OpenAI has released GPT-4o, an advanced AI model building on GPT-4, with improved text, audio, and vision capabilities.

GPT-4o offers significantly faster response times, better language support, and is more cost-effective than its predecessors.

The new model introduces emotive styles and tones in responses, aiming for more human-like interactions.

OpenAI breaks from tradition by offering GPT-4o for free to all users, with gradual capability rollouts starting with text and image functions.

Usage of GPT-4o by free users is subject to rate limits, with automatic fallback to GPT-3.5 when exceeded.

Tech giants like Apple and Google are exploring AI features similar to GPT-4o, marking a trend towards generative AI in the industry.

Microsoft plans to incorporate GPT-4o into its products, potentially affecting competition with Google, Meta, and Apple.

While GPT-4o has limitations that OpenAI is working on, its rollout includes preset voice options for audio outputs within safety guidelines.

OpenAI has also launched a ChatGPT desktop app for macOS, with a Windows version slated for later this year, both supporting GPT-4o.
