+# Task ID: 35
+# Title: Integrate Grok3 API for Research Capabilities
+# Status: cancelled
+# Dependencies: None
+# Priority: medium
+# Description: Replace the current Perplexity API integration with Grok3 API for all research-related functionalities while maintaining existing feature parity.
+# Details:
+This task involves migrating from Perplexity to Grok3 API for research capabilities throughout the application. Implementation steps include:
+
+1. Create a new API client module for Grok3 in `src/api/grok3.ts` that handles authentication, request formatting, and response parsing
+2. Update the research service layer to use the new Grok3 client instead of Perplexity
+3. Modify the request payload structure to match Grok3's expected format (parameters like temperature, max_tokens, etc.)
+4. Update response handling to properly parse and extract Grok3's response format
+5. Implement proper error handling for Grok3-specific error codes and messages
+6. Update environment variables and configuration files to include Grok3 API keys and endpoints
+7. Ensure rate limiting and quota management are properly implemented according to Grok3's specifications
+8. Update any UI components that display research provider information to show Grok3 instead of Perplexity
+9. Maintain backward compatibility for any stored research results from Perplexity
+10. Document the new API integration in the developer documentation
+
+Grok3 API has different parameter requirements and response formats compared to Perplexity, so careful attention must be paid to these differences during implementation.
+
+# Test Strategy:
+Testing should verify that the Grok3 API integration works correctly and maintains feature parity with the previous Perplexity implementation:
+
+1. Unit tests:
+   - Test the Grok3 API client with mocked responses
+   - Verify proper error handling for various error scenarios (rate limits, authentication failures, etc.)
+   - Test the transformation of application requests to Grok3-compatible format
+
+2. Integration tests:
+   - Perform actual API calls to Grok3 with test credentials
+   - Verify that research results are correctly parsed and returned
+   - Test with various types of research queries to ensure broad compatibility
+
+3. End-to-end tests:
+   - Test the complete research flow from UI input to displayed results
+   - Verify that all existing research features work with the new API
+
+4. Performance tests:
+   - Compare response times between Perplexity and Grok3
+   - Ensure the application handles any differences in response time appropriately
+
+5. Regression tests:
+   - Verify that existing features dependent on research capabilities continue to work
+   - Test that stored research results from Perplexity are still accessible and displayed correctly
+
+Create a test environment with both APIs available to compare results and ensure quality before fully replacing Perplexity with Grok3.
