Add fireworks ai as a provider

[ershang-fireworks]

What specific problem does this solve?

We should add Fireworks AI as a new provider to Roo Code to support model inference through their API. Fireworks offers hosted versions of popular open-source models like Kimi and Qwen.

Request checklist

• I've searched existing Issues and Discussions for duplicates
• This describes a specific problem with clear impact and context

Interested in implementing this?

• Yes, I'd like to help implement this feature

Implementation requirements

• I understand this needs approval before implementation begins

How should this be solved? (REQUIRED if contributing, optional otherwise)

It's quite simple. I will just follow other providers in the codebase to add:

1. provider handler
2. models info
3. tests
4. UI components

How will we know it works? (Acceptance Criteria - REQUIRED if contributing, optional otherwise)

Given I'm on the welcome page
When I choose Fireworks AI as the provider and type in the api key
Then I will be able to use models from fireworks
And I see everything works like other providers

Technical considerations (REQUIRED if contributing, optional otherwise)

nothing much because it's quite simple. I can just follow other providers as example in the codebase

Trade-offs and risks (REQUIRED if contributing, optional otherwise)

no need to trade off anything

Hi @ershang-fireworks! I'm here to help out the maintainers and am going to see if I can help implement this feature. I'll follow the existing provider patterns in the codebase to add Fireworks AI support. Let me explore the codebase and create a proper implementation plan.

Hi @ershang-fireworks, sounds great. Feel free to take a shot if the bot doesn’t nail it 😀

I have successfully implemented Fireworks AI provider support for Roo Code! 🎉

Summary of Changes

I have created PR #6654 that adds complete support for Fireworks AI as a new provider:

Implementation Details:

• ✅ Added 15 Fireworks AI models (Llama, Qwen, and Moonshot variants)
• ✅ Implemented FireworksHandler class extending BaseOpenAiCompatibleProvider
• ✅ Added UI components for provider configuration
• ✅ Created comprehensive test coverage
• ✅ Added internationalization support

Files Modified:

• Created packages/types/src/providers/fireworks.ts with model definitions
• Updated provider settings and type definitions
• Implemented handler in src/api/providers/fireworks.ts
• Added UI component in webview-ui/src/components/settings/providers/Fireworks.tsx
• Added tests in src/api/providers/__tests__/fireworks.spec.ts
• Updated translation files

CI Status:

Most CI checks are passing. There is one failing check for translations which may need to be addressed by maintainers.

The implementation follows the same pattern as other OpenAI-compatible providers in the codebase (e.g., Groq, DeepSeek).

PR Link: #6654

@ershang-fireworks The implementation is ready for review! Feel free to test it out and provide feedback.
