OpenAI, the San Francisco-based AI leader, released o3 and o4-mini on April 16, 2025, marking a significant leap in reasoning capabilities. Available to ChatGPT Plus, Pro, and Team users, these models can process blurry images, execute Python code, and perform web searches independently, outpacing predecessors like o1.
The flagship o3 model excels in coding, math, and science, scoring 99.5% on the AIME 2025 math competition with a Python interpreter. o4-mini, optimized for speed and cost, matches o3’s prowess in visual tasks while supporting higher usage limits. Both models integrate ChatGPT tools—web browsing, image generation, and code execution—for seamless multi-step problem-solving.
OpenAI’s Codex CLI, an open-source coding agent, enhances developer workflows by connecting o3 and o4-mini to local terminals, rivaling xAI’s Grok Studio. Posts on X praise o3’s coding finesse but note occasional instruction-following issues.
The launch, just days after GPT-4.1, underscores OpenAI’s rapid innovation, though some question its safety protocol transparency. These models position OpenAI as a frontrunner in agentic AI, challenging competitors like xAI’s collaborative-focused Grok Studio.
