Explanation:

All statements are correct.

• Known as ‘AI agents’, GPT-4o and Project Astra have been touted as far superior to conventional voice assistants such as Alexa, Siri, and Google Assistant. 

• These are sophisticated AI systems that can engage in real-time, multi-modal (text, image, or voice) interactions with humans.

• Unlike conventional language models, which solely work on text-based inputs and outputs, AI agents can process and respond to a wide variety of inputs including voice, images, and even input from their surroundings.

• Also, language models do not have any autonomy since they only generate text output. AI agents, however, can perform complex tasks autonomously such as coding, data analysis, etc. When integrated with robotic systems, AI agents can even perform physical actions.

Hence option 3rd is correct.
