1. Meet o3-pro: OpenAI’s most advanced reasoning model yet On June 10, OpenAI quietly rolled out o3-pro, a new version of its o3 series focused on high-performance reasoning.

Based on OpenAI’s pricing page, o3-pro costs $20 per input and $80 for outputs, compared to o3 itself, which is now down to $2 and $8, a tenth of the price. A more comprehensive model ...

OpenAI launched o3-pro, a new version of its most advanced model aimed at delivering more reliable, thoughtful responses across complex tasks. Now available to Pro and Team users in ChatGPT and via AP ...

“OpenAI tells us outright that GPT-4o is the model that’s optimized for cost, and is good to use for most tasks, while their reasoning models like o3-pro are more suited for coding or specific ...

Additionally, Pro and Team users can now use o3-pro in ChatGPT. The pricing for using o3-pro in the API will be 87% cheaper than o1-pro, and the price of o3 is also being cut by 80%.

OpenAI is planning to ship an update to ChatGPT that will turn on the new o3 Pro model, which has more compute to think harder. ChatGPT currently offers o4-mini, o4-mini-high, GPT-4.5, GPT-4.1 ...

The new version, dubbed DeepSeek-R1-0528, is now being positioned as a direct challenger to OpenAI’s o3 and Google’s Gemini 2.5 Pro, with benchmark results and technical enhancements that show ...

While OpenAI rival models like Gemini 2.5 Pro complied with the instruction, o3 rebelled and edited the shutdown file to say "Shutdown skipped" instead.

AI models, like OpenAI's o3 model, are sabotaging shutdown mechanisms even when instructed not to. Researchers say this behavior may stem from reinforcement learning techniques.
