# NousResearch/hermes-agent · models.dev catalog caching and network resilience

## Open now

- Nothing open on GitHub.

These items address blocking behavior and stale-cache handling when models.dev is unreachable, introducing ETag-based conditional requests, a no-network hot-path, and preferring stale cache over unsuccessful refreshes.

## TL;DR

- 4 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 2 merged PR(s), 1 PR(s) closed without merging.
- A fix was merged to main in PR #85555. Verify it addresses your case.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-85555`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.50`: 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.

## Closed / duplicate issues

- #35838: \[Bug\]: \`agent.models_dev.get_provider_info()\` blocks when \`models.dev\` is unreachable and local cache is stale
