Replicate
Replicate runs open-source and proprietary AI models through a cloud API, and lets developers fine-tune models or deploy their own without managing GPUs.
About this tool
Replicate lets developers run AI models with a few lines of code, without learning machine learning operations or managing GPUs. Its catalogue includes thousands of community-contributed open-source models as well as proprietary models for image generation, video, audio and language, each with a page showing inputs, examples and estimated costs.
Beyond running existing models, you can fine-tune a model on your own data or package and deploy a custom model, then call it through the same API. Pricing is usage-based: most models are billed by the seconds of hardware they use, while some are billed per input and output. Guides cover integrations such as serverless web apps and edge functions.
What you can do
Large model catalogue
Run community open-source models and hosted proprietary models for images, video, audio and text through one API.
Fine-tuning
Bring your own training data to create a fine-tuned version of a model, for example to capture a style or subject.
Custom deployments
Package and deploy your own models on Replicate’s infrastructure and scale them without running servers.
Usage-based billing
Pay per second of hardware or per input and output depending on the model, with estimates shown on model pages.
Who is it for?
- A developer adds image generation to a web app with a single API call.
- A design studio fine-tunes an image model on its own illustrations.
- A startup deploys a custom model without hiring infrastructure engineers.
Before you choose
Per-second billing depends on model speed and hardware, so test typical requests to estimate your monthly bill.
Community models differ in licence and quality; confirm usage rights before relying on one commercially.
Frequently asked questions
How does Replicate charge?
Most models are charged per second of compute on the chosen hardware, while a few are priced by input and output; you pay only for usage.
Can I train models on Replicate?
Yes, you can fine-tune supported models with your own training data and then run the resulting model via the API.
Do I need machine learning expertise?
No. Replicate is designed so developers can run models through a cloud API without managing infrastructure.
