Follow the journey of a single message through our AI chat system in just 4 simple steps
User types a message in the chat interface. The message is captured by the JavaScript event listener.
messageInput.addEventListener('keydown')
Your message is formatted into a JSON payload and sent to the LLM API endpoint using the Fetch API.
fetch(endpoint, { method: 'POST', ... })
The AI model (like Llama 3.1 or Mixtral) processes your message and generates an intelligent response.
