Revolut moved about 2,000 engineers onto self-hosted GLM for coding, achieving 1/10th the cost and 70% faster lead time. They run 56 Nvidia B200 GPUs and pay a blended 30 cents per million tokens, roughly a tenth of Anthropic pricing.

Key points

  • Engineers: ~2,000 engineers on self-hosted GLM, 1/10th cost, 70% faster lead time.

  • Infrastructure: 56 Nvidia B200 GPUs, blended 30 cents per million tokens, about a tenth of Anthropic spend.

vLLM platform layers added: tenant keys, routing, GPU scheduling

vLLM in a pod is described as only the engine, and a platform must add tenant keys and budgets, inference-aware routing, and GPU scheduling. The article outlines where each responsibility belongs in a Kubernetes LLM inference platform. It also notes that GPU utilization alone was insufficient for autoscaling, using queue depth instead.

Key points

  • Tenant edge (LiteLLM) handles virtual keys, per-key budgets, model allowlists, rate limits, and spend records.

  • Inference-aware router (Gateway API Inference Extension) selects the replica with the healthiest queue and cache state.
