OpenAI o3 is the most advanced reasoning model from OpenAI, purpose-built for handling complex, high-cognition tasks. Launched in April 2025, it delivers exceptional performance in software engineering, mathematics, and scientific problem-solving. The model introduces three levels of reasoning effort—low, medium, and high—allowing users to balance between latency and depth of reasoning based on task complexity. o3 supports essential tools for developers, including function calling, structured outputs, and system-level messaging. With built-in vision capabilities, o3 can interpret and analyze images, making it suitable for multimodal applications. It’s available through Chat Completions API, Assistants API, and Batch API for flexible integration into enterprise and research workflows.
Gemini 2.0 Flash Thinking is an advanced reasoning model designed to enhance performance and explainability by making its thought process visible. It excels in complex problem-solving, coding challenges, and mathematical reasoning, demonstrating step-by-step solutions. Optimized for tasks that demand detailed explanations and logical analysis, the model also features native tool integration, including code execution and Google Search capabilities.
