Revolut Talk: ~2,000 Engineers Default to Self-Hosted GLM-5.3 on ~56 B200s; Coding AI Bill ~1/10 of Claude/OpenAI
At AI Engineer NYC on 2026-10-13, Revolut AI ops lead David Abitbol said ~2,000 engineers now default to self-hosted GLM-5.3 on ~56 NVIDIA B200 GPUs at a blended ~$0.30 per million tokens—about one-tenth prior Anthropic/OpenAI invoices. Speaker charts claim ~60% better coding time and ~70% lead time. Claude Code/Codex remain hard-case exceptions; vision is routed elsewhere.

- Scale: ~2,000 engineers default to self-hosted GLM-5.3 on ~56 NVIDIA B200 GPUs; speaker blended cost ~$0.30 per million tokens
- Cost: invoice about one-tenth prior Anthropic/OpenAI spend; ~60% coding-time and ~70% lead-time improvements claimed (not isolated from other changes)
- Routing: GLM for text/code; vision to Gemini/GPT-class models; Claude Code/Codex kept for hard exceptions
- Ops: same GPU count tuned TTFT ~14.3s→1.7s and +76% RPS; sandbox approvals + telemetry stressed for bank compliance
