Deployment profile

Architecture: GptOssForCausalLM
Licence: Apache-2.0
Minimum VRAM: ~44GB
Context: 128K tokens

Recommended: L40S 48GB. VRAM is an estimate and increases with context, cache, concurrency, and runtime overhead.

GPU deployment scenarios

Estimated from parameter count and quantisation. Will switch to “Verified by Badgr” once a real run backs a tier.

Testing

L40S 48GB

Short context, low concurrency

Small production

A100 80GB

8K context, 1-4 concurrent requests

Higher throughput

H100 80GB

32K context, continuous batching

Large production

L40S 48GB

Higher concurrency

Estimated — multimodal inputs, long context, and concurrency all increase real VRAM use beyond this estimate.

Also runs well on A100 80GB, H100 80GB. Available in United States, Europe, Asia Pacific.
