feat(dashboard): configure main + auxiliary models from Models page (#17802)
Dashboard Models page was analytics-only — no way to pick a model as main
for new sessions or override an auxiliary task slot without hand-editing
config.yaml or running a /model slash command inside a chat.
Changes:
- hermes_cli/web_server.py: three REST endpoints (GET /api/model/options,
GET /api/model/auxiliary, POST /api/model/set). Reuses
list_authenticated_providers() from model_switch.py so the REST path
surfaces the same curated model lists as the TUI-gateway model.options
JSON-RPC. POST /api/model/set writes model.provider + model.default for
scope=main, and auxiliary.<task>.{provider,model} for scope=auxiliary
(with task="" meaning 'all 8 slots' and task="__reset__" resetting them
to auto).
- web/src/components/ModelPickerDialog.tsx: accepts an optional loader +
onApply pair so it works without an open chat PTY. ChatSidebar's
gw-WebSocket path still works unchanged (back-compat).
- web/src/pages/ModelsPage.tsx: Model Settings panel at the top showing
main model + collapsible list of 8 auxiliary tasks with per-row Change
buttons and Reset all to auto. Every existing model card gets a
'Use as' dropdown for one-click assignment to main or any aux slot.
Cards badged 'main' or 'aux · <task>' when currently assigned.
- website/docs/user-guide/configuring-models.md: new docs page walking
through both UI paths, aux task override patterns, troubleshooting,
plus REST/CLI alternatives.
- Screenshots under website/static/img/docs/dashboard-models/.
Applies to new sessions only — running sessions keep their model (use
/model slash command to hot-swap a live session). No prompt-cache
invalidation on existing sessions.
