## Key points

- Revolut says self-hosted AI cut coding inference costs by about 90 per cent.
- Around 2,000 engineers use the tools, with coding time down 60 per cent.
- Cheap tokens let AI handle debugging and project tickets more freely.

## Summary

Revolut says it cut the cost of AI coding by about 90 per cent in under a year by making self-hosted models its default, rather than relying mainly on commercial tools such as Claude. The British fintech also reported faster coding and shorter delivery times across roughly 2,000 engineers, with cheaper access allowing AI to take on routine work beyond writing code.

The company moved from Gemini and Claude Code to GLM models developed by China’s Z.ai, and now serves GLM-5.3 on 56 Nvidia B200 GPUs. Revolut says GLM-5.1 tokens cost about $0.30 per million, around a tenth of the price of OpenAI’s Codex or Anthropic’s Claude Code. It tuned the system to deliver responses in under three seconds and around 200 tokens a second; other models remain in use for tasks such as working with images.
