OpenAI has just unveiled its latest breakthroughs in artificial intelligence with the release of the o3 and o4-mini models. These new models represent a significant leap forward in reasoning capabilities, equipped with full agentic access to all ChatGPT tools and the groundbreaking ability to "think with images." Alongside these models, OpenAI has also launched an open-source coding agent, Codex CLI, further expanding the horizons of AI-driven problem-solving.
The o3 model is OpenAI's new flagship reasoner, setting new standards for state-of-the-art (SOTA) performance across a variety of domains including coding, mathematics, science, and multimodal benchmarks. With its advanced reasoning capabilities, o3 is designed to tackle complex problems with unprecedented accuracy and efficiency.
For those seeking a more cost-effective solution without compromising on performance, the o4-mini model offers fast and efficient reasoning. This model significantly outperforms previous mini models and even saturates benchmarks like the AIME 2025 math competition.
In addition to the new reasoning models, OpenAI has launched Codex CLI, an open-source coding agent that runs directly in users' terminals. This agent links reasoning models with coding tasks, providing a seamless integration of AI-driven reasoning and practical coding solutions.
The release of o3, o4-mini, and Codex CLI marks a significant milestone in the evolution of AI reasoning. These models not only push the boundaries of what AI can achieve but also bring us closer to the concept of Artificial General Intelligence (AGI). With their ability to think with images, access a wide range of tools, and produce novel scientific ideas, these models are setting new benchmarks for the future of AI.
As we continue to explore the capabilities of these advanced models, one thing is clear: the future of AI is here, and it's more powerful and versatile than ever before.
o3 is OpenAI's top-tier reasoner, offering the highest performance across various benchmarks, while o4-mini provides fast and cost-efficient reasoning, making it a more affordable option without compromising on capabilities.
Yes, both o3 and o4-mini are the first models to integrate visual analysis and manipulation directly into their reasoning process, allowing them to "think with images."
Codex CLI is an open-source coding agent that runs in users' terminals, linking reasoning models with coding tasks to enhance productivity and efficiency.
Both o3 and o4-mini have full agentic access to all ChatGPT tools, including web search, Python, and image generation, which they can use and combine to enhance their problem-solving process.
These models represent a qualitative leap in AI reasoning, pushing the boundaries of what AI can achieve and bringing us closer to the concept of AGI. They are capable of producing novel scientific ideas and setting new benchmarks for future AI developments.
