Recently, headlines across the globe have been dominated by news about ChatGPT. That's hardly surprising. It's only been two years since OpenAI introduced its AI chatbot, and it's become indispensable for many. This chatbot has completely changed the game for artificial intelligence, showing that machines can indeed grasp the complexities of human language and interaction. So, any update to the system is a big deal, impacting various sectors including markets.

On Monday, OpenAI rolled out a new AI model called GPT-4o. This update brings GPT-4 to everyone, including OpenAI’s free users. The new model is "much faster" and boasts enhanced capabilities in text, video, and audio. OpenAI also mentioned plans to eventually enable users to video chat with ChatGPT.

The "o" in GPT-4o stands for omni. This new model empowers ChatGPT to handle 50 different languages with improved speed and quality. Moreover, it's accessible via OpenAI’s API, allowing developers to start building applications with the new model immediately.

During an event on Monday, OpenAI’s CTO Mira Murati also announced the launch of the ChatGPT desktop app.

Microsoft is OpenAI's largest stakeholder, having invested over $13 billion. Despite this, OpenAI's new ChatGPT app for computers has debuted on Apple's Macs first. The Windows version is anticipated later this year, though an exact timeline hasn't been provided by OpenAI yet.

The app sports a revamped user interface and enables users to ask ChatGPT questions about their screen content, either by typing or speaking. The AI then furnishes responses based on the visual input.

Regarding Apple, the company is closing in on an agreement with OpenAI to integrate the startup’s technology into the iPhone. Negotiations for incorporating ChatGPT features into Apple’s iOS 18, the forthcoming iPhone operating system, are nearing completion. Apple intends to make a splash in the AI realm in June during its annual Worldwide Developers Conference, a move that might impact the Apple stock price.

OpenAI’s recent strides have spurred discussions about the company’s potential to challenge Google Search, Alphabet Inc.’s flagship product.

However, not everyone is sold on OpenAI’s capabilities. Tesla Inc. CEO and ex AI founder Elon Musk expressed doubts about OpenAI’s latest AI model development. Earlier this year, Musk filed a lawsuit against OpenAI, claiming that the company has deviated from its initial mission of creating AI for the betterment of humanity. He demands that the court compel the company to disclose its research and technologies and prohibit the use of OpenAI's resources to generate profits in partnership with Microsoft.

Following the unveiling of GPT-4o, Musk downplayed the announcement, suggesting that the AI’s capabilities weren't as groundbreaking as claimed.
