Everything your training pipeline needs
Petabyte-scale dataset storage
Store training corpora and raw crawl data with no practical size limits.
High-throughput reads
Sustained multi-Gbps reads so your GPU cluster never waits for the next batch.
Immutable object lock
Lock objects so your training data can't be altered or deleted, even with your keys.
No egress fees, ever
Move or replicate data across regions and providers with zero egress charges.
S3-compatible, drop-in
Works with PyTorch, HuggingFace, Ray Data, and any S3-compatible SDK.
Presigned URL sharing
Share checkpoints with time-limited presigned URLs, no credentials to hand out.
Four steps to zero egress bills
Create a bucket
Pick a region and create a bucket in seconds from the dashboard.
Swap your endpoint
Point your S3 endpoint at Fil One. No SDK changes needed.
Upload your data
Migrate data with rclone, the AWS CLI, or any S3 library.
Train with confidence
Your data stays intact, GPUs stay busy, and egress bill is zero.
Frequently asked questions
The S3-compatible API means anything built for AWS S3 works here too. Point your SDK or CLI at our endpoint and authenticate with your API keys.
Security comes first in the S3-compatible design: setup and migration stay simple, and buckets are private by default. Public access with full S3 parity is coming soon.
Read Fil One docs, access the app to get started with no code required, or talk to someone on our team to get started.
Encryption is industry-standard, with per-object data encryption keys that protect your data regardless of which provider it's stored with. SOC 2 Type II and ISO 27001 certifications are actively in progress. Reach out to security@fil.one if you'd like to be notified when those finalize, or have other questions about security.
After you create an account and provision your first bucket, migrating to Fil One is straightforward with our S3-compatible interface. Integrate directly into your codebase with any S3-compatible SDK, or migrate your data with a single AWS CLI command.
Enterprise teams who want more hands-on support can work directly with our team through every step of migration. Reach out at sales@fil.one to get started.
