Description:
Revolut ditches Claude as it lays out a plan to use self-hosted models but infrastructure costs are still eye-watering.

90% in less than a year.

But the London-headquartered digital bank hasn't cut AI out altogether, instead it's replaced those costly workloads with self-hosted, open-weight models from China's Z.ai. By derestricting itself, the company now says its developers can use AI much more freely without worrying about token limits, which in turn has also improved productivity. Latest Videos From TechRadar Watch full video here: Revolut cuts Claude for self-hosted, open-weight Chinese models Revolut seems pretty au-fait with the world of AI, having previously experimented with Google 's Gemini before opting to use
Anthropic's Claude, but some heavy users were said to be spending thousands
of dollars per month on tokens without generating the equivalent ROI.

"We were highly skeptical about the cost of AI," Revolut Infrastructure Lead David Abitbol said in a conference last month (via The Register ). "When we launched it we launched it with strict budget limits." You may like Dont follow the herd on AI cost optimization control compute this way AIs

Speaking separately at GTC Berlin , Abitol also noted that Revolut's self-hosted option resulted in a 70% improvement in lead time productivity, and a 60% improvement in coding time productivity. He also praised Z.ai's GLM models for their data privacy and auditability. Are self-hosted models
cheaper to run? It seems that GLM-5.1 brought inference costs down to around $0.30 per million input/output tokens, or around one-tenth the cost of
similar commercial costs. Now, Revolut can operate its own inference infrastructure to manage its own capacity. Are you a pro? Subscribe to our newsletter Sign up to the TechRadar Pro newsletter to get all the top news, opinion, features and guidance your business needs to succeed! Contact me

However, with great flexibility comes great cost. While costs associated with direct model usage have been slashed, self-hosting requires significant
outlay in terms of hardware and infrastructure. GPUs, maintenance,
electricity and maintenance and some of the key areas that will likely have seen a major increase in expenditure.

The bank now reportedly has 56 Nvidia B200 GPUs, plus the model alone needs around 380GB of GPU memory and that excludes the estimated 6 to 26GB of
memory per user for context retention.

Ultimately, it's proof that artificial intelligence is a costly beast and deploying it aimlessly in a hope to save time is a poor strategy. But with more companies ditching commercial AI from the likes of Claude in favor of self-hosting, it begs the question whether using less advanced models for mundane work and even self-hosting over renting could improve the economics
in the years that come.

All of this, of course, against a backdrop of cost unpredictability , which seems to be hitting companies harder than high costs alone.

"Open source is now a priority at Revolut, and our economics are favorable," Abitol said. "The billing is flat, we don't have any bill shock at the end of the month, and the frontier is the exception." Follow TechRadar on Google
