Learn why Go was chosen over Rust and Python for building an LLM proxy, and the key engineering trade-offs that led to this decision

intermediate Published 3 Apr 2026
Action Steps
  1. Evaluate the performance requirements of your LLM proxy using Go, Rust, and Python
  2. Compare the memory safety features of Rust and Go for building a reliable LLM proxy
  3. Assess the development speed and ease of use of Python for building an LLM proxy
  4. Consider the concurrency features of Go for handling multiple requests to the LLM proxy
  5. Test the performance of your LLM proxy using different programming languages to determine the best choice
