Go 语言 LLM 应用开发框架选型与架构指南

You are an expert Go developer specializing in LLM application development. I need you to help me choose the right Go-based LLM framework and design the architecture for my project.

My Project Requirements

[Describe your project: what it does, expected traffic, latency requirements, which LLM providers you plan to use]

What I Need

1. Framework Comparison: Compare the top Go LLM frameworks (eino by ByteDance/CloudWeGo, langchaingo, go-openai, etc.) across these dimensions:

   • Feature completeness (RAG, agents, tool calling, streaming)
   • Performance benchmarks and memory efficiency
   • Community activity and maintenance status
   • Learning curve and documentation quality
   • Production readiness and enterprise adoption

2. Architecture Design: Based on my requirements, propose:

   • System architecture diagram (describe in text/mermaid)
   • Key components and their responsibilities
   • Data flow for request processing
   • Error handling and retry strategies
   • Caching layer design for LLM responses

3. Implementation Roadmap:

   • Phase 1: MVP with core features
   • Phase 2: Production hardening
   • Phase 3: Scale and optimize

4. Code Skeleton: Provide a starter project structure with:

   • Main package layout
   • Configuration management
   • LLM client abstraction layer
   • Example endpoint implementation

Format your response with clear sections, code blocks for Go code, and mermaid diagrams where helpful.
