Cloudflare Workers AI - Pros & Cons
Pros
- ✓Among the cheapest paths to production Llama inference at $0.011 per 1K Neurons with 10K free per day
- ✓Co-locates with Workers, Pages, and Vectorize for single-digit-millisecond RAG round trips on the edge
- ✓OpenAI-compatible endpoints mean existing OpenAI SDK code drops in with one URL change
Cons
- ✗Catalog is open-source-only — no GPT-5 or Claude (use AI Gateway or OpenRouter for those)
- ✗Throughput trails Groq on tokens-per-second for the largest Llama models
- ✗Vision and image generation model coverage is narrower than Replicate
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
