About
GPT-4o is OpenAI's most advanced model to date. This multimodal model handles both text and image inputs while generating text outputs. Matching the intelligence of GPT-4 Turbo, it is remarkably more efficient, delivering text at twice the speed and at half the cost. Additionally, GPT-4o exhibits the highest vision performance and excels in non-English languages compared to previous OpenAI models.
