Retail Spotlight: Personalisation with Open-Source Models

September 18, 20261 min read

Personalisation is a natural fit for retail, but sending every customer interaction to an external service raises cost and data-protection questions. Self-hosted open-source models offer an alternative.

Why retailers are looking at open-source

  • Data control: customer behaviour data stays in your environment.
  • Predictable cost: a fixed infrastructure bill instead of per-call pricing at peak.
  • Customisation: models can be tuned on catalogue and brand language.

Typical use cases

  1. Product descriptions and category copy at scale
  2. Search query understanding and recommendations
  3. Conversational shopping assistants grounded in live inventory

Self-hosting shifts effort from vendor management to operations. Budget for both.

What to weigh

Open-source models require engineering capacity for hosting, monitoring and updates. For many retailers a hybrid approach works best: self-host for high-volume, sensitive workloads and use hosted APIs elsewhere.
