The OpenAI o3-mini is a high-speed, cost-effective reasoning model designed for STEM applications, with strong performance in science, mathematics, and coding. Launched in January 2025, it includes essential developer features such as function calling, structured outputs, and developer messages. The model offers three reasoning effort levels—low, medium, and high—allowing users to optimize between deeper analysis and faster response times. Unlike the o3 model, it lacks vision capabilities. Initially available to select developers in API usage tiers 3-5, it can be accessed via the Chat Completions API, Assistants API, and Batch API.
Gemini 2.0 Flash is Google's high-performance, low-latency model designed to drive advanced agentic experiences. Equipped with native tool integration, it supports multimodal inputs, including text, images, video, and audio. Offering substantial improvements over previous versions, the model balances efficiency, speed, and enhanced capabilities for seamless real-time interactions.
