Migration TODO List

Completed Tasks

• Initial Go project setup
• Database schema & migrations (hardcoded in db.go)
• Configuration loader (Viper)
• Auth Middleware (scoped to /v1)
• Basic Provider implementations (OpenAI, Gemini, DeepSeek, Grok)
• Streaming Support (SSE & Gemini custom streaming)
• Archive Rust files to rust branch
• Clean root and set Go version as main
• Enhanced helpers.go for Multimodal & Tool Calling (OpenAI compatible)
• Enhanced server.go for robust request conversion
• Dashboard Management APIs (Clients, Tokens, Users, Providers)
• Dashboard Analytics & Usage Summary (Fixed SQL robustness)
• WebSocket for real-time dashboard updates (Hub with client counting)
• Asynchronous Request Logging to SQLite
• Update documentation (README, deployment, architecture)
• Cost Tracking accuracy (Registry integration with models.dev)
• Model Listing endpoint (/v1/models) with provider filtering
• System Metrics endpoint (/api/system/metrics using gopsutil)
• Fixed dashboard 404s and 500s

Feature Parity Checklist (High Priority)

OpenAI Provider

• Tool Calling
• Multimodal (Images) support
• Accurate usage parsing (cached & reasoning tokens)
• Reasoning Content (CoT) support for o1, o3 (need to ensure it's parsed in responses)
• Support for /v1/responses API (required for some gpt-5/o1 models)

Gemini Provider

• Tool Calling (mapping to Gemini format)
• Multimodal (Images) support
• Reasoning/Thought support
• Handle Tool Response role in unified format

DeepSeek Provider

• Reasoning Content (CoT) support
• Parameter sanitization for deepseek-reasoner
• Tool Calling support
• Accurate usage parsing (cache hits & reasoning)

Grok Provider

• Tool Calling support
• Multimodal support
• Accurate usage parsing (via OpenAI helper)

Infrastructure & Middleware

• Implement Rate Limiting (golang.org/x/time/rate)
• Implement Circuit Breaker (github.com/sony/gobreaker)

Verification

• Unit tests for feature-specific mapping (CoT, Tools, Images)
• Integration tests with live LLM APIs
