deepseek

Overview

DeepSeek is an AI platform developed by DeepSeek that gained global attention for delivering advanced reasoning, coding, mathematics, and problem-solving capabilities while operating at a significantly lower cost than many competing AI systems. Its models have emerged as strong competitors to leading Western AI platforms, particularly among technical users and developers.

Recent Updates

Key takeaway: On August 13, 2026, DeepSeek released V4-Pro, its flagship model, across the DeepSeek app, web, and API. New peak and off-peak API pricing took effect on August 16, 2026, with peak rates of $1.32 per million input tokens and $3.96 per million output tokens.

V4-Pro is DeepSeek’s most advanced publicly available model and represents a significant step up from earlier DeepSeek releases in reasoning and coding work. The pricing change is notable because DeepSeek built its reputation partly on unusually low API costs. Under the new structure, off-peak rates are $0.66 per million input tokens and $1.98 per million output tokens, while peak rates are $1.32 and $3.96 respectively. For developers and students who rely on DeepSeek’s API, the change means budgeting for higher usage costs, especially during peak hours.
