Arch Gateway (now Plano) - Pros & Cons

Pros

  • ✓Moves routing, provider adapters, tracing, and guardrail hooks out of application code
  • ✓Apache-2.0 licensing supports inspection and self-hosting
  • ✓OpenAI-compatible APIs reduce integration changes
  • ✓Official repository includes a runnable two-agent travel example

Cons

  • ✗Arch Gateway has been renamed to Plano, making old product links stale
  • ✗Numeric production hosting and support prices are not public
  • ✗A gateway adds a critical network hop and operational dependency
  • ✗The staged MCP client-and-server claim is not substantiated by the current README

Replicate - Pros & Cons

Pros

  • ✓Largest catalog of community models — FLUX, Whisper, MusicGen, SVD all live here first
  • ✓Cog gives an honest portability story: same container runs locally, on Replicate, or on your own infra
  • ✓Per-output pricing for popular models hides GPU complexity for product teams
  • ✓Deployments let you trade cold-starts for predictable latency without leaving the platform

Cons

  • ✗Per-token text inference is usually cheaper on dedicated LLM providers like Together AI or Groq
  • ✗Cold-start latency on rare models can be 10–30s without a Deployment
  • ✗Quotas and per-account concurrency limits surprise teams that scale fast
  • ✗No built-in fine-tuning UI for most model families — you bring training to a Cog container
