Unlimited Open Source Models
Get PlanLast updated · By ModelsLab Engineering
Replicate bills two ways: per output for popular public models (FLUX.1 [dev] $0.025 per image) and per second of GPU time for everything else (H100 $5.49/hr, L40S $3.51/hr), checked September 23, 2026. A private deployment kept online on one L40S costs about $2,527 a month before it makes a single image.

ModelsLab plan prices from the live plans table, 2026-09-23. FLUX.1 dev (model_id flux) is self-hosted and included in Open Source Unlimited, which runs up to 15 generations in parallel.
Popular official models such as the FLUX family carry a per-output price, shown on the model page. Most community models instead bill the seconds of hardware time each prediction uses, so the cost of one image depends on the GPU and on how long the model takes.
For private models and deployments, Replicate's pricing page says you pay for all the time instances are online: the time they spend setting up, the time they spend idle waiting for requests, and the time they spend active. Keeping one L40S warm around the clock is $2,527.20 for 30 days at $3.51 per hour. Scaling to zero avoids idle cost but brings back cold starts.
Replicate's billing documentation says purchased credit is valid for one year from the purchase date and is not refundable.
Cloudflare announced on November 17, 2025 that it had agreed to acquire Replicate. Replicate now operates as part of Cloudflare, and replicate.com still publishes its own per-second and per-output prices, which are the figures on this page. Check the pricing page again before you budget, because the parent company now sets the roadmap.

“Sudden 3x price hike with terrible output quality...the generation cost recently jumped from $0.16 to $0.50.”
“First they require you to add money to your account for future credits, but after a year they remove the money from your account.”
