AI chatbots use natural language processing (NLP) and machine learning (ML) algorithms to understand and respond to user inputs conversationally. When a user types a query or message, the chatbot processes the input, identifies the intent, and extracts relevant information or keywords. It then uses pre-trained language models, such as GPT, to generate contextually appropriate and coherent responses. 

The chatbot can also access specific databases or knowledge bases to provide accurate and tailored information. Over time, AI chatbots improve their understanding and performance, making them more effective in addressing queries and engaging in dynamic conversations.

The best chatbot solution depends on several factors. Familiarize yourself with these considerations to understand what makes an AI chatbot right for your business:

• Align use cases: Ensure the chatbot’s abilities align with your needs to get the maximum benefits. For instance, if a business prioritizes CX, choosing a specialized chatbotrather than an AI chatbot for saleswould be ideal.
• Assess integration capabilities:If the AI chatbot integrates with your existing systems—messaging software, websites, CRM systems—you can seamlessly share information with it. Evaluate the availability of APIs and integration options that facilitate connections with third-party applications, enabling a cohesive workflow.
• Ensure it has a fast and easy setup:Pre-trained AI chatbots work right out of the box, but you’ll still need to determine if they require developer support, which may entail manual training and configuration. This will delay deployment and add to their total cost of ownership.
• Look for scalability and flexibility: Scalability allows the chatbot to handle increasing interactions without compromising performance, ensuring consistent and reliable service as the business expands. Flexibility is equally important, as it enables you to customize and update the chatbot to meet changing requirements, such as adjusting to shifts in business processes.
• Prioritize security:The AI chatbot should comply with customer data protection regulations and implement encryption protocols to secure user interactions. Verify the platform's privacy policies to ensure it handles user data responsibly and transparently. Look for options to customize data retention and privacy settings.
• Understand the AI model sophistication: Know the foundational data the AI bot is trained on, since this will influence its capabilities and effectiveness. High-quality AI chatbots often use NLP and ML algorithms to understand inputs and generate contextually relevant responses. Check for features like context retention, customer sentiment analysis, and generative AI.

It’s also important to consider factors like selecting a chatbot with quality support that is regularly updated to offer the best user experience.

1. ChatGPT

Best for general use

Model:GPT-4o mini, GPT-4o, GPT-4

When OpenAI released ChatGPT in late 2022, it became the fastest-growing consumer app ever. It arguably popularized AI, making generative and conversational AI tools accessible to everyone.

ChatGPT offers writing, summarization, coding, research, and parsing capabilities. ChatGPT can also integrate with add-ons and plugins to access accurate information or use third-party services. Some notable plugins include:

• OpenTable for restaurant reservations
• KAYAK for travel bookings
• Instacart for local grocery shopping
• Speak for learning other languages

Since its launch, ChatGPT has rolled out new iterations of the original intent model, such as GPT-4o, which natively supports voice-to-voice interactions. Free plan users have some access to GPT-4o, but once they meet the usage cap, it defaults to the more limited GPT-4o mini model. 

ChatGPT also offers DALL·E, an AI-powered image generator, in ChatGPT Plus and Enterprise. Users can enter a prompt or describe an image through voice chat. Based on the description, DALL·E will generate an output, such as a picture, logo, or comic strip.

The AI chatbot has a few noteworthy limitations, like it might lack real-world knowledge and struggle with understanding context, leading to occasional irrelevant responses. Additionally, it can be susceptible to generating biased or inaccurate responses when prompted to do so.

Pricing:Paid plans start at $20 per user/month for an individual account. A free plan is available.

Pros	Cons
Web browsing File uploads Image generation	Risks of inaccurate information The free plan has limited access to advanced AI models and features

The AI will also share these insights with agents to provide helpful context and suggestions for solving the issue.

AI can surface similar tickets, turn a few bullet points into a full reply, change the tone, and summarize conversations to boost agent productivity. The agent copilot can take the pressure off agents by proactively offering reply drafts or next steps during customer interactions.

Additionally, Zendesk AI agents automate up to 80 percent of support requests, leveraging company knowledge and fully customizable conversation flows to resolve even the most sophisticated use cases. With Zendesk, companies get the flexibility and control to deliver customer support their way—whether through fully autonomous AI agents, workflow automation, or human touch.

Chatbot users can also view AI-powered results using the Bing search engine or app, but have to download Microsoft Edge to get the full Copilot conversational experience. Copilot has a visual search and an enterprise-level chatbot that offers security features and citations for the answers it provides.

Microsoft Copilot has a free version, but there's a condition: Users must access the chatbot through Microsoft's Edge web browser. If the user has other browsers like Chrome, they will be restricted to five replies per conversation.

6. Claude

Best for creative writing

Model: Constitutional AI (CAI), Claude 3 and 3.5

Claude is a generative AI chatbot from Anthropic that uses Constitutional AI (CAI). The response bot software refers to itself as “self-contained,” meaning it responds to general queries without searching the internet. Claude uses the HHH system architecture, which stands for “helpful, honest, and harmless.”

Users can modify Claude’s behavior by prompting it with background knowledge to receive the desired responses. Along with the free plan, Claude has paid plans—Pro, Team, and Enterprise—that can help users with text analysis, summarization, and creative content generation.

While deploying Llama 3 is tailored for developers, users can experiment with it on the Llama2.ai website to understand its responses. The output is straightforward and less refined than other chatbots, providing a basic exploration platform with minimal customization controls.

The newest update, Llama 3.2, offers multiple model sizes: 1B, 3B, 11B, and 90B parameters. The larger model can understand more complex data and concepts but requires more computing power and can be more difficult to use.
