OpenAI kicked off a 12-day public relations event on December 5, 2024, unveiling a new product or feature each day to showcase its advancements in AI technology.

The event began with the full release of the o1 model, which operates faster and reduces errors by 34% on complex questions, available to ChatGPT Plus and Team subscribers.

On the fifth day, ChatGPT was integrated with Apple Intelligence, allowing users to access its features directly on Apple devices.

The second day introduced Reinforcement Fine-Tuning (RFT), enabling developers to customize AI models using reinforcement learning for specific tasks.

By day seven, OpenAI launched a Projects feature, allowing users to organize conversations and files related to specific tasks.

Day six saw the introduction of new voice capabilities for ChatGPT, including video calling and a seasonal Santa voice preset, with some features set to launch in early January.

On day four, OpenAI officially released Canvas, a feature designed for extended writing and coding projects, now available to all ChatGPT users.

OpenAI also introduced ChatGPT Pro, a $200 subscription that provides unlimited access to advanced features, alongside a grant program for medical researchers.

The timing of the event coincided with competing releases from Google, underscoring the intense competition in AI development as both companies made rapid announcements.

By day eight, ChatGPT's search capabilities expanded to all users, enhancing its functionality to operate more like a web search engine.

On the tenth day, OpenAI launched a toll-free number for voice and messaging access to ChatGPT, targeting users without stable internet access.
