feat(openrouter): Add OpenRouter Provider Support with Dynamic Model Loading

Overview

This PR adds OpenRouter as a model provider in Continue, with automatic model loading from OpenRouter JSON data and an enhanced model selection UI featuring fuzzy search.

Changes Made

1. OpenRouter Model Data Processing (`openRouterModel.ts`)

New file to convert OpenRouter JSON model data into Continue's ModelPackage format.
Implements automatic model discovery from openRouterModels.json.
Features:
- Converts OpenRouter model metadata to Continue's ModelPackage type.
- Extracts provider names, context lengths, and descriptions.
- Generates reference URLs to OpenRouter model pages.
- Error handling for malformed model entries.
- Exports both keyed object (openRouterModels) and array (openRouterModelsList) formats.

Files:

2. Provider Configuration (`providers.ts`)

Added OpenRouter provider configuration with setup instructions and metadata.
Integrated OpenRouter models into provider packages by importing openRouterModelsList.
Configured provider metadata:
- Title: OpenRouter
- Icon: openrouter.png
- API Key URL and documentation links
- Completion parameters input fields

File:

gui/src/pages/AddNewModel/configs/providers.ts

3. Enhanced Model Selection UI (`ModelSelectionListbox.tsx`)

Added fuzzy search to the model/provider selection dropdown.
Features:
- Sticky search box with magnifying glass icon.
- Fuzzy matching algorithm that matches characters in order and gives bonuses for consecutive matches.
- Real-time filtering and smart result sorting by match quality.
- Search persistence behavior: clears on provider change or dropdown close.
- Empty state message when no matches are found.
- New searchPlaceholder prop for context-specific labels.

File:

gui/src/components/modelSelection/ModelSelectionListbox.tsx

Other modified imports:

gui/src/pages/AddNewModel/configs/models.ts

Search Algorithm Details

Matches partial strings while preserving character order.
Rewards consecutive character matches with bonus points.
Normalized scoring for fair ranking across varying text lengths.
Supports both "Search models..." and "Search providers..." contexts.

UI Improvements

Search box is sticky at the top of dropdown.
Respects the existing theme (no custom colors).
Uses Heroicons: @heroicons/react/24/outline.
Smooth transitions and proper focus management.

Technical Details

New Dependencies

No new external dependencies added.
Uses React hooks: useState, useEffect, useMemo.
Uses existing Continue UI components.

File Structure (new / modified)

gui/src/pages/AddNewModel/configs/
├── openRouterModel.ts (NEW)
├── openRouterModels.json (NEW)
├── models.ts (modified imports)
├── providers.ts (added OpenRouter config)

gui/src/components/modelSelection/
├── ModelSelectionListbox.tsx (enhanced with search)

Usage Examples

For users:

Go to Add New Model settings.
Select "OpenRouter" from providers (or search).
Enter OpenRouter API key.
Browse available models and use fuzzy search:
- Search examples: gpt, claude, llama.

Files Added

gui/src/pages/AddNewModel/configs/openRouterModel.ts (new)
gui/src/pages/AddNewModel/configs/openRouterModels.json (new)
Icon: openrouter.png (ensure included in repo assets)

Tests / Verification

Manual:
- Open Add New Model UI and select OpenRouter.
- Confirm models load from openRouterModels.json.
- Verify fuzzy search returns expected results and empty state message is shown for no matches.
Edge cases:
- Malformed entries are skipped and logged.
- Short inputs and single-character searches return sensible results.

Notes for Reviewers

No runtime dependencies added.
Ensure openRouterModels.json and openrouter.png are included in packaged assets/build.
Users must provide an OpenRouter API key in settings (consider documenting in README or provider docs).

Breaking Changes

None. If any breaking API changes were introduced, the title should include a ! and a BREAKING CHANGE section.

Changelog (one-liner)

<violation number="1" location="gui/src/pages/AddNewModel/configs/openRouterModel.ts:60">
Because nearly every OpenRouter model populates `architecture.modality`, this condition marks all of them as not open source—including open-weight models—so they disappear from any open-source-only filters.

I have read the CLA Document and I hereby sign the CLA

@partha-sarathyy this is great!
The only change I'd request is could you write a super simple script or similar to eliminate all the unused parameters/extra data from the operouter models JSON to whittle it down to a more manageable size? I think it should be a few hundred lines tops. You might even just prompt Continue to rewrite it with the following changes:

Descriptions need to be shorter to fit in the UI. Once brief sentence max
All unused fields should be eliminated (most of them)

You could include brief instructions on where you got the JSON and the prompt you used to clean it up, in a comment

partha-sarathyy · 2025-11-19T05:56:37Z

@RomneyDa thanks for the review.
As per your suggestion i removed most of the unwanted properties. But just to be sure are these below properties enough or should i add any additional properties

Interface OpenRouterModel {
  id: string;
  name: string;
  description: string;
  context_length: number;
  hugging_face_id: string;
}
