Footprint
Minimum to load the published checkpoint with a small KV cache. Long contexts and high concurrency need more; quantizing a 16-bit checkpoint needs less. You don't pick hardware on sference: you choose a performance tier and we size and run the deployment.

FAQ
Can I run chandra-ocr-2 on a dedicated deployment in Europe?
Yes. sference deploys chandra-ocr-2 on GPU capacity reserved for you, behind a private endpoint, with every request processed on European GPUs and logged in your audit trail. Tell us your expected volume and latency targets with the form on this page and we come back with a sizing and a quote.
How many GPUs does chandra-ocr-2 need?
The published checkpoint is about 11 GB (BF16), so loading it takes at least 1 GPU with 80 GB of memory each, or 1 GPU with 141 GB each. Long contexts and high concurrency need more for the KV cache; quantization needs less. You don't pick hardware on sference: you choose a performance tier and we size the deployment.
Is chandra-ocr-2 licensed for commercial use?
chandra-ocr-2 is published under the Custom license license. Custom license from the model maker (openrail). Review the terms on the model page before production use.
How is a dedicated deployment priced?
Per GPU-hour on a monthly commitment, sized to your throughput and latency targets.
