Deep Architectural Overview

GPT-4o (“o” for “omni”) represents OpenAI’s unified multimodal flagship. It accepts text and vision inputs, generates structured outputs with 100% schema compliance, and matches GPT-4 Turbo intelligence with 2x faster token generation.

Strengths & Considerations

Core Strengths
  • 2x faster generation than GPT-4 Turbo
  • 50% cheaper token cost
  • Strict JSON schema structured output compliance
Known Limitations
  • Complex multi-step Olympiad logic surpassed by o-series reasoning models
