixture-of-Experts model with a 1-million-token context window. It is the largest open-weight model released as of April 2026, MIT-licensed, and directly competitive with closed-source frontier models on coding benchmarks.

Released on [April 24, 2026](https://api-docs.deepseek.com/news/news260424), V4 Pro introduces a tunable `reasoning_effort` parameter (low/high/max) and a "Think Max" mode that scales reasoning tokens for complex tasks, priced at $1.74 input / $3.48 output per million tokens — roughly one-sixth the cost of Claude Opus 4.7 and one-seventh of GPT-5.5.

## Analogy

Think of it as a factory-floor industrial robot priced like a power drill.

## Why it's emerging now

DeepSeek shipped V4 Pro on April 24, 2026 — the largest open-weight model to date, with a 1M-token context window and pricing that undercuts every closed-source competitor by 6-7x. Its `reasoning_effort` parameter and Think Max mode make it the first open-weight model with dial-up reasoning intensity, directly competing with Claude Opus 4.7 and GPT-5.4 on agentic coding tasks.
