DeepSeek
China·China
A Chinese AI model developer. It stunned the world by building top-tier models at a fraction of the cost, and it releases its model weights in full. Its flagship model is DeepSeek-V4-Pro. Officially launched in August 2026, V4-Pro comes with a feature that lets users adjust reasoning intensity across three levels. That same month, OpenAI and Anthropic rolled out lower-priced new products, a move widely seen as a response to the wave of cheap Chinese models. Meanwhile, a jailbreak prompt originally made for Google's Gemma was reported in August 2026 to also work on DeepSeek V4 Flash, and around the same time, the DeepSeek-V4-Flash-0731 model was flagged for freezing during long-context tasks.
