# NousResearch/hermes-agent · Plugin hook proposals for per-turn model routing

## Open now

- Nothing open on GitHub.

These items propose adding a plugin hook or callback that can override the model or provider selected for each individual LLM turn, with varying names and designs across the proposals. They share a common theme of enabling dynamic, per-turn routing decisions from plugin code, but differ in scope and API specifics.

## TL;DR

- 4 member(s): 0 open issue(s), 3 closed issue(s), 0 open PR(s), 0 merged PR(s), 1 PR(s) closed without merging.
- No fix has been merged to main; one or more PRs were attempted (see below).
- **Recommended:** review the prior/competing PR(s) below. A fix was attempted but not merged; your case may extend or revive that work.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.29`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
