SK Telecom enhances customer support for millions of Koreans with Claude in Amazon Bedrock
SK Telecom, Korea's #1 customer service provider for 27 consecutive years (NCSI), deployed Claude in Amazon Bedrock to power customer support for millions of Koreans. The deployment lifted in-call LLM response quality ratings by 34%, cut low-quality responses in SKT's Telco fine-tuned model by 68% versus the base, and reached ~89% of human agent quality in post-call processing — combining SKT's in-house RAG with Claude for end-to-end retrieval-augmented generation.
