- Cooling
- Modular container design for 30 to 200 kW racks; cooling type is not specified in the sources we read.
Reported only. Trade press says operating since 2024 and hosting a Mistral AI cluster via Fluidstack. Sources disagree on capacity (up to 60 MW versus over 80 MW at full build), so no capacity entry is made. Operating status is as reported in early 2025, so no stage date is set.
What we checked
- A trade report of early 2025 says the site was operating since 2024 and hosts a Mistral AI training cluster under a multi-year deal with Fluidstack. (source)
