Description

Fastweb + Vodafone, an Italian telecom provider, uses Gemini to generate documentation directly from code for under-documented legacy services. The output is stored in Spanner as vector embeddings to form a searchable knowledge base, and a Gemini-powered chat interface lets developers ask natural-language questions about code. The source describes this as part of rebuilding its Customer 360 platform on Spanner and BigQuery and gives no quantified result for the Gemini workflow.
