Developer proposes 4-state model for LLM call outcomes

A developer has proposed a new model for handling Large Language Model (LLM) calls within complex workflows, moving beyond simple try/catch error handling. This model introduces four distinct outcomes: OK (successful result), DEGRADED (usable fallback output), ABSTAINED (no action needed, pre-determined), and FAILED (unrecoverable error). This approach aims to provide clearer distinctions for workflow steps, preventing the need for complex reverse-engineering of errors. The design emphasizes type safety, ensuring that only successful or degraded results carry usable values, while also separating operational metrics from sensitive LLM output for safer logging. AI

IMPACT This proposed model could lead to more robust and manageable LLM integrations in complex software systems.

    OK, DEGRADED, ABSTAINED, FAILED: Designing a Typed Outcome Model for LLM Calls

    <p>Most LLM-calling code I've seen treats an LLM step like an HTTP request: try/catch, retry a couple times on failure, throw if it still doesn't work. That model breaks down fast once an LLM call is one step inside a larger workflow, because "it didn't work" isn't actually one o…
