What Are AI Chatbots and Why They Matter

AI chatbots are digital assistants powered by Large Language Models (LLMs) capable of understanding and generating human-like language. From streamlining support desks to assisting with content creation and real-time decision-making, AI chatbots help teams scale operations without compromising on experience.

Choosing the right chatbot engine determines how effective your bot is at tasks like code suggestions, customer engagement, or multilingual responses. MSG91’s Agentic AI lets you mix-and-match LLMs for use cases that best suit your business logic.

Verdict: Which One to Choose?

If your primary focus is bot building, here’s how to decide:

• Use ChatGPT for dynamic, multi-turn conversations and empathetic responses.
• Go with Gemini when you need bots to reference real-time data or offer localized language support.
