How are AI chatbots trained?
Most AI chatbots are built on large language models that were pre-trained on huge amounts of text and then tuned with human feedback to follow instructions. Businesses rarely retrain the model; they adapt it with instructions, connect it to company knowledge through retrieval, add example conversations, and improve it by reviewing transcripts and fixing gaps.
Layers of “training”
Why retrieval beats retraining for support
Company facts change often. Retrieval lets the bot use current information without retraining, and makes it possible to cite sources.
