GPT-4o has been designed to provide quick responses to voice commands, with an average latency of 232 milliseconds. This is similar to the response time of human conversations and is a notable development for applications that require speed and responsiveness, like customer service chatbots or real-time transcription services.

Multimodal Capabilities

GPT-4o can process and generate text, audio, and image input and output combinations. This multimodal capability allows the AI to analyze and respond to various forms of data, enhancing its utility in diverse applications.

Language Support

GPT-4o supports multiple languages, including 50 languages, making it a versatile tool for global applications. This feature is particularly useful for real-time translation services, where instant and accurate translation can bridge communication gaps across different languages and cultures.

Emotional Expression and Tone

GPT-4o can pick up on emotion in a user’s voice and respond accordingly, making the interaction feel more natural and human-like. The AI can also express emotion through its own voice, such as sarcasm, bubbly tones, or singing.

Enhanced Performance and Accessibility

GPT-4o matches the performance of its predecessor, GPT-4 Turbo, in processing English text and code while showing marked improvements in understanding non-English languages. It outperforms existing models in vision and audio comprehension, all while being twice as fast, 50% more cost-effective, and supporting five times higher rate limits.

Limitations and Challenges

Despite these advancements, GPT-4o still has some limitations and challenges, including:

  • Social biases and hallucinations: GPT-4o can still exhibit social biases and sometimes generate false or nonsensical information. These limitations and challenges require continued research and refinement to ensure the accuracy, fairness, and reliability of AI-generated content.
  • Vulnerability to adversarial prompts: GPT-4o can be tricked into producing harmful or undesirable outputs by carefully crafted prompts.
  • Lack of fully integrated video capabilities: While GPT-4o has an integrated Voice Mode, the initial rollout does not include full real-time video capabilities.
  • Restricted access for free users: Free-tier ChatGPT users have limited access to GPT-4o, with a cap on the number of messages they can send.

But hey, OpenAI is actively working to address these limitations and further enhance GPT-4o’s capabilities. Planned features include integrating real-time video capabilities and an advanced voice mode to enable more natural, context-aware voice interactions. So we’re expecting bigger things than just voice integration.

Is it Free?

OpenAI typically provides both unpaid and paid options for their models. The unpaid version comes with usage restrictions, such as a set limit on daily prompts and interactions and potential limitations on available features.

For ChatGPT-4o, very much like the previous versions 3.5 and 4, OpenAI offers various pricing levels that generally consist of a basic free option and premium tiers, offering increased interactions and advanced capabilities. Please refer to the latest price plans below to find the most up-to-date pricing options suitable for your requirements.

The Voice Mode

This is the most mind-blowing feature of the latest release. It works by using text-to-speech technology and AI voices such as those from Resemble.AI, which involves separate models for transcribing audio to text, generating text output, and converting text back to audio.

But what makes GPT-4o so special? It can pick up on emotions in a user’s voice and respond accordingly, making the interaction feel more natural and human-like. The AI can also express emotion through its own voice, such as sarcasm, bubbly tones, or singing.

While GPT-4o can generate its own voice outputs, the initial rollout will feature a selection of preset voices to adhere to existing safety policies and ensure responsible use of the technology.

Use Cases for GPT-4o & AI Voices:

GPT-4o, OpenAI’s latest language model, can potentially stir up various applications across different industries. We already know how awesome this update is, but in what specific cases can we utilize this feature? Here are some of the potential applications of GPT-4o:

Conversational AI

GPT-4o’s advanced natural language processing capabilities are ideal for developing more intelligent and engaging conversational AI systems. The model’s ability to understand and respond to multimodal inputs, including text, audio, and images, allows for more natural and intuitive interactions.

GPT-4o is a good example. Callers can ask hands-free questions and get them answered promptly by simply dictating the necessary details before addressing concerns.

Virtual Assistants

AI is the rage in the virtual space. You can use GPT-4o to create virtual assistants that can handle a wide range of tasks, from scheduling appointments to providing personalized recommendations.

The multilingual support capability and real-time responsiveness make it suitable for global applications. Recently, telecommunications and airline companies have taken advantage of this feature, which allows companies with thousands of callers to reduce wait times.
