1. Launch of GPT-4o: Multimodal AI Goes Mainstream
In 2024, OpenAI introduced GPT-4o — a groundbreaking multimodal model that combines text, image, and audio processing. But 2025 saw this model becoming fully integrated into daily workflows.
Key Highlights:
- Real-time voice interaction (like having a natural conversation with an assistant).
- Instant image interpretation, including charts, UIs, and handwriting.
- Integration with desktop and mobile devices via ChatGPT apps and browser extensions.
“With GPT-4o, AI isn’t just smarter — it’s more human.” – Sam Altman, CEO of OpenAI
2. Strategic Partnership with Apple and Microsoft
One of the most headline-grabbing moves was OpenAI’s deepening ties with Apple and Microsoft.
Apple:
- GPT-4o is now integrated into iOS 18, macOS Sequoia, and Siri.
- Users can access ChatGPT via a system-level experience on iPhones and Macs.
Microsoft:
- GPT-4 is now the default AI behind Copilot in Windows, Word, Excel, and Outlook.
- Azure OpenAI Service continues to drive enterprise-grade AI deployments.
This strategic move signals the mainstream adoption of AI at the OS level, not just as a separate app.
3. Custom GPTs: AI Personalization at Scale
OpenAI now allows users to create their own GPTs using a simple, no-code interface. Think of it like building a chatbot tailored to your brand, workflow, or audience.
Use Cases:
- Educators building AI tutors for students.

As of August 2025, there are over 1.8 million custom GPTs in use globally.
