GPT-4o

GPT-4o unifies language, vision, and audio in one model so conversations feel immediate and grounded. You can speak, type, or share images and screenshots; it parses the context, plans its steps, and answers in natural text or synthesized speech with round-trip times suited to live interactions. The model keeps long sessions coherent, follows instructions closely, and formats outputs as schema-true JSON when workflows require strict structure. It’s comfortable switching between chat, analysis, and code—explaining decisions as it goes, calling tools to search, run functions, or retrieve data, and tying responses back to what it “sees” in documents, charts, or UIs. Designed for production, GPT-4o streams tokens for responsive UX, supports function calling for agent stacks, and delivers strong cost-to-quality performance, making it a dependable default for multimodal copilots, customer support, developer assistants, and voice-first experiences.
