The Rise of Multimodal Interactive AI Assistants

Let’s dive into the details of ChatGPT-4o and Astra, two leading groundbreaking technologies in this new era of multimodal interactive AI agents.


GPT-4o (“o” for “omni”) is a multimodal interactive AI system developed by OpenAI.  Unlike its predecessor, ChatGPT, which is a text-only interactive AI system, GPT-4o accepts and generates combinations of text, audio, images, and video. In contrast to ChatGPT, which relies on separate models to handle different modalities—resulting in a loss of contextual information such as tone, multiple speakers, and background noises—GPT-4o processes all these modalities using a single model. This unified approach allows GPT-4o to maintain the richness of the input information and produce more coherent and contextually aware responses.

GPT-4o mimics human-like verbal responses, enabling real-time interactions, diverse voice generation, and instant translation. It processes audio inputs in just 232 milliseconds, with an average response time of 320 milliseconds—comparable to human conversation times. Moreover, GPT-4o includes vision capabilities, enabling it to analyze and discuss visual content such as images and videos shared by users, extending its functionality beyond text-based communication.


Astra is a multimodal AI agent developed by Google DeepMind with the goal of creating an all-purpose AI that can assist humans beyond simple information retrieval. Astra utilizes various types of inputs to seamlessly interact with the physical world, providing a more intuitive and natural user experience. Whether typing a query, speaking a command, showing a picture, or making a gesture, Astra can comprehend and respond efficiently.

Astra is based on its predecessor, Gemini, a large multimodal model designed to work with text, images, audio, video, and code. The Gemini model, known for its dual-core design, combines two distinct but complementary neural network architectures. This allows the model to leverage the strengths of each architecture, resulting in superior performance and versatility.

Astra uses an advanced version of Gemini, trained with even larger amounts of data. This upgrade enhances its ability to handle extensive documents and videos and maintain longer, more complex conversations. The result is a powerful AI assistant capable of providing rich, contextually aware interactions across various mediums.
