DeepSeek V4 Pro 0423
About this model
DeepSeek V4 Pro 0423 is an AI model from DeepSeek, made available through the API on April 24, 2026. It can read up to 1,048,576 tokens in one request, roughly 1,966 pages of text, and write up to 384,000 tokens in a single answer.
Through the API it costs $0.96 per million input tokens and $1.91 per million output tokens. Its pricing sits in the middle of the market.
It supports extended reasoning: it can "think" step by step before answering, which helps on maths, code and complex questions. It can call tools and functions, so developers can connect it to search, databases or other software. Its weights are openly published (deepseek-ai/DeepSeek-V4-Pro), so it can also be downloaded and run on your own hardware.
