# NousResearch/hermes-agent · ZAI/GLM model name and auxiliary provider corrections

## Open now

- Nothing open on GitHub.

Several issues with GLM model names having dots stripped (causing 'model not found' errors) on ZAI and OpenCode Zen providers were addressed, along with corrections to how auxiliary vision models and provider overrides are handled.

## TL;DR

- 5 member(s): 0 open issue(s), 2 closed issue(s), 0 open PR(s), 1 merged PR(s), 2 PR(s) closed without merging.
- A fix was merged to main in PR #8794. Verify it addresses your case.
- **Recommended:** read PR #8794 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## 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evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.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 `0.34`: 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

- #7475: \[Bug\]: Select Model GLM-4.7 get "提示模型不存在，请检查模型代码"
- #60381: bug: zai provider vision — glm-4v-flash returns 1211 '模型不存在' despite model working via direct API

## Fix status

- Merged to main in PR #8794 (cited above). No release data is tracked. Verify downstream.
- Fix last verified (merged) `2026-04-13`. This confirmation is old and may be out of date (a revert/reopen would not have invalidated it here); re-verify.
