Improves the model dropdown:

  • Sorts the list alphabetically by developer and family
  • Adds options for FP8 and NVFP4 models and removes them from the main list to reduce its size
  • Allows for searching for models that are in the list by name.

Partially Resolves: #59 . Missing additions that would show the model's number of parameters and type (vision, text, etc) which will require modifications to AIC or integration with HuggingFace. See issue comments for discussion

Related: #69

Summary by CodeRabbit

  • New Features
    • Added a searchable model selector with grouped suggestions and custom model entry.
    • Added keyboard navigation, clearing, outside-click dismissal, and accessibility support.
    • Added filtering for tested models and optional FP8/NVFP4 variants.
    • Added match highlighting, helper text, testing-request links, and Hugging Face token-status messaging.
    • Updated performance, cache, and advanced estimation tools to use the new model selector.

📝 Walkthrough

Walkthrough

The change adds a shared grouped and searchable ComboBox for catalog and custom model selection. Three estimate views now pass catalog-derived items, supported models, and Hugging Face token status to the component.

Changes

Model selection

Layer / File(s) Summary
ComboBox contract and state
components/ModelComboBox/ModelComboBox.tsx
Adds grouped filtering, custom values, keyboard and mouse selection, tested-model filtering, selection restoration, and FP8/NVFP4 variant handling.
ComboBox rendering and support
components/ModelComboBox/ModelComboBox.tsx, components/ModelComboBox/ModelComboBox.module.css
Adds accessible option rendering, highlighted matches, custom entries, empty states, quantization controls, helper content, and component styling.
Estimate view integration
app/kv-cache/KvCacheCalc.tsx, app/performance/PerformanceEstimate.tsx, app/recommend/AdvancedEstimate.tsx
Replaces ModelInput with ComboBox and passes grouped catalog items, custom model support, supported models, and Hugging Face token data.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 66557

When the Tested only filter is enabled, selecting a different model may be replaced by the previously selected model, leaving the dropdown in an unexpected state. The change is otherwise mergeable with explicit owner follow-up on preserving deliberate user selections.

Pass the tested-model list to supportedModels.

ComboBox labels this filter Tested only, but each view passes aicModels, which is the complete catalog used to build the options. The filter therefore does not restrict normal catalog models.

Restore the switch focus indicator.

This rule removes the PatternFly switch focus outline and shadow. Keyboard users then have no visible focus indicator. Keep the PatternFly focus style, or add an equivalent visible indicator.

Keep a model selected while the filter is enabled.

If a user enables Tested only, selects another model, and then disables the switch, onChange(prevModel.current) restores the older model. This discards the user’s latest selection. Restore the prior model only when this switch automatically replaced an unsupported model.

Use PatternFly controls for the model selector.

ComboBox uses native input, button, and listbox elements with bespoke CSS across all three call sites. Replace them with PatternFly components or an approved PatternFly composition that preserves typeahead, grouping, and custom values.

Namespace option IDs for each ComboBox instance.

aria-activedescendant uses opt-<index>. Every opened ComboBox creates the same option IDs. Assistive technology can then resolve the active option to a different control. Prefix the IDs with id, or use React.useId().
