# Revolut says self-hosted GLM models cut its AI coding inference costs about 90%, replacing Claude Code and Codex as default

The Register reported on Nov 3, 2026 that Revolut made self-hosted Zhipu GLM models (GLM-5.1, then GLM-5.3 on 56 Nvidia B200s) the default coding assistant for ~2,000 engineers, cutting inference costs about 90% versus Claude Code and Codex.

## Key facts
- GLM-5.1 then GLM-5.3, on 56 Nvidia B200 GPUs
- ~2,000 engineers
- Self-hosting cost about a tenth of Codex or Claude Code
- HN: 190 points

## What happened

Revolut's engineering lead said: "We were highly skeptical about the cost of AI." A large Western bank-like firm standardising on a Chinese
open-weight model is a notable adoption signal.
