OpenAI Introduces New o3 and o4-mini Reasoning Models

OpenAI just dropped two new AI models, o3 and o4-mini, the latest in its o-series built to think harder before answering. These are the smartest models the company has released so far, able to tap into ChatGPT's full toolkit to handle everything from web searches to image analysis.OpenAI o3 is our most powerful reasoning model that pushes the frontier across coding, math, science, visual perception, and more. It sets a new SOTA on benchmarks including Codeforces, SWE-bench (without building a custom model-specific scaffold), and MMMU. It's ideal for complex queries requiring multi-faceted analysis and whose answers may not be immediately obvious. It performs especially strongly at visual tasks like analyzing images, charts, and graphics. In evaluations by external experts, o3 makes 20 percent fewer major errors than OpenAI o1 on difficult, real-world tasks—especially excelling in areas like programming, business/consulting, and creative ideation. Early testers highlighted its analytical rigor as a thought partner and emphasized its ability to generate and critically evaluate novel hypotheses—particularly within biology, math, and engineering contexts.OpenAI o4-mini is a smaller model optimized for fast, cost-efficient reasoning—it achieves remarkable performance for its size and cost, particularly in math, coding, and visual tasks. It is the best-performing benchmarked model on AIME 2024 and 2025. In expert evaluations, it also outperforms its predecessor, o3‑mini, on non-STEM tasks as well as domains like data science. Thanks to its efficiency, o4-mini supports significantly higher usage limits than o3, making it a strong high-volume, high-throughput option for questions that benefit from reasoning.Continue ReadingSpotlight Deal:Apple M4 13-inch iPad Pro On Sale for $200 Off [Deal]Share Article:Facebook, Twitter, LinkedIn, Reddit, EmailFollow iClarified:Facebook, Twitter, LinkedIn, Newsletter, App Store, YouTube
