GPT-4

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.
