Best for

✓ Best for

Teams needing low-latency open-source model inference, fine-tuned model serving, or building compound AI applications

✓ Best for

Developers prototyping with open-source ML modelsFastest path from model selection to working API without any infrastructure
Applications with bursty, unpredictable ML inference needsScale-to-zero means you only pay when models are actually running
Teams without ML ops expertiseReplicate handles GPU provisioning, scaling, and model versioning

Not ideal for

✕ Not for

Teams that only need flagship proprietary models like GPT-4 or Claude

✕ Not for

High-volume production inference with predictable loadDedicated GPU instances on cloud providers are cheaper at scale
Latency-sensitive real-time applicationsCold start times of 5-30 seconds are unacceptable for interactive use cases
