Revolut moves about 2,000 engineers to an in-house open-weight AI model
The fintech reportedly made the self-hosted GLM model the default for coding work, with Claude Code and Codex kept as exceptions.
Key takeaways
- Revolut reassigned roughly 2,000 engineers to an open-weight AI model hosted internally, according to a post shared on X.
- The model, referred to as GLM, is now the default for coding tasks, with Claude Code and Codex listed as exceptions.
- The report frames the move around cost, efficiency and control over corporate AI tools.
- The account comes from a social media post, and Revolut has not been cited confirming the details.
What the report says
Revolut has moved about 2,000 engineers onto an open-weight AI model hosted inside the company for coding work, according to an analysis shared by Guillermo Flor on X and reported by Bitcoin Block. The model is referred to as GLM. Tools such as Claude Code and Codex are kept on an exceptions list rather than used by default.
Open-weight models are systems whose trained parameters are published, so a company can run them on its own infrastructure instead of sending work to a vendor's servers. The report presents the switch as a question of cost, efficiency and control over the tools a large company depends on.
Who is behind it
The report names David Abitbol, described as Revolut's head of operations, in connection with the change. It does not quote him directly or give a date for the switch.
Bitcoin Block frames the Revolut case as an example of a larger company choosing self-hosted, open models over proprietary ones. That framing is the outlet's own reading; the underlying claim traces back to a single post on X.
What is not confirmed
The account rests on a social media post, and the report does not say whether Revolut has confirmed the number of engineers, the model's identity or the exceptions list. No figures for cost savings are given.
It is also not stated which version of GLM is in use, how long the migration took, or whether the arrangement is permanent. The report links the approach to blockchain principles of individual control, but that is commentary rather than a stated company position.
