Jördening presents MVC approach and discriminator models for reliable LLM selection systems
↗
Jendrik Jördening shared engineering strategies for integrating LLMs into production selection systems, advocating an MVC pattern to separate concerns and discriminator models to validate outputs.
LLMs in production selection systems conflate model, view, and controller, making it difficult to convert text outputs to database IDs and integrate with existing infrastructure. Jördening's approach of restricting schemas, separating semantic extraction from deterministic code, and validating with discriminator models offers a concrete architecture for teams facing non-determinism and observability challenges.

LLMs collapse model, view, and controller into a single conversation history, creating integration problems when outputs must map to database integer IDs.
Context window limitations prevent feeding thousands of options to the LLM, requiring schema restriction and separation of semantic extraction from deterministic selection logic.
Discriminator models validate LLM choices, providing a check against non-determinism, prompt injection, and random outputs before they reach production systems.
