Founder of Replicate here. Also YC founder (W20). :)
It's also worth noting that we bill by the second for how long your prediction is running, and we don't bill for any idle time, so in practice Replicate works out cheaper for many workloads. We can give discounts if you're putting through a decent amount of traffic. We should be able to match Runpod's pricing.
