The GPT-4 series represents OpenAI's flagship conversational models. GPT-4o ("omni") is the multimodal variant that handles text, images, and audio natively. GPT-4.1 brings improved instruction following and coding performance. These models offer the best balance of capability and cost for general-purpose tasks.
The o1 and o3 models use chain-of-thought reasoning to "think" before responding. They excel at math, science, complex coding, and multi-step logic problems. o3-pro offers the highest reasoning quality at a premium price, while o3-mini provides reasoning capabilities at lower cost.
GPT-4o Mini is OpenAI's cost-optimized model, delivering strong performance at a fraction of the price of full GPT-4o. It supports vision, function calling, and JSON mode, making it ideal for high-volume production workloads where cost efficiency matters more than peak capability.
All OpenAI models are accessible through the OpenAI API. Rate limits scale with usage tier (free, tier 1--5). Enterprise customers get higher throughput. Batch API offers 50% discounts for non-urgent workloads processed within a 24-hour window.
OpenAI offers over 60 AI models through their API, including GPT-4o, GPT-4o Mini, o3, DALL-E 3, Whisper, and text embedding models. The lineup covers language, vision, image generation, and speech capabilities.
GPT-4o is OpenAI's flagship model, excelling at general-purpose tasks. For reasoning, o3 leads. For cost efficiency, GPT-4o Mini offers strong performance at a fraction of the cost. Rankings change frequently with new releases.
OpenAI pricing ranges from $0.15/M tokens (GPT-4o Mini input) to $60/M tokens (o3 output). Most developers start with GPT-4o at $2.50/M input tokens, which offers the best balance of quality and cost.
