Mistral AI compute cluster at Eclairion (Bruyères-le-Châtel, Essonne)
DatacenterDynamics reported in March 2026 that Mistral AI raised USD 830 million of debt for a cluster of 13,800 NVIDIA GB300 GPUs at a data centre owned and run by Eclairion at Bruyères-le-Châtel south of Paris, with 44 MW of powered capacity and operations intended by the end of June 2026. An earlier plan named 18,000 GB200 GPUs and 40 MW. Sources differ on whether the cluster is already running, so the status is marked disputed.
