plenum /ˈpliːnəm/ — a space completely full. There is always room for you in the pool. That's the promise, and the name.
Cross-region H100 / B200 capacity, aggregated on demand. Requests route to the nearest, least-loaded cluster. No queueing at peak, no paying for idle.
Elastic pool · Auto routingFully compatible with the OpenAI SDK and protocol: change one base_url and you are migrated. Streaming, function calling, structured JSON and batch all line up.
OpenAI-compatible · Zero rewriteSOC 2 Type II, zero-retention inference, region pinning that keeps data in-country. Enterprises can opt for dedicated VPC clusters or fully private deployment.
SOC 2 · Zero retention · VPCGPU clouds, AI compute centers and enterprises with idle clusters can list capacity for rent. Traffic is allocated by measured performance — run reliably, earn more. Every call is metered per token, auditable line by line, settled monthly.
