⚠️ Cons

OpenRouter

  • × Model routing obfuscates original provider for debugging
  • × China access requires proxy, unstable
  • × Aggregated API latency 15-30% higher than direct
  • × Non-deterministic provider selection
  • × Advanced features (fallback/routing) require paid plan

OpenAI

  • × Higher API costs (o1 series $15-60/M)
  • × China requires proxy for access
  • × Frequent output model updates, occasional API compatibility issues
  • × High token consumption, especially o1 series
  • × No special discounts beyond batch credits
