On April 15, 2025, OpenAI announced the launch of GPT-4o, the latest iteration of its generative model series. Unlike previous versions, GPT-4o is optimized for real-time interaction and multimodal inputs (text, image, audio, video).
This is a game-changer for developers building tools for virtual assistants, customer support, OCR applications, and creative generation.
What’s New Technically?
- Real-Time Latency: GPT-4o dramatically reduces response time to ~200ms for voice, enabling fluid conversation.
- Multimodal Capabilities: You can feed it text, images, and audio, and it will interpret and respond accordingly.
- Smaller Footprint, Better Performance: It matches or exceeds GPT-4-Turbo while being cheaper and more efficient to run.
Developer Implications
- Voice-driven interfaces become viable with much lower latency.
- Enhanced OCR/image parsing by directly feeding visual input and getting structured data.
- You can build cross-modal applications—e.g., describe an image and ask questions about it in real-time.
How to Use It
from openai import OpenAI
client = OpenAI(api_key=”your_key”)
response = client.chat.completions.create(
model=”gpt-4o”,
messages=[{“role”: “user”, “content”: “Describe the image I uploaded.”}],
files=[“your_image.jpg”]
)
