Add Oracle Cloud Infrastructure (OCI) Generative AI Integration

[ahmedkall]

Description
LlamaIndex Python currently supports integration with Oracle Cloud Infrastructure (OCI) Generative AI service, allowing users to leverage both chat and embedding models. It would be valuable to have similar support in the TypeScript/JavaScript version of LlamaIndex.

Current Status

• Python version has full OCI Generative AI integration
• TypeScript/JavaScript version currently lacks this integration

Requested Features

1. Integration with OCI Generative AI service
2. Support for:
   • Access to pretrained models
   • Chat model integration
   • Embedding model integration
   • Custom model hosting capabilities

Benefits

• Consistency between Python and TS/JS implementations
• Enables TypeScript/JavaScript developers to utilize OCI's AI services
• Provides cloud-based model alternatives for TS/JS projects

Technical Considerations

• Will need to implement OCI authentication flow
• Consider creating modular integration similar to other LlamaIndex cloud provider implementations
• Should follow existing patterns for model integration in LlamaIndex.TS

Related Documentation

• Python version documentation available for reference
• OCI Generative AI service documentation can guide implementation

Would you be interested in this feature? Any thoughts on implementation priorities or specific aspects that should be considered?
