GPT-4

By OpenAI
New Text Gen 4
Released: March 1, 2023

Overview

GPT-4 is OpenAI’s advanced multimodal model for strong reasoning, coding, and image-understanding. It supports long context, function and tool calling, and reliable JSON outputs, making it a solid default for RAG, agents, and enterprise copilots.

Description

GPT-4 improves on 3.5 with steadier logic, clearer instruction following, and better safety. It accepts text plus images, explains charts or screenshots, and grounds answers in the visual details it reads. For software work it maps specs to code, debugs, and refactors while keeping explanations concise. The API supports structured JSON, function calls, streaming, and retrieval integration, so teams can route queries to tools and return auditable results. In practice, GPT-4 serves as the heavy tier for complex analysis and policy-aware drafting, while smaller models handle routine prompts.GPT-4 improves on 3.5 with steadier logic, clearer instruction following, and better safety.
