After the release of DeepSeek R1, a Chinese-made freely available and open source "reasoning" AI model, the creators of ChatGPT have fully released o3-mini to all paid tiers, including a trial to free users, the company said in a press release on Friday.

On the heels of DeepSeek R1, the latest model from OpenAI promises more advanced capabilities at a cheaper price.

While DeepSeek can point to common benchmark results and Chatbot Arena leaderboard to prove the competitiveness of its model, there's nothing like direct use cases to get a feel for just how useful a new model is.

OpenAI released its newest reasoning model, called o3-mini, on Friday. OpenAI says the model delivers more intelligence than OpenAI’s first small reasoning model, o1-mini, while maintaining o1-mini’s low price and speed. The company says o3-mini excels in science, math, and coding problems.

OpenAI has launched a new 'reasoning' AI model, o3-mini, the successor to the AI startup's o1 family of reasoning models.

Thanks to DeepSeek, OpenAI has released its frontier o3-mini model for free to all ChatGPT users. ChatGPT Plus users get the o3-mini-high model.

DeepSeek is a Chinese artificial intelligence provider that develops open-source LLMs. R1, the latest addition to the company’s model lineup, debuted last week. The release of the LLM caused a broad selloff in AI stocks that sent Nvidia Corp.’s shares plummeting 17% on Monday, along with many other technology stocks.
