Streaming enables word-by-word responses that feel natural in live chat. Combined with low latency, customers get instant help without waiting for full response generation.
Function calling lets AI access customer records, create tickets, update orders, and trigger workflows in your CRM - turning a chatbot into a capable support agent.
JSON mode enables structured classification of incoming requests - categorizing issues, extracting priority levels, and routing to the right team automatically.
A support bot handling thousands of conversations daily generates massive token volumes. Budget models under $1/1M tokens can reduce costs by 90% versus premium models while maintaining quality.
