Replicate is a cloud-based machine learning operations (MLOps) platform that enables developers to run, fine-tune, and deploy ML models through a simple API without managing infrastructure. Founded to democratize access to AI model deployment, Replicate was acquired by Cloudflare in early 2026 for approximately $350 million, integrating with Cloudflare's Workers AI ecosystem while continuing to operate independently.¹⁾

Replicate provides an API-first architecture that allows developers to run models with minimal code in Python, Node.js, or via HTTP requests. The platform hosts over 50,000 public models and approximately 100 curated production-ready models across categories including image generation, language modeling, audio processing, and video synthesis.²⁾

The platform uses Cog, an open-source tool for packaging ML models into standardized, reproducible Docker containers that serve as API endpoints. Cog handles dependency management, GPU configuration, and serving infrastructure automatically.

Running a model on Replicate requires only a few lines of code:

import replicate
output = replicate.run(
    "model_owner/model:version",
    input={"prompt": "example input"}
)

Models are versioned and automatically scaled based on demand, including scaling to zero when idle. Users can publish custom models via Cog containers, and the platform handles load balancing, versioning, and resource allocation. Cold boot times for fine-tuned models can be under one second.³⁾

Replicate supports fine-tuning of select models with custom datasets. Fine-tuned models are deployed on the same infrastructure as base models and benefit from optimized cold start times. The fine-tuning workflow integrates directly with the API, allowing programmatic training and deployment.

Replicate uses a per-second, pay-as-you-go billing model with no subscriptions or minimum commitments. Users pay only for active compute time.⁴⁾

For example, a 10-second inference on an A100 GPU costs approximately $0.014.

In November 2025, Cloudflare announced the acquisition of Replicate, completing the deal in early 2026. The acquisition integrates Replicate's model hosting capabilities with Cloudflare's global edge network, potentially reducing inference latency through distributed serving infrastructure.⁵⁾
