# NousResearch/hermes-agent · Parallelize endpoint probing on model refresh

## Open now

- 1 issue, 2 PRs open on GitHub.
- #123793: \[Bug\]: model.options refresh=true serially probes all user-provider endpoints (125s+ with many providers)
- PR #123831: perf(model-switch): parallel-prefetch user-provider endpoints on refresh
- PR #124036: fix(picker): probe custom endpoints in a bounded parallel wave on refresh

A bug was identified where refreshing model options serially probes all user-provider endpoints, causing very long waits (125s+). Related changes address this by switching to bounded parallel probing for both model switching and the picker.

## TL;DR

- 3 member(s): 1 open issue(s), 0 closed issue(s), 2 open PR(s), 0 merged PR(s), 0 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: 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.
