Own your data and win the long game with Cloudflare R2
The preferred storage option that doesn’t lock you in: zero egress fees.
Feed your AI training models from Cloudflare R2
Keep your future options open
In a rapidly-evolving AI landscape where new tools are offered, you cannot afford to be locked into platforms. Store data in R2 to reduce dependency on any specific GPU vendor now, and future-proof your data strategy.
Scale to petabytes and beyond
Unlocking value from your data with AI means your storage needs will continue to grow. Choose a trusted solution that scales with you. Store petabytes of high-value, frequently accessed datasets and checkpoints in R2, and focus on gaining deeper insights.
Deliver superior customer experience
Latency and speed are critical for AI workloads. Cloudflare’s global network delivers datasets from R2 with fast downloads and low-latency access. Use built-in security and orchestration tools to serve models, run inference, and deliver great experiences.
Why companies like Character AI trust R2 for multi-cloud training data
AI & ML teams rely on a multi-cloud architecture for training and processing requests, due to the price and availability of GPUs in the cloud. These distributed architectures require moving data between clouds, which lead to high bills in egress fees. As companies’ data grows, storage and egress get even more expensive.
The teams at Character AI migrated to R2 to store training and production data, and make it accessible to any cloud without incurring egress fees.
Now that R2 is the glue between their clouds, their teams are able to move their data freely and preserve their technical optionality. When cloud and compute needs change in the future, their data and workloads remain flexible.
MIGRATING YOUR DATA
Make a High-ROI move: migrate to R2
Migrate to R2 as a strategy to keep your data workloads flexible and compute agnostic
Enjoy the benefits of preserving your technical optionality with immediate ROI on every request served from R2 post-migration. You can quickly offset any migration expenses with savings from egress and storage costs.
Cloudflare’s data migration UI and API services help you quickly and easily copy objects into R2 from any S3-compatible object storage provider including MinIO, Wasabi, Backblaze B2, and DigitalOcean Spaces.
