Stitch Fix uses OpenAI's GPT-4 to summarize the accumulated notes and feedback that long-standing clients have shared with stylists over many orders, producing concise recaps that help stylists quickly understand a client's preferences before selecting items for a Fix. This is an internal tool that outputs to stylists, not directly to clients.
Details
Long-standing clients may have left dozens or even hundreds of notes and feedback entries over many orders. Stitch Fix confirmed in its June 2023 newsroom post that GPT-4 distills this freeform text at scale into concise client preference summaries. The summaries are provided to stylists as a tool to help them more accurately select items for each client's Fix. This practice was described as exploratory/being implemented as of June 2023.
