DeepSeek closes gap with ChatGPT, Gemini in AI race with R1 upgrade: Cuts hallucinations and improves reasoning

Chinese artificial intelligence firm DeepSeek has introduced an upgraded version of its R1 model, claiming significant improvements in mathematical reasoning, programming, and logical capabilities, while reducing hallucination rates, a common flaw in large language models.

The company revealed details of the new model, DeepSeek-R1-0528, on Thursday via the AI platform Hugging Face, stating that its performance now closely rivals top-tier models such as OpenAI’s o3 and Google’s Gemini 2.5 Pro. The announcement comes as part of China’s ongoing efforts to position itself as a serious contender in the global AI race.
