OpenAI has launched its most powerful reasoning models, o3 and o4-mini, supporting “image-based thinking” and multimodal reasoning.

OpenAI has released the latest full-strength versions of the o3 and o4-mini models, which are currently the most intelligent iterations. These models come with comprehensive tool access capabilities. The o3 is the most powerful reasoning model, excelling in multi-domain tasks such as programming, mathematics, science, and visual perception. It performs exceptionally well in visual tasks, capable of analyzing images, charts, and more, while providing accurate answers to complex queries. The o4-mini is known for its fast and efficient inference capabilities, making it ideal for high-throughput tasks.
