# NousResearch/hermes-agent · MiniMax model config and pricing corrections

## Open now

- Nothing open on GitHub.

These issues and fixes address incorrect MiniMax model catalog entries, context lengths, auxiliary model selection, and a cost concern with the default highspeed auxiliary model being priced higher than expected. Changes update configuration details including base_url and thinking guard settings.

## TL;DR

- 4 member(s): 0 open issue(s), 1 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 #6082. Verify it addresses your case.
- **Recommended:** read PR #6082 (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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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

- #4082: \[Bug\]: Minimax Default Auxiallry Model MiniMax-M2.7-highspeed is twice the price at API rates

## Fix status

- Merged to main in PR #6082 (cited above). No release data is tracked. Verify downstream.
- Fix last verified (merged) `2026-04-08`. This confirmation is old and may be out of date (a revert/reopen would not have invalidated it here); re-verify.
