As these developments unfold, data privacy remains a paramount concern, and measures have been taken to ensure that user information is protected and secure. Among the various ways to apply LLMs in business scenarios, there's a growing anticipation of using the Llama2 model as a stand-alone solution to establish a personalized AI engine.
If you’ve been waiting for an open alternative to closed-source chatbots, Llama 2-Chat is likely your best choice today!
In this tutorial, we will delve into how to create an efficient AI chatbot based on Llama2 using the Sendbird conversation platform.
LLM-based AI chatbots: Transitioning from a basic bot to a tailored AI assistant
AI chatbots, designed to offer comprehensive responses to user queries by learning from previous chat data, significantly improve user experiences. Such AI chatbots uplift applications or services by providing richer and more immersive user interactions.
With Sendbird, there's an opportunity to integrate a variety of LLM models, and now, there's a chance to directly utilize Llama2. By adopting Llama2, there's no longer a need to pass data to shared resources, ensuring data remains secure with Sendbird's high-level security measures. Furthermore, by leveraging Sendbird's technology, one can harness existing chat data for learning, paving the way for a more specialized chatbot experience.
The upcoming guide will illustrate how Sendbird's AI chatbot effectively harnesses the capabilities of Llama2.

- System prompt
`System prompt` is very good at telling Llama 2 who it should be or constraints for how it should respond.
ex) You are a customer service chatbot.
- Source
You can input data into the ChatBot's knowledge base. The ChatBot will generate appropriate answers based on the input data.
File
ex) Easy_recipes.pdf
URL
- Max tokens (1 ~ 2048)
Model generates text until the output length (excluding the input context length) reaches max_new_tokens. If specified, it must be a positive integer.
- Temperature (0.0 ~ 1.0)
Controls the randomness in the output. Higher temperature results in output sequence with low-probability words and lower temperature results in output sequence with high-probability words. If temperature -> 0, it results in greedy decoding. If specified, it must be a positive float.
- Top P (0.0 ~ 1.0)
In each step of text generation, sample from the smallest possible set of words with cumulative probability top_p. If specified, it must be a float between 0 and 1.
3. Click Create.
Step 3: Testing your AI chatbot
After select your AI chatbot is created, you can start a test conversation directly from the web interface.
Step 4: Fine-Tuning (Reach Out to the Sales Team)
The currently available Llama2 is based on the 7B model. By utilizing larger models and training with managed data, one can achieve a desired level of LLM ChatBot performance.
At Sendbird, we offer access to chat history and have the expertise to train and provide tailored models. One can conduct training by combining the fundamental training dataset with Sendbird's chat history.
