Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
Lightning-fast object storage built for AI
Optimized throughput keeps GPUs and TPUs fed during training and inference so compute is not wasted on I/O bottlenecks.
Binary-level deduplication detects duplicate byte strings and versions, lowering the total cost of ownership for large datasets.
Drop into existing pipelines without changing your stack, working with Parquet, Iceberg and standard S3 tools.
Choose a managed serverless service hosted in EU Tier 1 datacenters, or deploy the Kubernetes-native Self-Hosted edition anywhere.
