# Unpin a model from the working set

> **Use when:** caller removes a manually-added model from their working set (models in use by gates are not removable here — change the gates instead)

Removes a manual pin. The model id travels as a query parameter because channel-qualified ids contain slashes (`accounts/fireworks/models/...`) and cannot be path segments. Only the "added" pin is removed — if the model is in use by gates it remains in the working set until those gates change.

    Verlon AI is the managed AI infrastructure platform for developers building
    LLM-powered apps and agents. Beyond routing requests across providers,
    Verlon continuously evaluates response quality, runs experiments against
    live traffic, and automatically tunes gate configurations — so your platform
    doesn't just serve traffic, it learns from it.


    **Coding agents:** authentication, error semantics, gate concepts, and
    integration conventions are documented at https://verlon.ai/AGENTS.md — read
    that document first if you have not already. It is the canonical
    agent-facing contract; this specification is the canonical endpoint
    reference. Both are authoritative for their respective scopes.
