Foundational

🗂️ Scheduling & Orchestration

Node Lifecycle: Drain, Upgrade and ReturnFleet maintenance moves nodes through drain, repair and validation before returning them to service. Deadlines and concurrency limits keep that work within the available capacity.

📐 AI Systems Design🔒 Premium

Multi-Tenant Fine-Tuning ServiceA fine-tuning service turns a tenant’s dataset into an evaluated model or adapter. Its pipeline must protect data while scheduling training and serving the result efficiently.

Foundational

🖧 Hardware & Cluster Build-Out

Colocation, Power Contracts and Site SelectionA suitable site must deliver the required rack power, cooling and service capacity. Contract terms and facility lead times shape both cost and deployment dates.

🚀 Inference & Serving🔒 Premium

Reasoning Budgets and Answer LatencyReasoning tokens consume generation time and retained state before an answer becomes usable. Separate the first generated token from the first answer token, reserve output capacity, and evaluate reasoning limits against task success.
