Overview

  • Free-tier ChatGPT users receive GPT-5 until usage caps switch them to GPT-5 Mini, while Plus and Pro subscribers retain unlimited full-model access.
  • Developers can access three API variants—GPT-5, GPT-5 Mini and GPT-5 Nano—to balance performance, cost and latency requirements.
  • A unified compute-routing system directs simple prompts to fast engines and complex queries to deeper reasoning without user intervention.
  • OpenAI’s new safe completions and test-time compute capabilities cut factual errors by up to 80%, delivering more reliable responses across coding, writing, health and finance tasks.
  • Early integrations with Microsoft 365 Copilot, GitHub Copilot and JetBrains tools have driven up to 2× gains in code quality and streamlined multi-step workflows in enterprise environments.
