BEIJING: Chinese internet search giant Baidu released a new artificial intelligence reasoning model Sunday and made its AI chatbot services free to consumers as ferocious competition grips the sector.

Technology companies in China have been scrambling to release improved AI platforms since start-up DeepSeek shocked its rivals with its open source and highly cost-efficient model in January.

In a post on WeChat, Baidu announced the launch of its latest X1 reasoning model – which the company claims performs similarly to DeepSeek's but for lower cost – and a new foundation model, Ernie 4.5.

Baidu also made its AI chatbot Ernie Bot free for individual users more than two weeks ahead of schedule. Previously, users had to pay a subscription to access the company's latest AI models via Ernie Bot.

Ernie 4.5 "outperforms" US-based OpenAI's GPT-4.5 model in "multiple benchmarks", while Ernie X1 features "enhanced capabilities in understanding, planning, reflection, and evolution", Baidu said.

The Beijing-based company was one of China's first to roll out a generative AI platform publicly, in 2023, but rival chatbots from companies such as TikTok owner ByteDance and Moonshot AI have since gained more users.
