From TechCrunch: OpenAI announced on Wednesday the launch of o3 and o4-mini, new AI reasoning models designed to pause and work through questions before responding.
The company calls o3 its most advanced reasoning model ever, outperforming the company’s previous models on tests measuring math, coding, reasoning, science, and visual understanding capabilities. Meanwhile, o4-mini offers what OpenAI says is a competitive trade-off between price, speed, and performance — three factors developers often consider when choosing an AI model to power their applications.
Unlike previous reasoning models, o3 and o4-mini can generate responses using tools in ChatGPT such as web browsing, Python code execution, image processing, and image generation. Starting today, the models, plus a variant of o4-mini called “o4-mini-high” that spends more time crafting answers to improve its reliability, are available for subscribers to OpenAI’s Pro, Plus, and Team plans.
The new models are part of OpenAI’s effort to beat out Google, Meta, xAI, Anthropic, and DeepSeek in the cutthroat global AI race. While OpenAI was first to release an AI reasoning model, o1, competitors quickly followed with versions of their own that match or exceed the performance of OpenAI’s lineup. In fact, reasoning models have begun to dominate the field as AI labs look to eke more performance out of their systems.
